Image History dock versus Image History panel

Description

The star graphs in the Image History docking module and Image History details panel are quite different. See the attached picture.
The docking module shows wide swings in the number of stars which makes me believe the number of stars has drastically changed. The line in the panel doesn’t change much when the number of stars is relatively flat.

Useful Info

I have seen this in prior versions as well.

OS: Windows 10
Ver: 4.0.0.680

I think this is not an error just a matter of different scales for the vertical axis. The HFR graph in the “big” history module is quite useless because of the scale that unfortunately can not be adjusted by the user.
