Life in Motion

So, this is a graph showing an example of me walking and then jogging on the treadmill using my device (negative is correct, as forward motion becomes a negative value apparently). Previous graphs were even more radical like the one on the right here, but putting it up, higher from the surface seems to solve that pretty well. I will see if I can improve this further, otherwise I will solve it in code by applying some kind of filter. Note that this is raw data from the sensor, so I guess some kind of filtering needs to be applied anyway... But this is really looking good I must say! Note also that the positive peaks are really few, compared to all the samples made.
