How to calculate and show zonal statistics CATIA?

[Sacaq]

Hi~
I am new in using CATIA.
I would like to have a zonal statistic about mean curvature on a surface, as attached file.
I have tried Surface Curvature Analysis, but the result is smooth and not like the attached file.
I don't know what to do. Can you help me?
Thank you!

These values are curvature radius.

First, I tried to make an array of splines on the surface.
The spline pattern looks like mesh lines.
Then, make points from the intersections of splines.
Then, calculate curvature radius on each points along the two splines through the point.
Thus, there are two curvature radii on each point.

However, I don't know how to plot the figure like the attached file.
