Specifies the appearance of a series in a graph. There are several syntaxes, depending on what settings you want to change.
To |
Use |
|---|---|
Set the series’ colors |
|
Set the line style and width |
|
Set the fill pattern or symbol for the series |
|
Specify that the series is an overlay |
Specifies the colors of a series in a graph.
Graph controls in windows and user objects, and graphs in DataWindow controls
controlname.SetSeriesStyle ( { graphcontrol, } seriesname, colortype, color )
Argument |
Description |
|---|---|
controlname |
The name of the graph in which you want to set the color of a series, or the name of the DataWindow control containing the graph. |
graphcontrol (DataWindow control only) (optional) |
A string whose value is the name of the graph in the DataWindow control for which you want to set the color of a series. |
seriesname |
A string whose value is the name of the series for which you want to set the color. |
colortype |
A value of the grColorType enumerated datatype specifying the item for which you want to set the color. Values are:
|
color |
A long specifying the new color for colortype. |
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value is null, SetSeriesStyle returns null.
Data points in a series can have their own style settings. Settings made with SetDataStyle set the style of individual data points and override series settings.
The graph stores style information for properties that do not apply to the current graph type. For example, you can set the fill pattern in a two-dimensional line graph or the line style in a bar graph, but that fill pattern or line style will not be visible.
For a graph in a DataWindow, you can specify the appearance of a series in the graph before PowerBuilder draws the graph. To do so, define a user event for pbm_dwngraphcreate and call SetSeriesStyle in the script for that event. The event pbm_dwngraphcreate is triggered just before a graph is created in a DataWindow object.
Using SetSeriesStyle with DirectX 3D Graphs
You can only set the color for the foreground. Background,
line color, and shade are not supported.
This statement sets the text (foreground) color of the series named Salary in the graph gr_emp_data to black:
gr_emp_data.SetSeriesStyle("Salary", &
Foreground!, 0)
This statement sets the background color of the series named Salary in the graph gr_depts in the DataWindow control dw_employees to black:
dw_employees.SetSeriesStyle("gr_depts", &
"Salary", Background!, 0)
These statements in the Clicked event of the graph control gr_product_data coordinate line color between it and the graph gr_sales_data. The script stores the line color for the series under the mouse pointer in the graph gr_product_data in the variable line_color. Then it sets the line color for the series northeast in the graph gr_sales_data to that color:
string SeriesName
integer SeriesNbr, Series_Point
long line_color
grObjectType MouseHit
MouseHit = ObjectAtPointer(SeriesNbr,Series_Point)
IF MouseHit = TypeSeries! THEN
SeriesName = &
gr_product_data.SeriesName(SeriesNbr)
gr_product_data.GetSeriesStyle(SeriesName, &
LineColor!, line_color)
gr_sales_data.SetSeriesStyle("Northeast", &
LineColor!, line_color)
END IF
Specifies the style and width of a series’ lines in a graph.
Graph controls in windows and user objects, and graphs in DataWindow controls objects
controlname.SetSeriesStyle ( { graphcontrol, } seriesname, linestyle,
linewidth )
Argument |
Description |
|---|---|
controlname |
The name of the graph in which you want to set the line style and width of a series, or the name of the DataWindow control containing the graph. |
graphcontrol (DataWindow control only) (optional) |
A string whose value is the name of the graph in the DataWindow control in which you want to set the line style and width. |
seriesname |
A string whose value is the name of the series for which you want to set the line style and width. |
linestyle |
A value of the LineStyle enumerated datatype. Values are:
|
linewidth |
An integer specifying the width of the line in pixels. |
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value is null, SetSeriesStyle returns null.
Data points in a series can have their own style settings. Settings made with SetDataStyle set the style of individual data points and override series settings.

For a graph in a DataWindow, you can specify the appearance of a series in the graph before PowerBuilder draws the graph. To do so, define a user event for pbm_dwngraphcreate and call SetSeriesStyle in the script for that event. The event pbm_dwngraphcreate is triggered just before a graph is created in a DataWindow object.
This statement sets the line style and width for the series named Costs in the graph gr_product_data:
gr_product_data.SetSeriesStyle("Costs", &
Dot!, 5)
Specifies the fill pattern and symbol for data markers in a series.
Graph controls in windows and user objects, and graphs in DataWindow controls
controlname.SetSeriesStyle ( { graphcontrol, } seriesname, enumvalue )
Argument |
Description |
|---|---|
controlname |
The name of the graph in which you want to set the appearance of a series, or the name of the DataWindow control containing the graph. |
graphcontrol (DataWindow control only) (optional) |
A string whose value is the name of the graph in the DataWindow control in which you want to set the appearance. |
seriesname |
A string whose value is the name of the series in which you want to set the appearance. |
enumvalue |
A value of an enumerated datatype specifying an appearance setting for the series. Values for the FillPattern or grSymbolType enumerated datatypes follow. |
To change the fill pattern, use a FillPattern value:
To change the symbol type, use a grSymbolType value:
|
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value is null, SetSeriesStyle returns null.

Using SetSeriesStyle with DirectX 3D Graphs
You cannot use a fill pattern or specify specific symbols
for a series.
This statement sets the symbol used for the series named Costs in the graph gr_product_data to a plus sign:
gr_product_data.SetSeriesStyle("Costs", &
SymbolPlus!)
This statement sets the symbol used for the series named Costs in the graph gr_computers in the DataWindow control dw_equipment to X:
dw_equipment.SetSeriesStyle("gr_computers", &
"Costs", SymbolX!)
Specifies whether a series is an overlay, meaning that the series is represented by a line on top of another graph type.
Graph controls in windows and user objects, and graphs in DataWindow controls
controlname.SetSeriesStyle ( { graphcontrol, } seriesname, overlaystyle )
Argument |
Description |
|---|---|
controlname |
The name of the graph in which you want to set the overlay status of a series, or the name of the DataWindow control containing the graph. |
graphcontrol (DataWindow control only) (optional) |
A string whose value is the name of the graph in the DataWindow control in which you want to set the overlay status. |
seriesname |
A string whose value is the name of the series whose overlay status you want to change. |
overlaystyle |
A boolean value indicating whether you want the series to be an overlay, meaning that the series is shown in front as a line. Set overlaystyle to true to make the specified series an overlay. Set it to false to remove the overlay setting. |
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value is null, SetSeriesStyle returns null.

This statement sets the style of the series named Costs in the graph gr_product_data to overlay:
gr_product_data.SetSeriesStyle("Costs", TRUE)
These statements in the Clicked event of the DataWindow control dw_employees store the style of the series under the pointer in the graph gr_depts in the variable style_type. If the style of the series is overlay (true), the script changes the style to normal (false):
string SeriesName
integer SeriesNbr, Data_Point
boolean overlay_style
grObjectType MouseHit
MouseHit = dw_employees.ObjectAtPointer( &
"gr_depts", SeriesNbr, Data_Point)
IF MouseHit = TypeSeries! THEN
SeriesName = &
dw_employees.SeriesName("gr_depts",SeriesNbr)
dw_employees.GetSeriesStyle("gr_depts", &
SeriesName, overlay_style)
IF overlay_style THEN &
dw_employees.SetSeriesStyle("gr_depts", &
SeriesName, FALSE)
END IF
