Allow zoom with right-click drag

[clemisch]

What's the intended way to zoom a plot "anisotropically" in silx view? I can only zoom isotropically with the mouse wheel.

In silx view I would expect to zoom with right-click+drag when the "movement button" is selected. Instead, right click opens the "zoom back" dialogue.

In a normal matplotlib figure window I can zoom freely with right-click+draw. The "zoom back" function is the home button, which unfortunately doesn't exist in silx view.

I can imagine you are very hesitant to change established GUI elements in silx, but I really miss the right-click+drag zoom (but constantly try by mistake).

Currently, you can select axes to zoom in the drop-down menu of the zoom icon. This impacts both the zoom tool and the "zoom on wheel". This is cumbersome to change but it is already there:

I agree with you it would be nice to have a simpler way to do so, either as in matplotlib or as in h5web:

Thanks! I was not aware of that feature. It's (subjectively!) not ideal but already an improvement.

I agree!
It was made primarily for the zoom selection, not for zoom on wheel or zoom by drag.
I'm sure we can find a better way.
