Plot for Will MATLAB Answers converge?

This plot is disabled.

Included from trend description:

Here I present two simple ratios:

  • answered questions over total number of questions (ANTO)
  • accepted answers over answered questions (ACAN)

A very crude measure of quality of the forum could be the convergence of the two ratios to 1.

The ratios are correlated by construction but it's interesting to observe the delays in the adjustments and to monitor deviations from the optimal path.

Could we see:

(Answered + (doit4me tags && not answered)) / total?

I am trying to figure out how to query correctly and which "questions" to ask.
