Axis break in graphs

After the last update to the latest version (went smooth, thanks a lot!) I noticed that graphs are not having an axis break, ie. they all show a full y-axis scale starting at 0 to the values measured. I remember vaguely that this was not the case before.
See below for an examples without and with axis break.
As you can see the axis break allows to clearly see what is going on. But that might be a personal opinion, so would it be hard to show graphs with axis break as an optional (global) configuration item?

I think this change has caused this

You can play with the file www/app/log/RefreshingChart.js to change the behavior as you do not have to build anything.

Thanks! Reverting line 85 in www/app/log/RefreshingChart.js returns the broken axis view again.
The change (git sha f0cff38a70) was added recently on May 25th by GizMoCuz with message: 'Default area graph type for most day charts'.
Not sure which problem this fixes?
It is using boolean flag `isShortLogChart` for CounterLogChart that has been in since 2020.

Are you the same person who created a Github issue?
Maybe an idea to mention this forum thread there?
The idea was to make a area spline as it looks better, but it should NOT start at zero indeed.
Could you make a PR to fix this? (keeping the area spline type!)
