Graph

When I change from metric to British units (which is what I want displayed), the graph panel shows the data compressed along the x-axis. (When it is metric, it is evenly spread across the area of the graph.) When BU is set, I have been right-clicking on the graph and using “Set manual scale” to change the range on the x-axis but it won’t stick. Alternately, when I try “Autoscale”, nothing happens at all. If I reload the data, it reverts to the data being compressed along the x-axis in BU.

Does anyone know how to use autoscale to change the x-axis scale and save it?
