Put a limit value on contour and plot3

Hi,

The point of my question is how to put color limit on a specific value on a contour plot or plot3. In fact I would like to have :

• For my contour : if my lines have values from 0 to 10, for exemple I would like to have a specific color for the lines under 5 and a specific color for 5 to 10. Exactly I want to put red color on lines over a limit.
• For my plot3 : I have multiple points on 3D-space and for the z level, I would like to put a limit value and the points that are over this specific z-level takes the red color.

I don't know if I explained my request well but if somebody knows what I mean and have a function that could do that please tell me.

Please explain, what "my lines have values from 0 tp 10" means exactly. Lines do not have values implicitly.

If you post the inputs and the code you have tried so far, suggesting a modification is much easier than with guessing your data and what you exactly want. Please edit the original question to add more details.

I mean it's just the set values for the contour, a line for value 1 to 10 for exemple, so 1 2 3 4 5 6 7 8 9 10, that is set on the contour line.

contour(hanles.X1,handles.Y1,handles.Z1,[0 0.1 0.2 0.3 0.4 0.5 1 2 3 4 5 6 7 8 9],'showtext','on');

For exemple here I have 15 specifics lines and I would like to show the lines that are superior to "5" in Red.

For plot3 you can use the FEX submission https://www.mathworks.com/matlabcentral/fileexchange/5735-plot3c . For contour whould setting the Colormap of the axes work?

Thank's for the function i will give a try with that. Colomap would not solve my problem because I don't want to color the map, I juste want to show in RED the lines thats ares superiors to a specific value.

what do you mean whith FEX submission ?
