controlling and graphing a variable.

*disclaimer this code is a snippet and is not in any function and is missing some of the basic things.*
int Map = 10;                                               //map variable = varmax/5.
float ledvl = 0;                                            //decimal for the leds var/Map.
int led = 0;                                                //the pwm state of the pin.
int ledp = 0;                                               //the percent of pwm to the led.

    *this code following is in my every second things.
    if (Button == 6){                                         //toggles controll for v1.

      }

      }
