I don't like these graphs as they specify too many paramateres and don't help basic jetting, but they are good however for advanced diagnosis.

LOW DOWN RESPONSE (IDLE TO 1/4 THROTTLE)
If you want better idle and/or low down (throttle position) response adjust the fuel/air screw. Only change the pilot jet if you are winding this screw below 1 turn or over 3 turns.

MID TO TOP END POWER (1/4 TO FULL THROTTLE)
If you want more mid range or top end (throttle position) response, then look at the main jet/needle clip circuit. Unless the plug colour is white or black after a good wide open throttle ride, leave the main jet alone. Adjust the clip on the needle (higher to lean the jetting out, lower to richen the jetting up).
