[Chart] Equal scale on both axes

[Tim Docker]

Hi,

Welcome to the list.

There is currently no way to lock the aspect ratio in this way.

Setting the chart size sets the outputs size of the canvas. This includes
not just the plot area, but also the title, axis labels, legend, etc.

I think you will have to this manually, by choosing the aspect ratio of the
output image by setting its size, and then manually setting the range for
each axis to give you the desired aspect ratio in plot coordinates.

Cheers,

Tim
