  • Added methods to zoom the plot programmatically, to match the previously added translate_bounds().
  • Added an example of how this method can be used to customize the plot navigation.

Closes #1164.

Just need to figure out why the zoom doesn't work until you have scrolled at least once (trying to understand the new plot logic, as it changed a lot from when this PR was opened) (fixed). And then see if it would be better to move the example to the demo app instead, so it's easier to test for web as well.

I am also interested in this feature.
Is there anything blocking this apart from missing labels?

@YgorSouza
Add methods to zoom the plot manually

So you can bind different keyboard/mouse gestures to it, lock the X or Y
axis, customize the zoom speed etc.

Also interested in this!

My usecase is manipulating a video preview:

thermal_zoom.mp4

I'd like to zoom in-out without using ctrl, because scrolling the preview up and down makes little sense.
