Graph B - If we change the scaling and add some grid lines the graph gets even easier to read and the shape of the curve is much more telling. The torque peak is happening at the same place and the horsepower is falling off at the same rpm but now you get a much clearer picture of what is really happening. We did not change the data but we put the data in a much more usable form. By changing the scaling we eliminate the parts of the graph we do not need to see. There was no information below 300 hp or 300 foot-pounds of torque. So why not make the graph reflect that and tell a much clearer story.
