Hi @oswardlx ,

You can modify this panel's relative time in query options.

thanks! But there is another issue, when I increase the time range, the number of interface calls decreases

Hi @oswardlx , sorry for the late reply.

There is another option Max data points when querying series with Range type. Prometheus will merge data points for better performance, and the latest value shown on the panel will be processed as well. You can modify the Max data points and run the query again, and you will find the value is changed. To get the actual latest value, you can query with the Instant type.

Hi @oswardlx,

After some research, I found a better way to display the latest value and sparkline simultaneously in the Stat panel. Need to query with Both type and use some transforms as follows. The updated dashboard is in the latest commit.

Check more details on the reply I wrote on Grafana Forum.
