Jana Beck on Visualizing Her Diabetes Data

As you may know, we get excited when someone in our community uses interesting data visualizations to help tell their self-tracking story. Jana Beck is no exception. As a woman living with Type 1 diabetes she’s constantly learning how to better understand what her Dexcom data is telling her. In this talk, Jana follows up on her previous show&tell presentation with some new visualization techniques she’s using. If you’re interested in Jana’s methods be sure to check out her Github repository and her work with Tidepool.org.

(Editor’s Note: I very interested in Jana’s use of Chernoff faces for multivariate data visualization. If you’re using this type of visualization for your own data I would love to see it. Get in touch.)

QS Gallery: Mette Dyhrberg

This great QS visualization comes to us from Mette Dyhrberg, a member of our QS New York community.

I gained a lot of insights from this heat map. The most obvious weight gain was no surprise — that’s when I periodically don’t track. In any case, the big picture patterns are easily identified with a heat map.

Realized looking at this heat map that the point of no return was mid-April 2012 — my data shows that was when I switched protein shakes with an egg based breakfast. I have since experimented and seen that protein shake in the morning seems to keep my blood sugar more stable and as a result my weight under control!

Tools: D3 Calendar View visualization, Withings Wireless Scale.

We invite you to take part in this project as we share our favorite personal data visualizations.If you’ve learned something that you are willing to share from seeing your own data in a chart or a graph, please send it along
