For today's visualization I plotted my Nike Fuelpoints (Nike's somewhat arbitrary point system for tracking activity) against the average daily temperature here in the south of France. The point is to observe whether heat changes my level of activity and exercise. I chose to "fill" the line chart in to illustrate the average progression over time despite the peaks and valleys.
Before you think I'm some sort of lazy sod I'd like to impart that the Nike Fuelband doesn't measure all activities equally and isn't able to track the hours of swimming I've done in the ocean with my kids every day because it isn't waterproof. That said, the fuelband is great because it provides feedback on your daily goal without being synced with a quick visual colour bar.
