Plotting graphs on Mini2440

Abhishek Ekhare
I have tested my Mini2440 to write some text on the 3.5" display.
I have used the framebuffer to do so.
However, i want to plot some graph on the display.
I came across this video on youtube:-

Can i do write a code to do the same plotting as shown in the video using
framebuffer ??

I mean, without using Qt.
