Extend the S_TOOLS-STx graphics library to enable graphs to be rotated and flipped horizontally or vertically without having to recalculate the data.
The base graphics object class was modified, adding rotation and flip settings. A new macro command was implemented to set a graph's rotation-and-flip values. Each graphic object was then modified to display itself correctly according to these settings.
Rotating and flipping graphical representations of data can now be achieved with on-macro command, rather than having to modify the data itself.
