Does anybody know any way to increase or decrease the number of displayed curvature graphs?

See image below - I’m matching a single span surface of degree 5 (in the middle of the image) to larger/more simple surfaces either side of it.

At the moment I’m getting 3 graphs but want to tweak the surface by each control point row. So it’d be ideal to have 6 graphs at equal spacing which would be close enough to the control point rows to allow me to see what’s going on as I tweak.
