Two-dimensional zooming

[Philipp U]

As I got a really helpful and quick response with another issue, I wanted to give it a try with another problem.

Is there a built-in configuration for two-dimensional zooming i.e. picking with your mouse the rectangle, that should be shown?

I found an example online, but i can't make it work with my application. I guess it only works with older versions of dygraphs.

Maybe there are some attributes or configurations built in to achieve it in a simpler way I fail to find?

Alright, drawing a zoom rectangle was easier than expected.

Could you give me a clue what has to be adapted that the zooming is limited to the choosen rectangle?

I tried to modifiy the code but it keeps zooming either in x or y direction.

Fixed the issue myself.

Actually also quite easy but problems with testing blocked me a bit.

For others that may encounter the problem:

I adapted drawZoomRext_ and endZoom
