Finds out the appearance of a data point in a graph. Each data point in a series can have individual appearance settings. There are different syntaxes, depending on what settings you want to check.
|
To get the |
Use |
|---|---|
|
Data point's colors (called GetDataStyleColor in JavaScript) |
|
|
Line style and width used by the data point (called GetDataStyleLine in JavaScript) |
|
|
Fill pattern for the data point (called GetDataStyleFill in JavaScript) |
|
|
Symbol for the data point (called GetDataStyleSymbol in JavaScript) |
GetDataStyle provides information about a single data point. The series to which the data point belongs has its own style settings. In general, the style values for the data point are the same as its series' settings. Use SetDataStyle to change the style values for individual data points. Use GetSeriesStyle and SetSeriesStyle to get and set style information for the series.
The graph stores style information for properties that do not apply to the current graph type. For example, you can find out the fill pattern for a data point or a series in a 2-dimensional line graph, but that fill pattern will not be visible.
Description
Obtains the colors associated with a data point in a graph.
Applies to
PowerBuilder DataWindow
DataWindow control
Syntax
PowerBuilder
integer dwcontrol.GetDataStyle ( string graphcontrol, integer seriesnumber, integer datapointnumber, grColorType colortype, REF long colorvariable )
|
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 the color of a data point. |
|
datapointnumber |
The number of the data point for which you want the color. |
|
colortype |
A value of the grColorType enumerated datatype (in PowerBuilder) or an integer (in JavaScript) specifying the aspect of the data point for which you want the color. For a list of values, see grColorType. |
|
colorvariable |
In PowerBuilder, a long variable in which you want to store the color. |
Return value
Returns 1 if it succeeds and -1 if an error occurs. In PowerBuilder, GetDataStyle stores an RGB color value in colorvariable. If any argument's value is null, GetDataStyle returns null.
Examples
This example gets the background color used for data point 6 in the series entered in the SingleLineEdit sle_series in the DataWindow graph gr_emp_data. It stores the color value in the variable color_nbr:
long color_nbr
integer SeriesNbr
// Get the number of the series
SeriesNbr = &
FindSeries("gr_emp_data", sle_series.Text)
// Get the color
dw_emp_data.GetDataStyle("gr_emp_data", &
SeriesNbr, 6, Background!, color_nbr)See also
Description
Obtains the line style and width for a data point in a graph.
Applies to
PowerBuilder DataWindow
DataWindow control
Syntax
PowerBuilder
integer dwcontrol.GetDataStyle ( string graphcontrol, integer seriesnumber, integer datapointnumber, REF LineStyle linestyle, REF 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 the line style and width of a data point. |
|
datapointnumber |
The number of the data point for which you want the line style and width. |
|
linestyle |
In PowerBuilder, a variable of type LineStyle in which you want to store the line style. For a list of line style values, see LineStyle. |
|
linewidth |
In PowerBuilder, an integer variable in which you want to store the width of the line. The width is measured in pixels. |
Return value
Returns 1 if it succeeds and -1 if an error occurs. In PowerBuilder, for the specified series and data point, GetDataStyle stores its line style in linestyle and the line's width in linewidth. If any argument's value is null, GetDataStyle returns null.
Examples
This example gets the line style and width for data point 6 in the series entered in the SingleLineEdit sle_series in the graph gr_depts in the DataWindow control dw_employees. The information is stored in the variables line_style and line_width:
integer SeriesNbr, line_width
LineStyle line_style
// Get the number of the series
SeriesNbr = dw_employees.FindSeries( &
"gr_depts", sle_series.Text)
// Get the line style and width
dw_employees.GetDataStyle("gr_depts", SeriesNbr, &

Description
Obtains the fill pattern of a data point in a graph.
Applies to
PowerBuilder DataWindow
DataWindow control
Syntax
PowerBuilder
integer dwcontrol.GetDataStyle ( string graphcontrol, integer seriesnumber, integer datapointnumber, REF FillPattern fillvariable )
|
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 the fill pattern of a data point. |
|
datapointnumber |
The number of the data point for which you want the fill pattern. |
|
fillvariable |
In PowerBuilder, a variable of type FillPattern in which you want to store the fill pattern value. For a list of values, see FillPattern. |
Return value
Returns 1 if it succeeds and -1 if an error occurs. In PowerBuilder, GetDataStyle stores a value of the FillPattern enumerated datatype representing the fill pattern used for the specified data point. If any argument's value is null, GetDataStyle returns null.
Examples
This example gets the pattern used to fill data point 6 in the series entered in the SingleLineEdit sle_series in the graph gr_depts in the DataWindow control dw_employees. The information is assigned to the variable data_pattern:
integer SeriesNbr
FillPattern data_pattern
// Get the number of the series
SeriesNbr = dw_employees.FindSeries("gr_depts", &
sle_series.Text)
// Get the pattern
dw_employees.GetDataStyle("gr_depts", SeriesNbr, &

Examples
These statements store the symbol for a data point in the variable symbol_type. The data point is the sixth point in the series named in the SingleLineEdit sle_series in the graph gr_depts in the DataWindow control dw_employees:

// Get the number of the series
SeriesNbr = dw_employees.FindSeries("gr_depts", &
