I need the ZedGraph plot a line Chart.
I am getting the data from serial port and sending to the ZedGraph.
To see the plot, must use the Set Scale to Default.
How to display the graph?

I was trying to compile your code.

   But I guess, I'm missing all of these:

          id01_02 = lbl_id01_02mm.Text;
            id02_02 = lbl_id02_02mm.Text;
            id03_02 = lbl_id03_02mm.Text;
            id04_02 = lbl_id04_02mm.Text;
            id05_02 = lbl_id05_02mm.Text;
            id06_02 = lbl_id06_02mm.Text;

I went through thuis simple example :
http://quantcsharp.webs.com/howtousezedgraph.htm
and it worked easily for me

But with your code I still cannot understand how you are getting the Y data, etc.

Thanks a lot, I saw the code in another question, I'll certainly look at it, when I have a little bit of time, and if I'm lucky
might even be of some help. I'll let you know in any case.
