Add date to charts in web UI

Description

The charts produced by the UI are great for an overview of what happened when, but when doing load and stability tests that run for days, it is very difficult to see which day what happened. Adding the date to the X axis in addition to the time and/or the mouseover information would make the charts a lot easier to read in these circumstances

I think that sounds like a useful option, maybe even something that could be automatically enabled once the test runs for more than 24. But someone needs to build it :)

I would also say that it could be quite useful being able to zoom in on the charts, also for having a better visibility in the tests that run for days.
