Thanks, Easwar. It works. But I really do not like programming in Origin C as a lot of commands have to be memorized and actually most users are just users, not interested in or familiar with embedded programing, never mentioning having time to learn programming.

I appreciate your help.

How to smooth all curves simultaneous using adjacent averaging.??

---

void SmoothMultiCurve()
{
	Layer lyAct=Project.ActiveLayer();
	GraphPage gpAct=lyAct.GetPage();
	if (!gpAct) return;
	
	foreach(GraphLayer gl in gpAct.Layers )
	{
			int iIndex=0;
			DataPlot dp;
			
			do
			{
				dp = gl.DataPlots(++iIndex);

				if (dp)
				{
					Curve cc(dp);
				 	smooth(cc);
				}
				
			} while(dp);
			
	}
}
