There are quite a few methods for getting information about data in a graph in a DataWindow control at runtime. 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.
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:
