SYNOPSIS
plmap(mapform, type, minlong, maxlong, minlat, maxlat)DESCRIPTION
Plots continental outlines in world coordinates. examples/c/x19c demonstrates how to use this function to create different projections.
Redacted form: General: plmap(mapform, type, minlong, maxlong, minlat, maxlat) F95, Java, Perl/PDL, Python: Not implemented?
This function is used in example 19.
ARGUMENTS
- mapform (void (*) (PLINT, PLFLT *, PLFLT *), input)
- A user supplied function to transform the coordinate longitudes and latitudes to 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.
- type (const char *, input)
-
type is a character string. The value of this parameter determines the type of background. The possible values are: "globe" -- continental outlines
"usa" -- USA and state boundaries
"cglobe" -- continental outlines and countries
"usaglobe" -- USA, state boundaries and continental outlines
- minlong (PLFLT, input)
- The value of the longitude on the left side of the plot. The value of minlong must be less than the value of maxlong, and the quantity maxlong-minlong must be less than or equal to 360.
- maxlong (PLFLT, input)
- The value of the longitude on the right side of the plot.
- minlat (PLFLT, input)
- The minimum latitude to be plotted on the background. One can always use -90.0 as the boundary outside the plot window will be automatically eliminated. However, the program will be faster if one can reduce the size of the background plotted.
- maxlat (PLFLT, input)
-
The maximum latitudes to be plotted on the background. One can always use 90.0 as the boundary outside the plot window will be automatically eliminated.
