How to change labels of contourf when I have no handles?

Hello Everybody,

I have a figure with contourf but lost the data of the figure. I would like to change the labels manually with

clabel(C,h, 'manual','Rotation',0);

but I have no handles C and h. Is it possible to get it somehow with gco or gca? Or can I extract the data and make a new plot? I would prefer option 1 though...

Thanks in advance and best regards

Jan

If the contourf plot is the most recently-plotted object, using get(gca,...) should work. Try this:

contourf(peaks(20),10);

h = get(gca,'children'); 
C = get(h,'contourmatrix'); 
clabel(C,h,'rotation',0)
