NAME

       plmapstring  -  Plot  all  or  a subset of Shapefile data using strings or points in world
       coordinates

SYNOPSIS

       plmapstring(mapform, name, string, minx, maxx, miny, maxy, plotentries, nplotentries)

DESCRIPTION

       As per plmapline(3plplot), however the items are plotted as strings or points in the  same
       way as plstring(3plplot).

       Redacted form: plmapstring(mapform, name, string, minx, maxx, miny, maxy, plotentries)

       This function is not used in any examples.

ARGUMENTS

       mapform (PLMAPFORM_callback(3plplot), input)
              A user supplied function to transform the coordinates given in the shapefile into a
              plot coordinate system. By using this transform, we can change  from  a  longitude,
              latitude  coordinate  to  a  polar  stereographic project, for example.  Initially,
              x[0]..[n-1] are the longitudes and y[0]..y[n-1] are  the  corresponding  latitudes.
              After  the  call  to mapform(), x[] and y[] should be replaced by the corresponding
              plot coordinates. If no transform is desired, mapform can be replaced by NULL.

       name (PLCHAR_VECTOR(3plplot), input)
              An ascii character string specifying the file name of  a  set  of  Shapefile  files
              without the file extension.

       string (PLCHAR_VECTOR(3plplot), input)
              A UTF-8 character string to be drawn.

       minx (PLFLT(3plplot), input)
              The  minimum  x  value to be plotted. This must be in the same units as used by the
              Shapefile. You could use a very large negative number to plot everything,  but  you
              can  improve  performance by limiting the area drawn. The units must match those of
              the Shapefile projection, which may be for example longitude or distance. The value
              of minx must be less than the value of maxx.

       maxx (PLFLT(3plplot), input)
              The  maximum  x  value  to  be  plotted.  You could use a very large number to plot
              everything, but you can improve performance by limiting the area drawn.

       miny (PLFLT(3plplot), input)
              The minimum y value to be plotted. This must be in the same units as  used  by  the
              Shapefile.  You  could use a very large negative number to plot everything, but you
              can improve performance by limiting the area drawn. The units must match  those  of
              the  Shapefile projection, which may be for example latitude or distance. The value
              of miny must be less than the value of maxy.

       maxy (PLFLT(3plplot), input)
              The maximum y value to be plotted. You could  use  a  very  large  number  to  plot
              everything, but you can improve performance by limiting the area drawn.

       plotentries (PLINT_VECTOR(3plplot), input)
              A  vector containing the zero-based indices of the Shapefile elements which will be
              drawn. Setting plotentries to NULL will plot all elements of the Shapefile.

       nplotentries (PLINT(3plplot), input)
              The number of items in plotentries.  Ignored if plotentries is NULL.
