Great application.

I am not sure if this is the right place, my problem is with ZedGraph.

I am using ZedGraph because I want a log log plot and it works well

Looking in the forum it would seem my problem has been a problem with 2D but it is fixed.

Issues arise when you put logical functions in the function definition.

For example the PLOT DOMAIN function given in the WIKI does not work with ZedGraph.

Kind Regards

This is certainly true if you have no document !

Can I upload a sample document? I can't see how to do it.

Make it simple like this:
1. start a new thread typical: Solving DE
2. now, you see the paper clip in the top
2. click on paper clip, add file
3. browse your file, double click, upload new file, post

thanks
