label: pv_total{app="example",day="2023_03_15",} 123.0
Current Grafana dashboard：image
The day in my data is redundant, I want to display without it in the data
i hope my dashboard is this(last 7 days, just one line):
i don't know how to write query metrics expression to delete the day filed of value
i hava try expression label_replace(), but it's not work,
You can use prometheus' sum() method, in your case, like this: sum(pv_total{job="$job"}).
