Multiple X-Axis support with mvXAxis, mvXAxis2, mvXAxis3

[foodfo]

I noticed in the demo that there is (unofficial?) support for multiple X axes on a single plot. This is awesome functionality but I can't find any documentation on it. Wondering if anyone knows the status of this feature or how it works in detail.
From my testing, the additional X-axes will always try to pair with their matching Y axis (mvXAxis2 -> mvYAxis2 even if mvYAxis3 exists) or their next highest sibling that exists (mvXAxis3 -> mvYAxis2 if mvYAxis3 does not exist. I am unable to pair a mvXAxis3 with a mvYAxis1 if any other mvYAxis exists, and it seems to be possible to plot the data even if mvYAxis does not exist at all (mvPlot appears to always build an x container even if it isn't declared explicitly)
Does anyone know more about this feature? I'm hoping it is possible to remap the axis assignments after creation in order to override the default mapping.

Hi. If you have a base code about it, please share to know more about the situation that you mentioned.
So, you can find some details about the multiple axis implementation on the demo code: https://github.com/hoffstadt/DearPyGui/blob/master/dearpygui%2Fdemo.py
