reset button of zoom in "drag" mode is not worked properly after load() new data

[monexiao]

Description

In "drag" zoom mode, the reset button will unzoom the graph to default settings.
If I use chart.load() to load new data, the and drag to zoom, and then click reset button, the unzoom() will show previous data range, not new data range.

Steps to check or reproduce

I use timeseries data, for example:

1. Load 8hr data with 1data/6min.
2. Drag any region to zoom.
3. Click reset button to unzoom, the chart shows 8hr data.
4. Load 1 day data to replace. (should unzoom to hidden the old reset button otherwise the old one still show but it is not work.)
5. Drag any region to zoom.
   6. click reset button to unzoom, the chart show 8hr data, but actually total data is 1day data.

Hi @monexiao, please provide reproducible online fiddle for the check.

After checking, I found the phonmenon occurs when the zoom option rescale is set as true.
Like as the issue I post previously.

The rescale option will cause the zoom function work improperly.
