mgdgvars__define.pro

includes main-level program

Object to save/restore direct graphics system variables. This is needed when using multiple graphics windows and it is necessary to use the coordinate system of a window which does not contain the last item plotted. For example, this happens when using WSET to change to a graphics window containing a plot (but not the most recently plotted) and overplotting or using CONVERT_COORD with the coordinate system of that window.

Examples

See the main-level example program at the end of the file:
