Additional text on contour lines

Hi,

I have a contour and want to add some specific text on one of the contour lines.

For example:

------------------------------------

Z = magic(4);

[C,h] = contour(interp2(Z,4));

h = clabel(C,h);

set(h,'BackgroundColor',[1 1 .6],'Edgecolor',[.7 .7 .7])

------------------------------------

How can I add a text on the line with label 8 in the plot - for example, 'Margin'.

Try using the CLABEL function to get the text object handles and then set the text object "String" property to the text you want. Something like this:

[C,h] = contour(peaks(20),3);
th = clabel(C,h);
set(findobj(th,'String','0.59778'),'String','Base Line')

where '0.59778' is the numeric label of the line whose label you want to change and 'Base Line' is the label you want that line to use.

Hello, I think the string property has been removed from MATLAB R2017b. How do I add string labels to my contours now? Thanks!
