Examples

EX1 

//Change the display range of the data plots in the graph layer to show only points from 3 to 5.
/*Run following LT command before run the code
fn$= system.path.program$ + "Samples\Graphing\Group.dat";
impASC fn$; 
worksheet -s 2 0 4 0;
plotxy;
*/
void    GraphLayer_DataPlots_ex1()
{
    GraphLayer gl = Project.ActiveLayer();       
 
    // Loop over all the dataplots in the collection:    
    foreach (DataPlot dp in gl.DataPlots)
    {
        // Change the display range of the data plot to show only points from 3 to 5:
        dp.SetRange(3, 5);
