Add scaling for high-value stats in graphs

[mermakov]

Hello,

When you enable total scrap/score trackers along with hull/crew quantity, the overall graph becomes seriously unbalanced since all these stats share Y-axis, but have different usual ranges. I think it would be reasonable to apply some scaling (logarithmic?) for these stats or simply disallow both at once.

Cheers.

I have been considering applying a logarithmic scale, but I don't think it makes it that much more readable for most people. The solution is probably double Y-axis that appears in certain situations; if A is N above average value of A,B,C combined then create a separate axis for just data type A. Something like that. But I'm open for other suggestions.
