From InfluxDB datasource help:

Group by time
Group by time is important, otherwise the query could return many thousands of datapoints that will slow down Grafana

• Leave the group by time field empty for each query and it will be calculated based on time range and pixel width of the graph
• If you use fill(0) or fill(null) set a low limit for the auto group by time interval
• The low limit can only be set in the group by time option below your queries
• You set a low limit by adding a greater sign before the interval
• Example: >60s if you write metrics to InfluxDB every 60 seconds
