I would like to produce a linear regression scatter plot to compare two series of data that, ideally, would be equivalent (such as experimental value versus theory). To avoid distorting the axis, I wish for both axis to have the same dimensions - a square is a square. However, even when I make the width and height of both the chart and chart area equal dimensions, 10 units on one axis is not quite the same number of pixels as 10 units on the perpendicular axis.

Can a perfectly square axis plot be achieved in Calc?
