more on: yaxis.stubformat and low variance data
- After some more investigating it is the inc auto which us wrong
yaxis.stubs: inc auto
It is fixed by setting
yaxis.stubs: inc 1
but in order to find it I need to scan all columns to find max min,
I need to find which axis it aplies to and find the total max-min
for all columns to be plotted on that axis.
