Description

Find data points inside polygon enclosed by vX, vY, only supported by single XYRange.

Syntax

int GetIndices( vector<int> & vIndicies, const vector & vX, const vector & vY )

Parameters

vIndicies: [output]
vX: [input] polygon to find points inside
vY: [input] polygon to find points inside

Return

Return the size of vIndices.

Examples

//Find data polygon enclosed by vX and vY.
void DataRange_GetIndices_Ex1()
{
        //assume the active workbooka sheet and has least two columns before run this code.
        Worksheet wks = Project.ActiveLayer();
        if ( !wks )
        {
                printf("Can not find any active worksheet!");
                return;
        }
        DataRange dr;
        dr.Create();//init the object
        dr.Add("X", wks, 0, 0, -1, 0);
        dr.Add("Y", wks, 0, 1, -1, 1);
        
        vector vX, vY;
        vX.Uniform(20, 1);//generate random data
        vY.Uniform(20, 4);
        
        vector<int> vIndices;
        dr.GetIndices(vIndices, vX, vY);
        return;
