How can I filter a histogram dashboard panel for traces?

[jansorg]

I'd like to create a histogram dashboard panel for durationNano for a certain trace event.
It seems that the query field next to Traces is defining what's used for the buckets. Now I don't know how to filter and define the value for the buckets at the same time.

I'd like to show durationNano in the histogram, but only for trace events with name = shellcheck.execute.

This doesn't work, it's always using 1 on the Y axis:

Thanks!

What were you expecting it to show? You are summing the durationNano for an interval. The result of the aggregation is one SUM(durationNano) for each interval. This result then gets plotted as histogram.
