As you can see on the left of the graph, tilted 90 degrees, the Yellow means the Acceleration of the car. The blue line represents the power and the tyres red.
Yellow is the acceleration line and shows the car it's current acceleration curve.
The blue line indicated that there is too much power, thus the wheels are spinning. It would require a different gearratio, giving first gear less acceleration, or bigger tyres to get that acceleration down on the road. The red line indicates that the tyres are big enough to get to that acceleration number, so there is space for more power in those gears. So when the red line is higher, the car could accelerate more, before the tyres start to spin.
Yours looks like about the same as mine, lots of wheelspin in 1st gear, decent tyre coverage and space for more acceleration in the other gears.
