Multi Y-axis Cartesian chart panning ends with changed y-axis range

[ajschooneveld]

Describe the bug
After panning a multi Y-axis Cartesian chart, one of the y-axis is changed unintensionally.

A Carteisan chart with DateTimePoints and 1 x axes and 2 yaxis and ZoomMode=Both. The line series and axis use binding to the view model.
One y-axis has MinLimit=-1 and Maxlimit=3, the other axis has MinLimit = -3 and MaxLimit=1.

To Reproduce
Steps to reproduce the behavior:

1. Create sine waves between -1 and 1 for both line series.
2. Set the MinLimit and MaxLimit of the axes as described above. You see 2 sine waves one above the other.
3. Start panning with the mouse. The sine waves move as expected.
4. Release the mouse button. The two sine waves are drawn at the same position instead of one above the other. You can see one of the y axes ranges has changed, although the MinLimit and MaxLimit haven't been changed by the program.

Expected behavior
Two sine waves are shown one above the other.

Screenshots
Before and during panning:

After panning, one axis has changed:

Hi, thanks for sharing the zip! I held off until rc-6 was released, since this version offers significantly improved zooming and panning support.

Your example will work out of the box if you disable data-fitting in your chart:

<lvc:CartesianChart ZoomMode="Both,NoFit"/>

With the new NoFit feature, you can freely pan and zoom the chart without the library auto-fitting the axes to the data. For your scenario, that behavior seems more appropriate—otherwise, the axes would constantly adjust to fit the visible data range.

I will close this for now, but feel free to reply or create a new issue if the problem is not fixed.
