When I hide a curve via the code :
myQCPGraph-> setVisible (false);
I also hide the associated item in the legend of the QCP via the code:
myQCP-> legend-> itemWithPlottable (myQCPGraph) -> setVisible (false);
Thanks to these two instructions, I have my curve that hides, just like its associated element in the legend of the QCP.
However, I note that the size of the legend does not change. Is there a way to automatically resize the legend size? Indeed, when I hide an element, the legend contains an empty white space. So I'm looking for a way to reduce its size.
My research in the documentation and on the forum were unsuccessful.
Thanks for your help.
