Specifies the appearance of a data point in a graph. The data point's series has appearance settings that you can override with SetDataStyle.
Description
Specifies the colors of a data point in a graph.
Applies to
PowerBuilder DataWindow
DataWindow control
Syntax
PowerBuilder
integer dwcontrol.SetDataStyle ( string graphcontrol, integer seriesnumber, integer datapointnumber, grColorType colortype, long color )
|
Argument |
Description |
|---|---|
|
dwcontrol |
A reference to the DataWindow control containing the graph. |
|
graphcontrol |
A string whose value is the name of the graph in the DataWindow control. |
|
seriesnumber |
The number of the series in which you want to set the color of a data point. |
|
datapointnumber |
The number of the data point for which you want to set the color. |
|
colortype |
A value of the grColorType enumerated datatype (in PowerBuilder) specifying the aspect of the data point for which you want to set the color. For a list of values, see grColorType. |
|
color |
A long whose value is the new color for colortype. |
Return value
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.
To reset the color of individual points back to the series color, call ResetDataColors.
You can specify the appearance of a data point in the graph before the application 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.
Using SetDataStyle with DirectX 3D Graphs
You can only set the color for the foreground. Background, line color, and shade are not supported.
Examples
PowerBuilder
These statements set the text (foreground) color to black for data point 6 in the series named Salary in the graph gr_depts in the DataWindow control dw_employees:
integer SeriesNbr
// Get the number of the series
SeriesNbr = &
dw_employees.FindSeries("gr_depts" , "Salary")
// Set the background color
dw_employees.SetDataStyle("gr_depts" , SeriesNbr, &
6, Background!, 0)See also
Description
Specifies the style and width of a data point's line in a graph.
Applies to
PowerBuilder DataWindow
DataWindow control
Syntax
PowerBuilder
integer dwcontrol.SetDataStyle ( string graphcontrol, integer seriesnumber, integer datapointnumber, LineStyle linestyle, { integer linewidth } )
|
Argument |
Description |
|---|---|
|
dwcontrol |
A reference to the DataWindow control containing the graph. |
|
graphcontrol |
A string whose value is the name of the graph in the DataWindow control. |
|
seriesnumber |
The number of the series in which you want to set the line style and width of a data point. |
|
datapointnumber |
The number of the data point for which you want to set the line style and width. |
|
linestyle |
A value of the LineStyle enumerated datatype (in PowerBuilder) specifying a line style pattern of dots, dashes, and solid lines. For a list of line style values, see LineStyle. |
|
linewidth (optional for PowerBuilder) |
An integer whose value is the width of the line in pixels. |
Return value
Returns 1 if it succeeds and -1 if an error occurs. If any argument's value is null, SetDataStyle returns null.
Usage

Examples
PowerBuilder
This example checks the line style used for data point 10 in the series named Costs in the graph gr_computers in the DataWindow control dw_equipment. If it is dash-dot, the SetDataStyle sets it to continuous. The line width stays the same:
integer SeriesNbr, line_width
LineStyle line_style
// Get the number of the series
SeriesNbr = dw_equipment.FindSeries( &
"gr_computers", "Costs")
// Get the current line style
dw_equipment.GetDataStyle("gr_computers", &
SeriesNbr, 10, line_style, line_width)
// If the pattern is dash-dot, change to continuous
IF line_style = DashDot! THEN &
dw_equipment.SetDataStyle("gr_computers", &
SeriesNbr, 10, Continuous!, line_width)See also
Description
Specifies the fill pattern for a data point in a graph.

|
datapointnumber |
