Hello community,
I've got a GUI with controls and axes. I need to zoom in and out my axes after plotting. I want to do this with pushing mouse button. Any idea how can I do this?
Thanks in advance.
Best regards,
Andrew

I suggest to search in the internet at first, because you will find a lot of existing solutions:
https://www.google.de/search?q=Matlab+zoom
One of the links points to the function camzoom, but zoom might be useful also.

I use a slider with a text label that has the current zoom. See this link for my code.

If clicking the mouse button on a slider is too inconvenient, what could be more convenient? Clicking on the image? Is that more convenient? If so, then you'll have to make a callback for the mouse button down event.
