Graphite's diffSeries Function

This function is incredibly helpful for comparing dataseries. You can add it to your render URL like so;

diffSeries(stats.timers.stat_thats_likely_to_be_higher, stats.timers.stat_thats_likely_to_be_lower)

Here's what that graph means.

  • If both series are equal, then it will produce a graph that hovers around 0.
  • If the second series is consistently lower, then the graph will be consistently > 0.
  • If the first series is consistently lower, then the graph will be consistently < 0.

Here's a more in-depth explanation and use case.
