Project: graphing with graphical LCD using microcontroller

anyone knows what LCd best suits my project?.. the project goes like this: An LCD will dipslay a graph of temperature profile of a heater -- that is, a thermocouple connected to the heater sends signals to the microcontroller and the microcontroller must send signals to the LCD to graph the temperature versus time line graph.

If anyone knows, how should the program go?..please help me


Control it with a picaxe.
