After you have modified various chart objects (headings etc.), you may want to recover the modified PostScript code to save on file, view in the standard RainPro viewer, export to the Acrobat Distiller, and so on. To access the updated page (assuming you drew the chart on gui object ‘pgi’):

PG„#.PostScrp.GetPage '#.pgi'

You might like to check this in the normal viewer during development to check that the modifications have been applied correctly.
