. This demo produces 3 different plots, retrieves a bitmap of same plot, and displays the bitmap in its own window, all while DPlot or DPlot Jr are hidden in the background.As I don't yet have my copy of PowerBasic I won't be able to answer many questions about it, but that will change soon. And in any case I'm sure Andrew or others can answer questions you might have, so feel free to chime in.
You can get the zipped source files here: [Edit: link removed. PowerBasic demos are now included with the DPLOTLIB and DPlot Jr distributions]
