When you define a graph in the DataWindow painter, you specify its behavior and appearance. For example, you might define a graph as a column graph with a certain title, divide its Value axis into four major divisions, and so on. Each of these entries corresponds to a property of a graph. For example, all graphs have a property GraphType, which specifies the type of graph.
When dynamically changing the graph type
If you change the graph type, be sure also to change the other
properties as needed to properly define the new graph.
You can change these graph properties at runtime by assigning values to the graph’s properties in code using the Modify or SetProperty methods.
For example, to change the title of graph gr_emp in DataWindowControl dwEmpInfo, you could write this code in Visual Basic:
dwEmpInfo.Modify("gr_emp.Title='New Title'")
