Many Alpha Five users and developers have asked for graphing capabilities. It is possible to add pie, bar, and line graphs to Alpha Five applications using the ui_bitmap_create() and ui_bitmap_draw() functions built into A5v5. For example, here is a pie graph displayed from a form:
Figure 1. View of pie graph on form.
You can click on the different graph types to see how the graph changes. The graphing code is provided as an .aex file that is loaded into your "addins_installed" folder in your A5v5 installation folder. You can also navigate to the w_graph.adb database and run the "graph" form and experiment with how to use the graphing functions.
The graph functions are provided as shareware, not freeware. Illustrations are given in w_graph.adb for adding graphs to forms, reports, and Xdialogs. Feel free to download the function and database, but if you use them a nominal fee ($15 for personal use, $50 for commercial use) is requested.
