The graph, for all those who are curious, was a temperature profile from an experiment that I and a bunch of engineers did together in our university days to study heat transfer on some rods of different compositions.

The graph turned out to be not quite useful, since this was the graph before accounting for error, so it had to be redone. Not quite freedom, after all! However, I couldn’t resist using it as a comic.

The program was MATLAB, also.
