DESCRIPTION

       plot2time draws plots where the horizontal axis represents time. The time axis can be labelled in various
       different ways including MJD, decimal year and ISO-8601 form.

       Positional  coordinates  are specified as t, y pairs, e.g.: plot2time in1=series.cdf layer1=line t1=EPOCH
       y1=ENERGY

       This command, unlike the other plot2* commands at time of writing, can be used to draw multi-zone  plots.
       These  are  plots  with different panels stacked vertically so that different datasets can share the same
       horizontal (time) axis, but have separate vertical axes, colour maps, legends etc.  The  horizontal  axes
       are  always  synchronized  between  zones. This is currently controlled with the zoneN parameter. For any
       layer with a layer suffix N, you can specify a zone identifier as an arbitrary string,  Z,  by  supplying
       the  parameter zoneN=Z. Layers with the same value of zoneN are plotted in the same zone, and layers with
       different values are plotted in different zones. If no zoneN is given, the layer is assigned to a  single
       (unnamed)  zone,  so with no zone parameters specified all plots appear in a single zone. Parameters spe‐
       cific to a given zone can then be suffixed with the same Z zone identifier. The examples  section  illus‐
       trates what this looks like in practice.

       Note: this plot type, and the multi-zone feature, is experimental. As currently implemented it lacks some
       important features. The interface may be changed in a future version.

       Content is added to the plot by specifying one or more plot layers using the layerN parameter. The N part
       is  a  suffix  applied  to  all  the  parameters affecting a given layer; any suffix (including the empty
       string) may be used. Available layers for this plot type are: mark,  line,  fill,  quantile,  grid,  his‐
       togram, kde, knn, densogram, gaussian, yerror, spectrogram, label, function.

OPTIONS

       xpix=<int-value>
              Size  of  the  output image in the X direction in pixels. This includes space for any axis labels,
              padding and other decoration outside the plot area itself. See also insets.

       ypix=<int-value>
              Size of the output image in the Y direction in pixels. This includes space for  any  axis  labels,
              padding and other decoration outside the plot area itself. See also insets.

       insets=<top>,<left>,<bottom>,<right>
              Defines the amount of space in pixels around the actual plotting area. This space is used for axis
              labels, and other decorations and any left over forms an empty border.

              The  size and position of the actual plotting area is determined by this parameter along with xpix
              and ypix.

              The value of this parameter is 4 comma separated integers: <top>,<left>,<bottom>,<right>.  Any  or
              all  of  these values may be left blank, in which case the corresponding margin will be calculated
              automatically according to how much space is required.

       omode=swing|out|cgi|discard|auto
              Determines how the drawn plot will be output, see SUN/256.

                * swing: Plot will be displayed in a window on the screen. This plot is "live"; it  can  be  re‐
                  sized  and (except for old-style plots) navigated around with mouse actions in the same way as
                  plots in TOPCAT.

                * out: Plot will be written to a file given by out using the graphics format given by ofmt.

                * cgi: Plot will be written in a way suitable for CGI use direct from a web server.  The  output
                  is in the graphics format given by ofmt, preceded by a suitable "Content-type" declaration.

                * discard: Plot is drawn, but discarded. There is no output.

                * auto: Behaves as swing or out mode depending on presence of out parameter

       storage=simple|cache|basic-cache
              Determines  the way that data is accessed when constructing the plot. There are two basic options,
              cached or not.

              If no caching is used (simple) then rows are read sequentially from the specified  input  table(s)
              every  time  they  are required. This generally requires a small memory footprint (though that can
              depend on how the table is specified) and makes sense if the data only needs to be scanned once or
              perhaps if the table is very large.

              If caching is used (cache) then the required data is read once from the specified  input  table(s)
              and  cached  before any plotting is performed, and plots are done using this cached data. This may
              use a significant amount of memory for large tables but it's usually more sensible (faster) if the
              data will need to be scanned multiple times.

              The default value is cache if a live plot is being generated (omode=swing), since in that case the
              plot needs to be redrawn every time the user performs plot navigation actions or resizes the  win‐
              dow,  or  if animations are being produced. Otherwise (e.g. output to a graphics file) the default
              is simple.

       seq=<suffix>[,...]
              Contains a comma-separated list of layer suffixes to determine the order in which layers are drawn
              on the plot. This can affect which symbol are plotted on top of, and so potentially obscure, which
              other ones.

              When specifying a plot, multiple layers may be specified, each introduced by a parameter layer<N>,
              where <N> is a different (arbitrary) suffix labelling the layer, and is appended to all the  para‐
              meters specific to defining that layer.

              By  default the layers are drawn on the plot in the order in which the layer* parameters appear on
              the command line. However if this parameter is specified, each comma-separated element  is  inter‐
              preted  as  a  layer  suffix, giving the ordered list of layers to plot. Every element of the list
              must be a suffix with a corresponding layer parameter, but missing or repeated  elements  are  al‐
              lowed.

       legend=true|false
              Whether  to  draw  a legend or not. If no value is supplied, the decision is made automatically: a
              legend is drawn only if it would have more than one entry.

       legborder=true|false
              If true, a line border is drawn around the legend.

       legopaque=true|false
              If true, the background of the legend is opaque, and the legend obscures any plot  components  be‐
              hind it. Otherwise, it's transparent.

       legseq=<suffix>[,...]
              Determines which layers are represented in the legend (if present) and in which order they appear.
              The legend has a line for each layer label (as determined by the leglabelN parameter). If multiple
              layers have the same label, they will contribute to the same entry in the legend, with style icons
              plotted  over  each other. The value of this parameter is a comma-separated sequence of layer suf‐
              fixes, which determines the order in which the legend entries appear. Layers with suffixes missing
              from this list do not show up in the legend at all.

              If no value is supplied (the default), the sequence is the same as  the  layer  plotting  sequence
              (see seq).

       legpos=<xfrac,yfrac>
              Determines the internal position of the legend on the plot. The value is a comma-separated pair of
              values  giving  the  X  and  Y positions of the legend within the plotting bounds, so for instance
              "0.5,0.5" will put the legend right in the middle of the plot. If no value is supplied, the legend
              will appear outside the plot boundary.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g.  legposZ  af‐
              fects only zone Z.

       title=<value>
              Text  of  a  title to be displayed at the top of the plot. If null, the default, no title is shown
              and there's more space for the graphics.

              If a zone suffix is appended to the parameter name, only that zone is affected,  e.g.  titleZ  af‐
              fects only zone Z.

       auxmap=<map-name>|<color>-<color>[-<color>...]
              Color map used for Aux axis shading.

              A mixed bag of colour ramps are available: inferno, magma, plasma, viridis, cubehelix, sron, rain‐
              bow,  rainbow2, rainbow3, pastel, accent, gnuplot, gnuplot2, specxby, set1, paired, hotcold, rdbu,
              piyg, brbg, cyan-magenta, red-blue, brg, heat, cold, light,  greyscale,  colour,  standard,  bugn,
              bupu,  orrd, pubu, purd, huecl, hue, intensity, rgb_red, rgb_green, rgb_blue, hsv_h, hsv_s, hsv_v,
              yuv_y, yuv_u, yuv_v, scale_hsv_s, scale_hsv_v, scale_yuv_y, mask, blacker,  whiter,  transparency.
              Note: many of these, including rainbow-like ones, are frowned upon by the visualisation community.

              You  can  also construct your own custom colour map by giving a sequence of colour names separated
              by minus sign ("-") characters. In this case the ramp is a linear interpolation between each  pair
              of  colours  named, using the same syntax as when specifying a colour value. So for instance "yel‐
              low-hotpink-#0000ff" would shade from yellow via hot pink to blue.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g.  auxmapZ  af‐
              fects only zone Z.

       auxclip=<lo>,<hi>
              Defines  a  subrange  of  the  colour ramp to be used for Aux shading. The value is specified as a
              (low,high) comma-separated pair of two numbers between 0 and 1.

              If the full range 0,1 is used, the whole range of colours specified by the selected shader will be
              used. But if for instance a value of 0,0.5 is given, only those colours at the left  hand  end  of
              the ramp will be seen.

              If  the null (default) value is chosen, a default clip will be used. This generally covers most or
              all of the range 0-1 but for colour maps which fade to white, a small proportion of the lower  end
              may  be  excluded,  to ensure that all the colours are visually distinguishable from a white back‐
              ground. This default is usually a good idea if the colour map is being used with something like  a
              scatter  plot, where markers are plotted against a white background. However, for something like a
              density map when the whole plotting area is tiled with colours from the map, it may be  better  to
              supply the whole range 0,1 explicitly.

              If  a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxclipZ af‐
              fects only zone Z.

       auxflip=true|false
              If true, the colour map on the Aux axis will be reversed.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxflipZ  af‐
              fects only zone Z.

       auxquant=<number>
              Allows  the colour map used for the Aux axis to be quantised. If an integer value N is chosen then
              the colour map will be viewed as N discrete evenly-spaced levels, so that only N different colours
              will appear in the plot. This can be used to generate a contour-like effect, and may make it easi‐
              er to trace the boundaries of regions of interest by eye.

              If left blank, the colour map is nominally continuous (though in practice it may be quantised to a
              medium-sized number like 256).

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxquantZ af‐
              fects only zone Z.

       auxfunc=log|linear|sqrt|square
              Defines the way that values in the Aux range are mapped to the selected colour ramp.

              The available options are:

                * log: Logarithmic scaling

                * linear: Linear scaling

                * sqrt: Square root scaling

                * square: Square scaling

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxfuncZ  af‐
              fects only zone Z.

       auxmin=<number>
              Minimum value of the data coordinate on the Aux axis. This sets the value before any subranging is
              applied. If not supplied, the value is determined from the plotted data.

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. auxminZ af‐
              fects only zone Z.

       auxmax=<number>
              Maximum value of the data coordinate on the Aux axis. This sets the value before any subranging is
              applied. If not supplied, the value is determined from the plotted data.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g.  auxmaxZ  af‐
              fects only zone Z.

       auxlabel=<text>
              Sets the label used to annotate the aux axis, if it is visible.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxlabelZ af‐
              fects only zone Z.

       auxcrowd=<factor>
              Determines how closely the tick marks are spaced on the Aux axis, if visible. The default value is
              1,  meaning  normal  crowding. Larger values result in more ticks, and smaller values fewer ticks.
              Tick marks will not however be spaced so closely that the labels overlap each  other,  so  to  get
              very closely spaced marks you may need to reduce the font size as well.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxcrowdZ af‐
              fects only zone Z.

       auxwidth=<pixels>
              Determines the lateral size of the aux colour ramp, if visible, in pixels.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. auxwidthZ af‐
              fects only zone Z.

       auxvisible=true|false
              Determines whether the aux axis colour ramp is displayed alongside the plot.

              If not supplied (the default), the aux axis will be visible when aux shading is used in any of the
              plotted layers.

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. auxvisibleZ
              affects only zone Z.

       forcebitmap=true|false
              Affects whether rendering of the data contents of a plot (though not axis labels  etc)  is  always
              done  to  an  intermediate bitmap rather than, where possible, being painted using graphics primi‐
              tives. This is a rather arcane setting that may nevertheless have noticeable effects  on  the  ap‐
              pearance  and  size  of  an output graphics file, as well as plotting time. For some types of plot
              (e.g. shadingN=auto or shadingN=density) it will have no effect, since this kind of rendering hap‐
              pens in any case.

              When writing to vector graphics formats (PDF and PostScript), setting it true will force the  data
              contents to be bitmapped. This may make the output less beautiful (round markers will no longer be
              perfectly round), but it may result in a much smaller file if there are very many data points.

              When  writing to bitmapped output formats (PNG, GIF, JPEG, ...), it fixes shapes to be the same as
              seen on the screen rather than be rendered at the mercy of the graphics  system,  which  sometimes
              introduces small distortions.

       compositor=0..1
              Defines  how  multiple  overplotted  partially transparent pixels are combined to form a resulting
              colour. The way this is used depends on the details of the specified plot.

              Currently, this parameter takes a "boost" value in the range 0..1. If the value is  zero,  satura‐
              tion  semantics are used: RGB colours are added in proporition to their associated alpha value un‐
              til the total alpha is saturated (reaches 1), after which additional pixels have  no  further  ef‐
              fect.  For  larger  boost  values,  the effect is similar, but any non-zero alpha in the output is
              boosted to the given minimum value. The effect of this is that even very slightly populated pixels
              can be visually distinguished from unpopulated ones which may not be the case for saturation  com‐
              position.

       animate=<table>
              If  not null, this parameter causes the command to create a sequence of plots instead of just one.
              The parameter value is a table with one row for each frame to be produced. Columns  in  the  table
              are  interpreted  as parameters which may take different values for each frame; the column name is
              the parameter name, and the value for a given frame is its value from  that  row.  Animating  like
              this is considerably more efficient than invoking the STILTS command in a loop.

              The location of the animation control table. This may take one of the following forms:

                * A filename.

                * A URL.

                * The special value "-", meaning standard input. In this case the input format must be given ex‐
                  plicitly using the afmt parameter. Note that not all formats can be streamed in this way.

                * A  system command line with either a "<" character at the start, or a "|" character at the end
                  ("<syscmd" or "syscmd|"). This executes the given pipeline and reads from its standard output.
                  This will probably only work on unix-like systems.
               In any case, compressed data in one of the supported compression formats (gzip, Unix compress  or
              bzip2) will be decompressed transparently.

       afmt=<in-format>
              Specifies  the  format of the animation control table as specified by parameter animate. The known
              formats are listed in SUN/256. This flag can be used if you know what format your table is in.  If
              it  has  the special value (auto) (the default), then an attempt will be made to detect the format
              of the table automatically. This cannot always be done correctly however, in which case  the  pro‐
              gram will exit with an error explaining which formats were attempted.

       astream=true|false
              If  set  true,  the  animation  control table specified by the animate parameter will be read as a
              stream. It is necessary to give the afmt parameter in this case. Depending on the required  opera‐
              tions  and processing mode, this may cause the read to fail (sometimes it is necessary to read the
              table more than once). It is not normally necessary to set this flag; in most cases the data  will
              be streamed automatically if that is the best thing to do. However it can sometimes result in less
              resource usage when processing large files in certain formats (such as VOTable).

       acmd=<cmds>
              Specifies processing to be performed on the animation control table as specified by parameter ani‐
              mate,  before  any other processing has taken place. The value of this parameter is one or more of
              the filter commands described in SUN/256. If more than one is given, they  must  be  separated  by
              semicolon characters (";"). This parameter can be repeated multiple times on the same command line
              to  build  up  a  list of processing steps. The sequence of commands given in this way defines the
              processing pipeline which is performed on the table.

              Commands may alteratively be supplied in an external file, by using the indirection character '@'.
              Thus a value of "@filename" causes the file filename to be read for a list of filter  commands  to
              execute. The commands in the file may be separated by newline characters and/or semicolons.

       parallel=<int-value>
              Determines  how many threads will run in parallel if animation output is being produced. Only used
              if the animate parameter is supplied. The default value is the  number  of  processors  apparently
              available to the JVM.

       ylog=true|false
              If false (the default), the scale on the Y axis is linear, if true it is logarithmic.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. ylogZ affects
              only zone Z.

       yflip=true|false
              If  true,  the  scale  on the Y axis will increase in the opposite sense from usual (e.g. right to
              left rather than left to right).

              If a zone suffix is appended to the parameter name, only that zone is affected,  e.g.  yflipZ  af‐
              fects only zone Z.

       tlabel=<text>
              Gives a label to be used for annotating the Time axis. If not supplied no label will be drawn.

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. tlabelZ af‐
              fects only zone Z.

       ylabel=<text>
              Gives a label to be used for annotating axis Y A default value based on the plotted data  will  be
              used if no value is supplied.

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. ylabelZ af‐
              fects only zone Z.

       grid=true|false
              If true, grid lines are drawn on the plot at positions determined by  the  major  tick  marks.  If
              false, they are absent.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. gridZ affects
              only zone Z.

       tcrowd=<number>
              Determines how closely the tick marks are spaced on the Time axis. The default value is 1, meaning
              normal  crowding.  Larger  values result in more ticks, and smaller values fewer ticks. Tick marks
              will not however be spaced so closely that the labels overlap each other, so to get  very  closely
              spaced marks you may need to reduce the font size as well.

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. tcrowdZ af‐
              fects only zone Z.

       ycrowd=<number>
              Determines how closely the tick marks are spaced on the Y axis. The default value  is  1,  meaning
              normal  crowding.  Larger  values result in more ticks, and smaller values fewer ticks. Tick marks
              will not however be spaced so closely that the labels overlap each other, so to get  very  closely
              spaced marks you may need to reduce the font size as well.

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. ycrowdZ af‐
              fects only zone Z.

       tformat=iso-8601|year|mjd|unix
              Selects the way in which time values are represented when using them to label the time axis.

              The available options are:

                * iso-8601: ISO 8601 date, of the form yyyy-mm-ddThh:mm:ss.s (e.g. "2012-03-13T04")

                * year: Decimal year (e.g. "2012.197")

                * mjd: Modified Julian Date (e.g. "55999.2")

                * unix: Seconds since midnight of 1 Jan 1970 (e.g. "1331613420")

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. tformatZ  af‐
              fects only zone Z.

       minor=true|false
              If  true,  minor tick marks are painted along the axes as well as the major tick marks. Minor tick
              marks do not have associated grid lines.

              If a zone suffix is appended to the parameter name, only that zone is affected,  e.g.  minorZ  af‐
              fects only zone Z.

       texttype=plain|antialias|latex
              Determines  how  to turn label text into characters on the plot. Plain and Antialias both take the
              text at face value, but Antialias smooths the characters.  LaTeX  interprets  the  text  as  LaTeX
              source code and typesets it accordingly.

              When not using LaTeX, antialiased text usually looks nicer, but can be perceptibly slower to plot.
              At  time of writing, on MacOS antialiased text seems to be required to stop the writing coming out
              upside-down for non-horizontal text (MacOS java bug).

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. texttypeZ af‐
              fects only zone Z.

       fontsize=<int-value>
              Size of the text font in points.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. fontsizeZ af‐
              fects only zone Z.

       fontstyle=standard|serif|mono
              Font style for text.

              The available options are:

                * standard

                * serif

                * mono

              If a zone suffix is appended to the parameter name, only that zone is  affected,  e.g.  fontstyleZ
              affects only zone Z.

       fontweight=plain|bold|italic|bold_italic
              Font weight for text.

              The available options are:

                * plain

                * bold

                * italic

                * bold_italic

              If  a  zone suffix is appended to the parameter name, only that zone is affected, e.g. fontweightZ
              affects only zone Z.

       tmin=<year-or-iso8601>
              Minimum value of the time coordinate plotted. This sets the value before  any  subranging  is  ap‐
              plied. If not supplied, the value is determined from the plotted data.

              The  value may be set with a string that can be interpreted as a decimal year (e.g. "2007.521") or
              an ISO-8601 string (e.g. "2007-07-10T03:57:36", "2007-07-10T03"  or  "2007-07-10").  Note  however
              that  the numeric value of this configuration item if accessed programmatically is seconds since 1
              Jan 1970.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. tminZ affects
              only zone Z.

       tmax=<year-or-iso8601>
              Maximum value of the time coordinate plotted. This sets the value before  any  subranging  is  ap‐
              plied. If not supplied, the value is determined from the plotted data.

              The  value may be set with a string that can be interpreted as a decimal year (e.g. "2007.521") or
              an ISO-8601 string (e.g. "2007-07-10T03:57:36", "2007-07-10T03"  or  "2007-07-10").  Note  however
              that  the numeric value of this configuration item if accessed programmatically is seconds since 1
              Jan 1970.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. tmaxZ affects
              only zone Z.

       tsub=<lo>,<hi>
              Defines a normalised adjustment to the data range of the Time axis. The value may be specified  as
              a comma-separated pair of two numbers, giving the lower and upper bounds of the range of of inter‐
              est respectively. This sub-range is applied to the data range that would otherwise be used, either
              automatically  calculated  or  explicitly supplied; zero corresponds to the lower bound and one to
              the upper.

              The default value "0,1" therefore has no effect. The range could be restricted to its  lower  half
              with the value 0,0.5.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. tsubZ affects
              only zone Z.

       ymin=<number>
              Minimum  value  of the data coordinate on the Y axis. This sets the value before any subranging is
              applied. If not supplied, the value is determined from the plotted data.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. yminZ affects
              only zone Z.

       ymax=<number>
              Maximum value of the data coordinate on the Y axis. This sets the value before any  subranging  is
              applied. If not supplied, the value is determined from the plotted data.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. ymaxZ affects
              only zone Z.

       ysub=<lo>,<hi>
              Defines  a  normalised adjustment to the data range of the Y axis. The value may be specified as a
              comma-separated pair of two numbers, giving the lower and upper bounds of the range of of interest
              respectively. This sub-range is applied to the data range that would otherwise be used, either au‐
              tomatically calculated or explicitly supplied; zero corresponds to the lower bound and one to  the
              upper.

              The  default  value "0,1" therefore has no effect. The range could be restricted to its lower half
              with the value 0,0.5.

              If a zone suffix is appended to the parameter name, only that zone is affected, e.g. ysubZ affects
              only zone Z.

       navaxes=t|y|ty
              Determines the axes which are affected by the interactive navigation actions (pan and  zoom).  The
              default  is  t which means that the various mouse gestures will provide panning and zooming in the
              Time direction only. However, if it is set to ty mouse actions will affect both the horizontal and
              vertical axes.

       zoomfactor=<number>
              Sets the amount by which the plot view zooms in or out for each unit of mouse  wheel  movement.  A
              value of 1 means that mouse wheel zooming has no effect. A higher value means that the mouse wheel
              zooms faster and a value nearer 1 means it zooms slower. Values below 1 are not permitted.

       leglabelN=<text>
              Sets the presentation label for the layer with a given suffix. This is the text which is displayed
              in the legend, if present. Multiple layers may use the same label, in which case they will be com‐
              bined to form a single legend entry.

              If no value is supplied (the default), the suffix itself is used as the label.

       layerN=<layer-type> <layerN-specific-params>
              Selects  one of the available plot types for layerN. A plot consists of a plotting surface, set up
              using the various unsuffixed parameters of the plotting command, and zero  or  more  plot  layers.
              Each  layer  is introduced by a parameter with the name layer<N> where the suffix "<N>" is a label
              identifying the layer and is appended to all the parameter names which configure that layer.  Suf‐
              fixes may be any string, including the empty string.

              This parameter may take one of the following values, described in more detail in SUN/256:

                * mark

                * line

                * fill

                * quantile

                * grid

                * histogram

                * kde

                * knn

                * densogram

                * gaussian

                * yerror

                * spectrogram

                * label

                * function

              Each  of  these layer types comes with a list of type-specific parameters to define the details of
              that layer, including some or all of the following groups:

                * input table parameters (e.g. inN, icmdN)

                * coordinate params referring to input table columns (e.g. xN, yN)

                * layer style parameters (e.g. shadingN, colorN)

              Every parameter notionally carries the same suffix N. However, if the suffix is not  present,  the
              application  will  try  looking for a parameter with the same name with no suffix instead. In this
              way, if several layers have the same value for a given parameter (for instance input  table),  you
              can  supply it using one unsuffixed parameter to save having to supply several parameters with the
              same value but different suffixes.

       zoneN=<text>
              Defines which plot zone the layer with suffix N will appear in. This only makes sense  for  multi-
              zone  plots.  The actual value of the parameter is not significant, it just serves as a label, but
              different layers will end up in the same plot zone if they give the same values for  this  parame‐
              ter.
