Hi,
I am new to DPLOT, and was wondering is there a way to just integrate the area between two crossing curves?
I have tried using intergrate button, however the entire area is calcuted, I only need the area between two specific point on the X- axis. I have read through the forum on where people asking similar question are instructed to use the integrate() , how is that function utilized? (I'm also new to coding).

Thanks

I can't think of a good way to do that. About the only way would be to delete all the points in curve 1 before the intersection, delete all points in curve 2 after the intersection, combine the two results with Edit>Combine Curves, then use the Integrate command.
