Zoom is lost when graph refresh

[arsenicks]

it's all in the title, it would be nice to stop refreshing when zoomed in, or better refresh but keep the zoom as it is!

Hmmm... that's a great point @arsenicks. I'll do some googling and check on workarounds. I think the problem is that the way app refreshes work in Dash apps is by refreshing the function that constructs the layout, so whenever that happens, the zoom is also reset.

#24 should fix this, by adding the freeze button

This has now been fixed thanks to new improvements. Shout-out to @theimo1221 for the great freeze button. FYI @theimo1221 if you have a second, could you include a 1 or 2 line comment near the button that explains what the javascript is doing there? I'm not great at java and think most folks visiting this project will by primarily Python-literate, so that would help them a bunch.
