NAME

       bargraph - compile bar graphs into pic input

SYNOPSIS

       bargraph [ filename ...  ]

DESCRIPTION

       bargraph  is  a perl script which takes a set of Y data with labels and generates a (human
       readable) pic script that will produce the bar graph.  The output (pic input) is commented
       and  is  designed such that you should be able to go in and adjust it to fit your document
       should you need to do so.

       The input data format is:

           3 foo bar
           9 bigger foo
           "Silly example

       with output like

                             bigger
                              foo
                          +----------+
                          |          |
               foo        |          |
               bar        |          |
           +----------+   |          |
           |          |   |          |
           +----------+   +----------+
         -------------------------------
                3              9

OPTIONS

       The following command line options are available

       -big      Make the x/y defaults be 7.5 inches, crank up the title size, and  don't  put  a
                 spacer at the top.  Used for printing a graph on a full page.

       -nobox    Do not put an outline box around the bargraph.

CONTROL OPTIONS

       The  following may be included in the graph to control the format of the graph.  They must
       be at the beginning of a line and by themselves.

       %ps <ps>          point size.  Default is 10.

       %ft <ft>          font.  Default is CB.

       %labelgap <val>   the space in inches between fill labels.  The bars may  be  filled  with
                         different  fill  values  (no patterns yet, pic doesn't do that).  If you
                         want to label these, the labels are labelgap inches apart.   Default  is
                         1.5 inches.

       %xsize <val>      the width of the graph in inches.  Default is 7 inches.

       %ysize <val>      the height of the graph in inches.  Default is 6 inches.

       %Title n|s <title>
                         the  title of the bargraph.  The title option is followed by a a "n"orth
                         (top) or "s"outh (bottom) indicator  which  controls  placement  of  the
                         title.  No default.

       %titleplus <val>  increases the size of the title in pointsize.  Default is 0.

       %boxpercent <val> a value between 0 and 100 that controls how closely the bars are to each
                         other.  A value of 100 means the bars touch.  Default is 75.

       %worse <D> <W>    An idiot arrow is drawn to indicate which way  is  worse.   <D>  is  the
                         direction and must be "up" or "down".  <W> is the location specifier and
                         must be one of "n"orth, "w"est, "e"ast, "s"outh, "nw" northwest, ne, sw,
                         se, etc.

       %better <D> <W>   An  idiot  arrow  is  drawn to indicate which way is better.  <D> is the
                         direction and must be "up" or "down".  <W> is the location specifier and
                         must be one of "n"orth, "w"est, "e"ast, "s"outh, "nw" northwest, ne, sw,
                         se, etc.

       %fakemax          pretend that one data point was this big when autoscaling.  THis is used
                         to make a series of bargraphs be all drawn to the same scale.

FILL CONTROL

       Each datum may be follwed by a fill specifier as follows
            3 foo bar %fill.5
       Labels  may  be  specified  to group a set of data that all have the same data.  If a line
       appears like
            %label.5 The foo bar data
       then you get a label below the graph.

TODO

       Make a -horizontal option that prints the graphs the other way.

       Hack pick to get access to postscripts stipple patterns.

BUGS

       This isn't done.  It isn't integrated with the groff preprocessor yet.   It  doesn't  know
       about .GS/.GE thingys.  I use it to manually generate a pic file and then include that.  I
       have to talk to James to see if he wants it as part of the gpic stuff.
