Modifying graph properties

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.

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 execution time by
assigning values to the graph’s properties in code.

Property expressions


You can modify properties using property expressions. For example,
to change the type of the graph gr_emp to Column, you could

To change the title of the graph at execution time, you could

Modify method

In any environment , you can use the Modify method to reference
parts of a graph.

Example for PowerBuilder

For example, to change the title of graph gr_emp in
DataWindow control dw_empinfo, you could code:

Example for Web ActiveX

This example changes the label text for the Value axis of
graph gr_emp in the DataWindow control dw_empinfo:
