50% contour line in plots

Question:
Do we desire 50% of max, or 50% of each slice?

If max, it is easy to put a single ax.contour(ch.max()/2)

If slice wise how do we wish to compute:

• go to the max step away in each direction until below half, linearly interpolate between consecutive points
• Fit to a function, use the half max from there
• ignore slices which have noise levels > 50% of their max
• normalize along the x-axis, and call ax.contour(0.5)
• something else I hadn't thought of yet?

I vote we do both 50% of max and 50% of slice with different colors of contours. I think the "normalize along the x-axis, and call ax.contour(0.5)" option is good for slices.
