[edit] Summary

This image was created by me. The data shown is random numbers generated by a program I wrote. The image itself is a screenshot from my charting program, captured with xwd and imagemagick.

The green middle line is a 10-day simple moving average, the blue outer bands are drawn at 2 standard deviations away from the average.
