|---|---|
|
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 that identifies the series in which you want to set the transparency value of a data point. |
|
datapoint |
The number of the data point for which you want to set a transparency value. |
|
transparency |
Integer value for percent transparency. A value of 0 means that the data point is opaque and a value of 100 means that it is completely transparent. |

Examples
These statements set the transparency percentage to 50% for data point 3 in the series named Costs in the graph gr_1 in the DataWindow control dw_employee:
integer SeriesNbr, ItemNbr, TransNbr
grObjectType clickedtype
// Get the number of the series and datapoint
clickedtype = this.ObjectAtPointer("gr_1", &
SeriesNbr, ItemNbr)
//The following statement sets Transparency to 50%
TransNbr = 50
dw_employee.SetDataTransparency("gr_1", &
SeriesNbr, ItemNbr, TransNbr)See also
