Atom Matrix 5x5 Graph

Hi Folks,
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.
