What Grafana version and what operating system are you using?
- v11.6.1 (ae23ead4d9)
- 20.04.1-Ubuntu

What are you trying to achieve?
Truly understand the meaning of ‘Total’ and other values shown in a Legend. -
How are you trying to achieve it?
By perusing the web, esp. this article. Relevant extract:
Let us now focus on the first two points. Remember, each dot represents the increment in requests in the time between the dot and 1 minute behind it. If we have 20 points in 5 minutes, between two points, we have an interval of ~5*60/(20-1)= ~16sec. Now consider the following scheme:
P1 P2
|---------60s--------|--16s--|
|--16s--|---------60s--------|
Is Total really overcounting, as implied by the P1 and P2 overlap above?
- What happened?
I don’t know enough about Grafana to trust the linked article with certainty, although related web results do seem to support it. For example:
Total in legend value is always a sum of the points returned from InfluxDB.
My datasource is Prometheus, though I suspect the same holds true for it.
The opening of the article’s last section probably summarizes its position:
Well, maybe the best option is not to use any summarizer in the series legend.
Is the article’s position valid, there really is no legitimate use case for “any summarizer in the series legend”?
