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 |

|---|---|
Data point’s colors |
|
Line style and width used by the data point |
|
Fill pattern or symbol for the data point |
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.
For the enumerated datatype values that GetDataStyle stores in linestyle and enumvariable, see SetDataStyle.
Obtains the colors associated with a data point in a graph.

controlname.GetDataStyle ( { graphcontrol, } seriesnumber,
datapointnumber, colortype, colorvariable )
Argument |
Description |
|---|---|
controlname |
The name of the graph for which you want the color of a data point, or the name of the DataWindow control containing the graph. |
graphcontrol (Data Window control only) |
(Optional) When controlname is a DataWindow control, the name of the graph for which you want the color of a data point. |
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 specifying the aspect of the data point for which you want the color. Values are:
|
colorvariable |
A long variable in which you want to store the color. |
Integer. Returns 1 if it succeeds and -1 if an error occurs. Stores a color value in colorvariable. If any argument’s value is null, GetDataStyle returns null.
This example gets the text (foreground) color used for data point 6 in the series named Salary in the 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 = gr_emp_data.FindSeries("Salary")
// Get the color
gr_emp_data.GetDataStyle(SeriesNbr, 6, &
Foreground!, color_nbr)
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)
Obtains the line style and width for a data point in a graph.
Graph controls in windows and user objects, and graphs in DataWindow controls
controlname.GetDataStyle ( { graphcontrol, } seriesnumber,
datapointnumber, linestyle, linewidth )
Argument |
Description |
|---|---|
controlname |
The name of the graph for which you want the line style and width of a data point, 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 the line style and width of a data point. |
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 |
A variable of type LineStyle in which you want to store the line style. |
linewidth |
An integer variable in which you want to store the width of the line. The width is measured in pixels. |
Integer. Returns 1 if it succeeds and -1 if an error occurs. For the specified series and data point, stores its line style in linestyle and the line’s width in linewidth. If any argument’s value is null, GetDataStyle returns null.
For the enumerated datatype values that GetDataStyle will store in linestyle, see SetDataStyle.
This example gets the line style and width of data point 10 in the series named Costs in the graph gr_product_data. It stores the information in the variables line_style and line_width:
integer SeriesNbr, line_width
LineStyle line_style
// Get the number of the series
SeriesNbr = gr_product_data.FindSeries("Costs")
gr_product_data.GetDataStyle(SeriesNbr, 10, &
line_style, line_width)
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, &
6, line_style, line_width)
Obtains the fill pattern or symbol of a data point in a graph.
Graph controls in windows and user objects, and graphs in DataWindow controls
controlname.GetDataStyle ( { graphcontrol, } seriesnumber,
datapointnumber, enumvariable )
Argument |
Description |
|---|---|
controlname |
The name of the graph for which you want the fill pattern or symbol type of a data point, 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 the fill pattern or symbol type of a data point. |
seriesnumber |
The number of the series in which you want the fill pattern or symbol type of a data point. |
datapointnumber |
The number of the data point for which you want the fill pattern or symbol type. |
enumvariable |
The variable in which you want to store the data style. You can specify a FillPattern or grSymbolType variable. The data style information stored will depend on the variable type. |
Integer. Returns 1 if it succeeds and -1 if an error occurs. Stores, according to the type of enumvariable, a value of that enumerated datatype representing the fill pattern or symbol used for the specified data point. If any argument’s value is null, GetDataStyle returns null.
For the enumerated datatype values that GetDataStyle will store in enumvariable, see SetDataStyle.
This example gets the pattern used to fill data point 10 in the series named Costs in the graph gr_product_data. The information is stored in the variable data_pattern:
integer SeriesNbr
FillPattern data_pattern
// Get the number of the series
SeriesNbr = gr_product_data.FindSeries("Costs")
gr_product_data.GetDataStyle(SeriesNbr, 10, &
data_pattern)
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, &
6, data_pattern)
These statements store in the variable symbol_type the symbol of data point 10 in the series named Costs in the graph gr_product_data:
integer SeriesNbr
grSymbolType symbol_type
// Get the number of the series
SeriesNbr = gr_product_data.FindSeries("Costs")
gr_product_data.GetDataStyle(SeriesNbr, 10, &
symbol_type)
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:
integer SeriesNbr
grSymbolType symbol_type
// Get the number of the series
SeriesNbr = dw_employees.FindSeries("gr_depts", &
sle_series.Text)
// Get the symbol
dw_employees.GetDataStyle("gr_depts", SeriesNbr, &
6, symbol_type)
