Getting information about the data

There are quite a few methods for getting information about data
in a graph in a DataWindow control at execution time. For all methods,
you provide the name of the graph within the DataWindow as the first
argument. You can provide your own name for graph controls when you
insert them in the DataWindow painter. If the presentation style is
Graph, you do not need to name the graph.

PowerBuilder

These methods get information about the data and its display. For
several of them, an argument is passed by reference to hold the
requested information:

CategoryCount	The number of categories in a graph

DataCount	The number of data points in a series
