How To Put String Labels on Contours for Contour Plots in MATLAB

Question

I am wondering if it is possible to label the contours of a MATLAB contour plot with a set of user-defined strings?

I am currently using the following code snipper t

Answer 1

In this case, hcl is actually an array which stores handles to every contour label on your plot. When you set properties using the array (as in your code),

set(hcl, 'name', 'value')

You will set the property of every label to the same value.

You can change the properties of individual labels by iterating over the array. For example, this is how you would add a percentage sign:

for i = 1:length(hcl)
    oldLabelText = get(hcl(i), 'String');
    percentage = str2double(oldLabelText)*100;
    newLabelText = [num2str(percentage) ' %'];
    set(hcl(i), 'String', newLabelText);
end
