Summary: NPlot Pen Error

Initial Comment:

Dear All,

I tried to customize my NPlot step chart in ASP.Net 2.0 to more thick line but changing the Pen.Width property gives an error message:

Changes cannot be made to Pen because permissions are not valid.

The VS.Net designer gives no warning or error message during complication!

Please advise if this is a bug or there is any work-around for that.

Best regards,
Omid

Message:
You're trying to change a property of a readonly Pen instance.

The System.Drawing.Pens.* instances are all readonly instances so you can
only use them as is.

Just do:
npPlot2.Pen = new Pen(Color.DarkBlue, 5);
