I have bit of code that draws nice line charts in ZedGraph.
I can not change the code entirely, but I would like to have some of the lines not have a y value for each point on the x-axis.
I can do this in Excel, but I don't know how to in ZedGraph.
I create graph with .AddCurve.
How do I do this?
NaN values should do the trick.
If you want to break the line for example between x=1 and x=2, just add a point (1.5, double.NaN). Zedgraph should make the gap by itself.
