Chavier is a GUI application that let’s you explore PyCha. It can be launched from the command line with chavier.
The easiest way to get started is to generate some random data to play around with.
Tools -> Generate random points
The type of chart can be changed in the View menu. To change an option, just double click its entry or use the Edit menu.
Tools -> Dump chart state prints some chart information (size, ranges, etc.) to the console from which Chavier was launched.
