GetDataPieExplode

Description

Reports the percentage of the pie graph’s radius that a pie slice is exploded. An exploded slice is moved away from the center of the pie in order to draw attention to the data.

Applies to

Graph controls in windows and user objects, and graphs in DataWindow controls

Syntax

controlname.GetDataPieExplode ( { graphcontrol, } series, datapoint,
  percentage )

Argument	Description
controlname	The name of the graph for which you want the percentage a pie slice is exploded, 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 percentage a pie slice is exploded
series	The number that identifies the series
datapoint	The number of the exploded data point (that is, the pie slice)
percentage	An integer variable in which you want to store the percentage of the graph’s radius that the pie slice is exploded

Returns

Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value is null, GetDataPieExplode returns null.

Examples

Example 1

This example reports the percentage that a pie slice is exploded when the user clicks on that slice. The code checks whether the graph is a pie graph using the property Graphite. It then finds out whether the user clicked on a pie slice by checking the series and data point values set by ObjectAtPointer. The script is for the DoubleClicked event of a graph object:

integer series, datapoint

grObjectType clickedtype

integer percentage

percentage = 50

IF (This.GraphType <> PieGraph! and &

    This.GraphType <> Pie3D!) THEN RETURN

clickedtype = This.ObjectAtPointer(series, &

    datapoint)

IF (series > 0 and datapoint > 0) THEN

    This.GetDataPieExplode(series, datapoint, &

    percentage)

    MessageBox("Explosion Percentage", &

      "Data point " + This.CategoryName(datapoint) &

      + " in series " + This.SeriesName(series) &

      + " is exploded " + String(percentage) + "%")
