@bmarkons Minor bug here:

When one of the benchmarks do not have enough results, it isn’t display on the X-axis correctly.

Hmm, it’s because both series use common x-axis categories. I had some time thinking about what would be the best way to display comparisons. Probably would be the best to have it without common x-axis categories with results ordered by their commit created\_at timestamp. I have [Highstock](https://www.highcharts.com/stock/demo) in mind since it has very nice features for displaying multi series graphs.
