Set CartesianChart Grid Unit to be exactly square for 2D Plots (Aspect Ratio)

[stor661]

Background:
A CartesianChart with multiple LineSeries, both Scale at (X,Y) = (0,0), with default UnitWidth. These LineSeries are plotted live and their MinLimits and MaxLimits are adjusted according the max-value of the data being plotted. X-Axis is time [seconds], where each unit width shall be 1 second and Y-Axis is another value of measurement that scales twice that of the X-axis, therefore for each increment of 1-Unit in X-axis, corresponds to an increment of 2-Units in the Y-axis (aspect ratio of 1:2). I defined the Y-axis with "MinStep=2" and X-Axis with "MinStep=1", both axes have "ForceStepToMin = true".

Problem:
I need to know for certain and accurately that each grid unit in the chart grid is perfectly square for my given aspect ratio. TO reiterate, need the grid "squares" to be perfectly square for my (2:1) ratio.

I tried many methods of playing with the Chart parent and Chart child properties, and get the current chart dimentions and substract all corresponding margins/padding (top,bottom, and left, right), and creating a ratio of CartesianChart.Width and CartesianChart.Height, so then adjust the CartesianChart's heigtht and width to have square grid units. But something is not working correctly...I thought playing with the "Customs Separator Intervals" would help, but that also provided no progress.
