I posted a new item on the JMP blog about visualizing my nearly four years of sleep data collected with a BodyMedia FIT armband.
My data reflects the sleep disturbances brought by a newborn and also shows seasonal variation in my sleep patterns. It was really only by stepping back and looking at the whole data set that I was able to see the seasonal patterns. That kind of info is really hard to see when all you have is summary reports at the week or month level like the ones BodyMedia provides.
You can see the whole blog series so far here.
