Time Series: Legend and Tooltip

[dirkallaert]

What would you like to be added:
In the old graph panel, both legend and tooltip could be sorted by value (and null series could be hidden).

Why is this needed:
This is a very useful feature when a time series panel is displaying multiple metrics and you want to quickly see the values of the top metrics.

Sorting legend or tooltip by value is no longer possible with time series. This issue was already raised in several issues. In #30907 it was mentioned "indeed the time series panel does not have legend sorting implemented. Added it to the backlog for time series/graph work: #30564". But both #30907 and #30564 have been closed without this very useful feature being implemented.

Sorting by value in the tooldtip allowed our ops team to quickly spot outliers whenever an alert came in, after having switched from Graph (old) -> Timeseries and missing this functionality, it is harder to make sense in such situations. For example:

compared to previously:

Hi @kvz we added support for that in the new time series panel in 8.4.0 #43615

I was looking at issues related to the tooltip and I found this one. Is it on purpose that the default mode is Single compared to the old Graph where it was All? I would really like if I can make the All default (at least for myself)

[zoltanbedi]

You can't make All default. Is it on purpose? I don't think so. @dprokop wdyt?

@zoltanbedi I think @nikobearrr is referrring to this: https://github.com/grafana/grafana/blob/main/packages/grafana-ui/src/options/builder/tooltip.tsx#L31

changing that to multi changes the timeseries panel's default tooltip mode to All instead of Single

I upgraded to 8.4 (it says Grafana v8.4.2 (NA) in the help menu) but I don't have the option to sort the tooltip as shown in #43615 for timeseries graphs 🤔

anything else that could be missing?

[zoltanbedi]

I'm not sure, it should show. I can see it working on https://play.grafana.org

This was a deployment issue on our end, sorry for the noise! Works as expected now, thank you
