To put it simply

on the bottom you have a Torque scale and to the left you have a amps scale

At 15 volts, the test data is as follows

as more power is applied, more amps are being pulled (hence the possitive slope for the amps line)

same goes with efficiency... for a 1515 at 15 volts... peak efficiency is at max amps pulled... (really good for speed runs / high speed tracks)
