Description
Determines whether the data at a given data point is labeled in a DirectX 3D graph.
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)
