Make x-axis linear in perf-dashborad graphs

Project Member Reported by majidvp@chromium.org, Dec 9 2016 
The x-axis in the graph is not linear which can be misleading. 

For example see: https://chromeperf.appspot.com/group_report?bug_id=540824

Because the x-axis is not linear it is very difficult to notice that the range in which the regression occurred is very large. This large range would have raised a red flag when deciding to investigate the issue but it was missed leading to many failed bisects.

Ethan, Jessi, is this already tracked in catapult?

We do plan to make the x-axis linear to chromium commit positions (which would make it hard to see when a large v8 roll is going in, for example, but probably be more intuitive to most chromium developers)

Comment 2 by majidvp@chromium.org, Dec 12 2016 

Linear to chromium commit positions sgtm.

Comment 3 by jessimb@chromium.org, Dec 12 2016 

It is not specifically tracked yet; there are comments here and there about the need (https://github.com/catapult-project/catapult/issues/2940). Should I create a catapult bug for it?

Comment 4 by sullivan@chromium.org, Dec 12 2016 

Yes, please, and archive this one with a link to the catapult one.
