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. |

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
