Wondering if anyone has a sample to draw a graph on the Atom matrix 5x5 LED ?

I have in mind to draw a line across the screen tracking temperature.
If I have a 25c range then I can round my values to fit into 1 row per 5 degrees.
I can then render the last 5 values horizontally across the screen.

I am optimistic someone has a library to do all the maths for this and I can just feed it 5 values ?

If not, I might have to come up with my own.
