InfluxDB, extracting Info

I’ve had a Aeotec Home Energy Meter in the house now for about 2 months and have OH2 and Influx/grafana charting the usage.

But is there anyway to extract this usage out or how to go about querying the results to get your energy usage for a date range? ie, a week, month, etc? I would like to now begin analyzing this data, when usage is it at it peak levels, etc, and then comparing to my actual utility bills.
