I'm looking for a tool that works in a similar way to Matlab's brush tool.
I graph a spectrogram of a signal, i.e. a 2D array, using imagesc. In this spectrogram I would like to manually mark a certain area and extract the data within this area. For this purpose I tried to use Matlab's brush tool. But obviously it doesn't work for imagesc-figures. Can you help me and suggest solutions? Is there another tool from Matlab that works for imagesc-figures?
Thanks for your help.
