RainPro is a collection of functions which take data and make high-quality charts. These can be shown on-screen with the supplied viewer, saved to the clipboard, printed or exported as VML, SVG, PDF, metafile or PNG/DCX image formats. You can (of course) include the charts in your own GUI application either using the built-in DRAW method or the supplied OCX chart viewer.

It really is as easy as calling any other APL function, and once you have made your charts you can publish them on the internet in any of the 3 popular vector formats (VML, SVG, PDF) or save them as PNG or GIF images direct from your APL application.
