Had a bit of brainwave last night... A couple of days ago I hacked together a basic graph to post up here showing heart rate zones. I also recently posted up a graph that my Polar gear kicks out showing various statistics. I suddently realised that there was nothing really stopping me from taking the raw Polar data and shoe-horning it into Google Graphs to come up with a dynamic online graph!
I've spent the morning studying the Polar file formats, and hacking out the bits I need, and it now looks like I have a prototype script up and running. At the moment there are a couple of assumptions regarding data ranges, however its not the hardest thing in the world to put in some proper validation. Once thats done I'll have a script that can accept any file from my Heart rate Monitor, and output a nice and pretty graph onto a webpage.
