Better Living Through Charts and Graphs

Back in March 2013, I decided I'd lose some unwanted 10 pounds I had gained and go back to what I considered my ideal weight and waist size so that I can fit into my favorite pants and shirts I simply refused to give away or replace. I managed to reach my goals in 6 months, with the help of a couple of smartphone apps that allowed me to monitor my caloric intake and expenditure through diet and exercise, respectively. But just as important, if not more, was simply measuring on an almost daily basis my weight and waist size. It gave me a solid and immediate readout to how well I was eating and working out. Ultimately, it was trying on those clothes and not feeling them too tight to button that showed it had all worked.

But suddenly, things started fitting tight again. What happened?

I looked back at the chart of the numbers I had been tracking all these months and saw that I had suddenly gained both weight and inches. But why then all of a sudden? The graph of my data gave me some clues.

As I've indicated by the two icons, my sudden gain in pounds and inches coincided with two things: the autumnal equinox (September 23), after which the days get progressively shorter, and Halloween (October 31), around which candies become excessively and too easily available.

Every year, around this time of year, my body and my spirits slow down. I start to eat more and move less. I feel less motivated to do anything and I sleep more. So this, coupled with very easy access to large amounts of sugary candy, probably combine to explain my sudden gains.

Knowing this now motivates me to crank up my exercise routine, something I should have done earlier in the fall in anticipation for my annual slow down. And also keeps me from munching on the leftover Halloween candy in my office.

Many people track fitness and other progress by taking pictures, which is great. But there's nothing like a graph, a picture of the actual numbers that measure what matters, to tell you what's going on, and how you're progressing, as well as offer you a handle on unexpected changes in course.

No video. Just the song, and a graph.

From the album "The Sophtware Slump" (2000)

"birds come...and then they go"
yeah
i traded laughs
in for charts & graphs
but all that's only fun
until evening comes
your guess as good as mine
as to just what kind
of trouble i might find
tonight out of my
my mind

The "official" Fun vs. Effort Graph of Pets

I like this graph. It uses the actual subjects of the graph as representations of the values reported. Edward Tufte would be so proud!

Which is why it's a shame they violated what to me is a fundamental rule of graphs. Ah well. Good effort College Humor. This other "official" version corrected some of the mistakes of the above version (though they did away with the cool size proportionality of the first graph).

What caused the meth epidemic? The answer was hidden in a graph.

Source: Derrick Quenzer, Steve Suo/The Oregonian. Y-axis indicates magnitude of increase, 1 = starting value, 2  = doubling, 3 = tripling.

Reporter Steve Suo of The Oregonian was investigating the dramatic worsening of the meth epidemic, asking, what caused the dramatic rise of methamphetamine abuse in the western United States?

The answer came from the graph above. Suo gathered extensive amounts of data from numerous sources and compiled what he found. He noted a rise and decline of various meth abuse indicators over time. One surprising aspect of the pattern is that it occurred in different states across the western US, and the patterns seemed synchronized. Further investigation revealed the rises were positively correlated with the purity of meth on the streets, and the decline of purity was negatively impacted with increased regulation of the raw materials of meth (see shaded boxes in graph).

Thus, the numbers clearly indicated that with proper regulatory intervention, the meth epidemic can be controlled. Too bad these regulations get in the way of fat profits for companies that sell cold medication, or else we would have wiped out the meth epidemic ages ago.

For a fantastic piece of investigative journalism, watch Frontline and The Oregonian's story on "the unnecessary epidemic". The facts, the numbers, and the stories will shock you. One thing that struck me is how much the graphs, the math and the numbers speak to policy formulation, and how much they are ignored in the face of large profits for a few.
