I can create a time series visualization with two metrics and have one of them offset by a specific interval (which is pretty cool, by the way). But when I mouse over the chart to see the value of the offseted metric, it shows the non-offset time. It would be nice to show the offset time for the tooltip for that specific metric.
This sounds like a bug to me, or at least I can't think of a reason off-hand where the non-offset time would be desirable in this situation.
Yeah... this is a known bug. It's because when the data is created we re-adjust the offset back to the current time. That means the tooltip displays the re-adjusted time. This is going to require some re-factoring to allow the time stamp for the tooltip to be different then the timestamp of the actual data.

I've tested this issue for versions >6.5.4. Looks like now it works correctly. I see time with offset value in tooltip. See gif below:

I would close this for now. In case someone can still reproduce that on an up to date version, pleas feel free to leave a comment, then we'll reopen that issue.
Starting from 7.5, TSVB is using elastic-charts as chart renderer. The current tooltip shows the data related to every data points on the same x axis position.
TSVB is basically transposing each date of the offset dataset, but the x axis is always rendered with the same start and end date. To fix that we should render a custom tooltip header with a double timestamp on it or something similar. It's in a way connected also to this: https://github.com/elastic/kibana/issues/60013 other enhancement.
This is still a problem. I don't see a date on tsvb when you offset. I am using 7.8.0. there is no date shows up when you hover the mouse over and there is no X axis shows up

I am also facing this issue, any update on this? @epixa
