plmeridians: Plot latitude and longitude lines

public void meridians(MapFunc mapform, Double dlong, Double dlat, Double minlong, Double maxlong, Double minlat, Double maxlat)

Type	Name	Description
MapFunc	mapform	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.
Double	dlong	The interval in degrees at which the longitude lines are to be plotted.
Double	dlat	The interval in degrees at which the latitude lines are to be plotted.
Double	minlong	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.
Double	maxlong	The value of the longitude on the right side of the plot.
Double	minlat	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.
Double	maxlat	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.

Displays latitude and longitude on the current plot. The lines are plotted in the current color and line style.
