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 execution time by assigning values to the graph’s properties in code.
PowerBuilder You can modify properties using property expressions. For example, to change the type of the graph gr_emp to Column, you could code:
dw_empinfo.Object.gr_emp.GraphType = ColGraph!
To change the title of the graph at execution time, you could code:
dw_empinfo.Object.gr_emp.Title = "New title"
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:
dw_empinfo.Modify("gr_emp.Title = 'New title'")
Example for Web ActiveX This example changes the label text for the Value axis of graph gr_emp in the DataWindow control dw_empinfo:
dw_empinfo.Modify("gr_emp.Values.Label = 'New label'");
For a complete list of graph properties, see the DataWindow Reference.
