DataWindow controls

An enumerated datatype specifying the To change the fill pattern, use a FillPattern value:
To change the symbol type, use a grSymbolType value:

Return Values
Integer. Returns 1 if it succeeds and
-1 if an error occurs. If any argument’s value is null, SetDataStyle returns null.
Usage
To change the appearance of a series, use SetSeriesStyle.
The settings you make for the series are the defaults for all data
points in the series.
For a graph in a DataWindow, you can specify the appearance
of a data point in the graph before PowerBuilder draws the graph.
To do so, define a user event for pbm_dwngraphcreate and
call SetDataStyle in the script for that event.
The event pbm_dwngraphcreate is triggered
just before a graph is created in a DataWindow object.
You cannot use a fill pattern or specify specific symbols
for the data point.
Examples
This example checks the fill pattern used for data
point 10 in the series named Costs in the graph gr_product_data.
If it is diamond, then SetDataStyle changes it
to solid:
1 |
integer SeriesNbr |
1 |
FillPattern data_pattern |
1 |
1 |
// Get the number of the series |
1 |
SeriesNbr = gr_product_data.FindSeries("Costs") |
1 |
1 |
// Get the current fill pattern |
1 |
gr_product_data.GetDataStyle(SeriesNbr, 10, & |
1 |
data_pattern) |
1 |
1 |
// If the pattern is diamond, change it to solid |
1 |
IF data_pattern = Diamond! THEN & |
1 |
gr_product_data.<span>SetDataStyle</span>(SeriesNbr, & |
1 |
10, Solid!) |
