Dynamic Graph of Random Walk

This figure shows a 24-hour random data sequence that is not correlated with known major events in the world. It is an example of a random walk, which may be likened to a "drunkard's walk". The steps are unpredictable in length and direction, so the trace wanders up and down around the mean value, but there is no trend. A blue probability envelope shows threshold for "significant" deviation.

The timing is set to show the 24-hour period in 15 or 20 seconds. But the display will be constrained by the speed of your processor. Use your browser's back and forward buttons to replay.
