For firearms they're a bit cryptic:
#stats_plot1 = aimspeed
#stats_plot2 = accuracy
#stats_plot3 = crit

But there's also:
#stats_bar_reloadspeed
#stats_bar_maneuvrability

Thanks, I figured it would be the name, but is there a way to actually modify the values referenced e.g. have a damage graph in addition to crit chance? Or perhaps modify the accuracy graph with a higher maximum accuracy value?

No, there's no way to reference a different parameter.

The values are plotted in relation to the min/max values of that specific param (eg accuracy) across all weapons.

That's a shame. There's so much hidden information, and min/max plots need to account for all potential bonuses, not just the weapon itself. Marksmen rifles for example don't appear to get any benefit to accuracy from scopes.

Could I get around that issue by creating a blank weapon that isn't assigned to any units?
