Description

check if Curve is in a graph layer and return its plot index if true

Syntax

int curve_in_layer_get_index( const curvebase & cuv, const GraphLayer & gl )

Parameters

cuv: [input] Curve to test
gl: [input] graph layer to test

Return

plot index if in layer, or -1 if not

Examples

EX1

//This example return the index of the specified column in all Graphs in current folder.
void curve_in_layer_get_index_ex1()
{
    Worksheet wks = Project.ActiveLayer();
    if(!wks)

    Curve crv(wks, 1);
    Folder fld = wks.GetPage().GetFolder();
    //go through all pages in folder to check GraphPage
    foreach(PageBase page in fld.Pages) 
    {

            int nIndex = curve_in_layer_get_index(crv, gl);
            //if curve is in the layer, output some information such as:curve name, graph name, and index.
