Description Andrew Pickering 2021-08-26 09:26:58 UTC

The graph tooltip shows the data for a single timestamp. There can be hundreds of data points for the timestamp, but the tooltip is limited to showing the top 20. In this case, the code is quite inefficient because it both sorts and then processes all data points before throwing away all but the top 20.

checked with 4.9.0-0.nightly-2021-08-29-010334, the tooltip shows the top 20 results, and the it takes less time to get the result
