incorrect chart in case leading data is missing from one series

In case there are 2 series in the chart and they are not in sync, both series start at the beginning of the chart. In case one of the series is missing leading data, the chart is incorrect.

LNG real time and the regular LNG Kernel builds have different build numbers for the same day making comparison impossible.

Mike, this is a whole different problem and should be addressed in another bug/feature request.
Anyway I'm not sure we can do much with that particular problem, maybe allow the architect of the chart to ignore build number attribute and show dates instead if he choses to.

[Tyler Baker (tyler-baker)]

The issue is that there is no way to get a mapping between two arbitrary build numbers.

Example:

Build1: 1,2,34
Build2: 1,2,3,4,5,6,7,8

The solution is to not use build.id in your filter, it will then use timestamps to synchronize the results.
