Description
Determines whether the data at a given data point is labeled in a DirectX 3D graph.
Note
This function is obsolete. It is supported only for DirectX 3D graph rendering and is retained for backward compatibility. This function is not recommended for new development.
Applies to
Graph controls in windows and user objects, and graphs in DataWindow controls
Syntax
controlname.GetDataLabelling ({graphcontrol,} series, datapoint, value)
|
Argument |
Description |
|---|---|
|
controlname |
The name of the graph from which you want data, 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. |
|
seriesnumber |
The number that identifies the series for which you want the data label setting. |
|
datapoint |
The data point for which you want to obtain a label. |
|
value |
A boolean passed by reference that indicates whether the data point has a label. |
Return value
Returns 1 if it succeeds and -1 if an error occurs. If any argument's value is null, GetDataLabelling returns null.
Usage
GetDataLabelling determines whether a data label is set for data points from DirectX 3D Area, Bar, Col, or Line graphs. You cannot use this method with DirectX 3D Pie graphs.
Examples
In a DataWindow Clicked event, these statements obtain the number of the series and data point clicked by the user in gr_1 and determine whether the label is set for that data point.
integer SeriesNbr, ItemNbr
boolean refB
grObjectType clickedtype
clickedtype = this.ObjectAtPointer("gr_1", &
SeriesNbr, ItemNbr)
this.GetDataLabelling("gr_1", SeriesNbr, &
ItemNbr, refB) These statements obtain the number of the series and data point clicked by the user in a graph object and determine whether the label is set for that data point.
integer SeriesNbr, ItemNbr boolean refB grObjectType clickedtype clickedtype = this.ObjectAtPointer(SeriesNbr, ItemNbr) this.GetDataLabelling(SeriesNbr, ItemNbr, refB)
