Option for equally sized axes in CartesianChart

[mrericrichter]

When showing a Cartesian chart of x and y values, I would like to have the option to set the same axis-to-screen ratio for both axes x and y. This is especially required if data contains physical extensions such as the width and length of an object. If the axes are not equally sized, these objects get distorted.

Example with differently sized axes and with distorted object extensions (the red rectangle should be extended to the right):

Example with equally sized axes and correct object extensions:

Current workaround: Derive from CartesianChart, register to the 'Measuring' event, and reset one of the axes:

public class CartesianChartAxisEqual : CartesianChart
{
    public CartesianChartAxisEqual()
    {
        Measuring += context => 
        {
            var xAxis = XAxes.First();
            var yAxis = YAxes.First();

            var axisLengthXPixels = context.ControlSize.Width;
            var axisLengthYPixels = context.ControlSize.Height;

            // (ymax - ymin) / (xmax - xmin) = axisLengthYPixels / axisLengthXPixels
            var newYMaxLimit = axisLengthYPixels/ axisLengthXPixels * (xAxis.MaxLimit - xAxis.MinLimit) + yAxis.MinLimit;
            var yMaxLimitDiff = newYMaxLimit - yAxis.MaxLimit;
            var yMaxLimitDelta = yMaxLimitDiff / 2;
            yAxis.MaxLimit += yMaxLimitDelta;
            yAxis.MinLimit -= yMaxLimitDelta; 
        };
    }
}

As a reference, there are such options in other chart APIs, e.g. 'axes equal' in Matlab, or 'PlotType = PlotType.Cartesian' in oxyplot.

There might be several ways to auto-resize one of the axes (and which one), so adding an example to the docs might be a good idea.
