Yeray,

Your code worked very successfully. Now how do I revise it to plot six curves on the same chart, and how do I make the curve line (pen) width larger. I have tried looking at all of the properties associated with TChart and cannot find any thing that ties to Series and width. I was also unable to simply add additional ADDXY statements onto the executable.

Thank you in advance for any help you can provide. John Shyer

Hello John,

For future reference, find Part One [here|https://forums.embarcadero.com//thread.jspa?threadID=157226&tstart=0] .

I'm not sure to understand the problem. The code I posted in the "Part One" already plots six series in the same chart.

Have you tried with the Pen.Width property?
Ie, being Series1 an instance of TLineSeries:

 
Series1.Pen.Width:=value;


The same for the AddXY method. It's a method of the series. Ie:

 
Series1.AddXY(x, y);


May I suggest you to check the Tutorials here and the Features Demo ("TeeChart compiled demo") here.
