wadewei Hi everyone, Is there a way to add a line on the 2d plots generated by plotmodel() marking values of zero? Thank you! Wade
mathieumorlighem Hi Wade If you want to add a zero contour you can use the option 'contourlevels',{0} I hope this helps Mathieu
wadewei mathieumorlighem Thanks Mathieu. It turns out I used the correct option. However the default color for lines drawn through 'contourlevel' happens to coincide with the filling color of zero. Changing either of them solves the problem.
