Hello!  
I use Grafana as visualisation tool for all metrics of my Prometheus datasource.  
I have a question concerning time ranges. I get Cloudflare bandwith (cached+uncached bandwidth) metrics. When I want to display graph and **Total value** of this metric _cloudflare\_pop\_bandwidth\_bytes_ in prometheus the value it gives for _sum(sum\_over\_time(cloudflare\_pop\_bandwidth\_bytes[24h]))_ is right just like for 1h, 24h and 30d, but in Grafana dashboard the indicators are different for the same time range.  
For example, when I select **last 30 days** on Time Range panel in Grafana it returns this value **219.30 TB** which is less than it is for 12h or **24h (223.05 TB)**, which is not possible. Also, when I compare **Total value** in Prometheus and Grafana, the values are different.  
**This is my query and value per Petabytes in Prometheus for 30 days:**

**And this is the graph for same metric in Grafana for last 30 days:**

Thanks in advance.  
Looking forward to your answer.

You need to use the function sum over time with a range vector same as step [$\_\_range]
