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:

One of the links points to the function camzoom, but zoom might be useful also.

I'd prefer the scrollwheel for zooming in and out.

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

I have tried it, but it is not convinient

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.
