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.
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.
Property expressions
PowerBuilder
You can modify properties using property expressions. For example,
to change the type of the graph gr_emp to Column, you could
code:
|
1 |
dw_empinfo.Object.gr_emp.GraphType = ColGraph! |
To change the title of the graph at execution time, you could
code:
|
1 |
dw_empinfo.Object.gr_emp.Title = "New title" |
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:
|
1 |
dw_empinfo.<span>Modify</span>("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:
|
1 |
dw_empinfo.<span>Modify</span>("gr_emp.Values.Label = 'New label'"); |
