Histogram Features

[timconradinc]

The ability to have multiple types of histogram on the same graph - so i could have min/max/avg on the same graph.

The ability to do basic math on histograms. As an example, I'm getting data in seconds. It'd be nice to have it in data/60 format at least.

The first feature, having multiple values on a single graph, will be made possible with #1536.

As for the second feature, that is currently the case with histogram-like charts.
