Bug in custom time format example when zoom-in

[Piyush3dB]

In the custom-time-format example, there appears to be a bug in that the zoom does not work correctly.

Attached a GIF showing this.

Any pointers as to the problem? I could try and fix it myself if given some hints where to look in the code.

Beat Regards!

I just encountered the same issue.

It looks like the issue is in the box-select for zooming. After some level of zoom, it seemingly stops accepting inputs.

If I manually call chart.zoomX([val1,val2]) from the developer console, it will zoom in to any arbitrary level without issue, so this should be a relatively simple issue with the box select logic.
