bqplot: PanZoom does not work with pandas datetime data - x-axis overzooms

Trying to panzoom a linechart generated with the attached csv file. When using the zoom function, the x-axis (DateScale) goes completely off, making this feature unusable. For one click in the wheel, the scale changes by more than 5 hours. I was expecting changes in the order of minutes. Attached is a reference notebook implementation showing the problem. bqplot_panzoom_issue.zip You will need to change your file path to import the data, currently set to: file_path = '~/work/FCMC_10Hz_simple.csv'

This is the data file: FCMC_10Hz_simple.zip

The last cell is my current, inelegant, workaround, where I need to plot my data against numeric index instead of its true time stamp.

Could you look into this? I could not find what the problem is. I tried to set the min= during my DateScale declaration, but that did not help either.

Help is much appreciated.

Tks.
