error when using clabel(C,h)

when I use clabel as follow:

>> [X,Y] = meshgrid(-2:.2:2,-2:.2:3);
Z = X.*exp(-X.^2-Y.^2);
>> [C,h] = contour(X,Y,Z);
>> clabel(C,h)

It gives me an error: Error using clabel (line 77) Not enough contour handles. Can anyone tell me how to fix it?

Your code runs for me without error in R2018a. I cannot reproduce the problem.

Maybe you have closed your figure window before executing clabel(C,h).

Had the same problem, fixed it!

Thanks.

Hi guys,

I have the same problem and I'm using the latest Matlab version R2018a. I am actually using the clabel(C,h,v) command with v being the vector of labels that I want. Here is my minimum working example:

[C,h]=contourfm (lat, lon, data);
 v = [0:2:50]; 
 clabel (C, h, v);

I also tried clabel(C, v, Name, Value) options and it gives the same error;

Once the figure is plotted, I do clear C and h because I'm using them in the next figure. That shouldn't be a problem though (or is it?) because it happens quite a few lines after the clabel command.

Thanks for your help!
