NAME

6       plmapfill  -  Plot all or a subset of Shapefile data, filling the poly‐
7       gons
8

SYNOPSIS

10       plmapfill(mapform, name, minx, maxx, miny, maxy, plotentries,  nploten‐
11       tries)
12

DESCRIPTION

14       As per plmapline(3plplot), however the items are filled in the same way
15       as plfill(3plplot).
16
17       Redacted form: plmapfill(mapform, name, minx, maxx, miny, maxy, ploten‐
18       tries)
19
20       This function is used in example 19.

ARGUMENTS

23       mapform (PLMAPFORM_callback(3plplot), input)
24              A  user  supplied function to transform the coordinates given in
25              the shapefile into a  plot  coordinate  system.  By  using  this
26              transform,  we  can change from a longitude, latitude coordinate
27              to a  polar  stereographic  project,  for  example.   Initially,
28              x[0]..[n-1]  are  the longitudes and y[0]..y[n-1] are the corre‐
29              sponding latitudes.  After the call to mapform(),  x[]  and  y[]
30              should  be replaced by the corresponding plot coordinates. If no
31              transform is desired, mapform can be replaced by NULL.
32
33       name (PLCHAR_VECTOR(3plplot), input)
34              An ascii character string specifying the file name of a  set  of
35              Shapefile files without the file extension.
36
37       minx (PLFLT(3plplot), input)
38              The  minimum  x  value  to  be plotted. This must be in the same
39              units as used by the Shapefile. You could use a very large nega‐
40              tive  number to plot everything, but you can improve performance
41              by limiting the area drawn. The units must match  those  of  the
42              Shapefile projection, which may be for example longitude or dis‐
43              tance. The value of minx must be less than the value of maxx.
44
45       maxx (PLFLT(3plplot), input)
46              The maximum x value to be plotted. You could use  a  very  large
47              number  to  plot  everything, but you can improve performance by
48              limiting the area drawn.
49
50       miny (PLFLT(3plplot), input)
51              The minimum y value to be plotted. This  must  be  in  the  same
52              units as used by the Shapefile. You could use a very large nega‐
53              tive number to plot everything, but you can improve  performance
54              by  limiting  the  area drawn. The units must match those of the
55              Shapefile projection, which may be for example latitude or  dis‐
56              tance. The value of miny must be less than the value of maxy.
57
58       maxy (PLFLT(3plplot), input)
59              The  maximum  y  value to be plotted. You could use a very large
60              number to plot everything, but you can  improve  performance  by
61              limiting the area drawn.
62
63       plotentries (PLINT_VECTOR(3plplot), input)
64              A vector containing the zero-based indices of the Shapefile ele‐
65              ments which will be drawn. Setting plotentries to NULL will plot
66              all elements of the Shapefile.
67
68       nplotentries (PLINT(3plplot), input)
69              The  number  of  items in plotentries. Ignored if plotentries is
70              NULL.
