There are no interrelations between these two settings. For example, if rate(http_requests_total{job="api-server"}[5m]) is your PromQL query, it yields a single value when you execute it at a specific point in time. If you have a Grafana dashboard with a 2h time range, then Grafana just repeatedly executes this query at a series of point in times during the past 2 hours, and displays you the result of each query as e.g. a graph.
For example, if the time range of your Grafana dashboard is 2h and the interval is set to 1 minute, then Grafana executes your query 120 times during the time span ranging the past 2 hours. The results of all these queries form a graph and that's what you see in your Grafana dashboard.
The interval with which Grafana executes the query is determined by the Max data points and Min interval settings in the Query options of your Grafana dashboard:
See the explanations about these settings in the Grafana documentation.
Answer from weibeld on Stack OverflowNote: Grafana uses the
query_rangeendpoint of the Prometheus API to repeatedly execute the query over the given time range.

The quantile is calculated for each label combination in http_request_duration_seconds. To aggregate, use the sum() aggregator around the rate() function. Since the le label is required by histogram_quantile() to deal with classic histograms, it has to be included in the by clause.

rate() versus irate() in Prometheus (and Grafana)
November 5, 2018 - With a small query step and thus a high level of detail, you probably want to use irate() with a range interval that's large enough to cover three or four metric points. But for large query steps and only broad details, irate() will throw away huge amounts of information and you need to use rate() instead. This is where we come to Grafana.

August 10, 2024 - For example, using rate(http_requests_total[$__rate_interval]) ensures that the rate calculation adapts to the dashboard's current resolution, making it suitable for both high and low-resolution data. Note: Using $__interval in your Grafana queries is often sufficient for many types of queries, particularly when you want your data to automatically adjust to the dashboard's time range and resolution.
