2.2.4.16.4 GetGraphPoints::GetData

GetData

Description

Gets the XY points into two vectors for the points that have been picked thus far. Can be called from within an event method of a derived class or after the GetGraphPoints::GetPoints() has returned. Optionally returns the row indices of the points from the plot source data sheet and/or the zero-based plot indices for the picked points.

Syntax

int GetData(vector& vx, vector& vy = NULL, vector<int>& vnDatapointIndices = NULL, vector<int>& vnDataplotIndices = NULL);

Parameters

vx

[output] Receives the x-values of the selected points.

vy

[output] If not NULL, receives the y-values of the selected points.

vnDatapointIndices

[output] When not NULL it receives the zero-based row index of data from the source data sheet. If 1st parameter of GetGraphPoints::SetFollowData() is false, the returned values will all be -1.

vnDataplotIndices

[output] When not NULL it receives the zero-based index of the plot in the graph layer. If 1st parameter of GetGraphPoints::SetFollowData() is false, the returned values will all be -1.

Return

Returns -1 if cancelled or an error occurred. Otherwise returns number of points picked.

Examples

For an example of using this method, please see the Example Section in GetGraphPoints.
