plotting 4 interdependent graphs in 1

What I see in the picture is a basic X,Y scatter chart with multiple data series. If I understand the axis labels, the positive x axis displays the ratio of L/H, the positive y axis shows the ratio of wL/wH, the negative x axis shows the ration of Px/Py, and the negative y axis shows the ratio of Qx/Qy.

The chart itself is not going to handle the computations needed, so you will need to program them into the spreadsheet. It is not clear to me exactly what these computations should look like, but I would expect to see several x,y sets of data in the spreadsheet. With the desired ratios/values calculated in the spreadsheet, it should be a simple (if tedious) matter of creating the scatter chart and adding each data series (I usually prefer to use the "select data" dialog for this step.
