Hello,
I am looking for a way to compare data from influxDB, for example I need to compare the number of persons that are stored in July 8 between 7:00 a.m and 10:00 a.m with the number of persons of July 3 between 9:00 a.m and 11:00 a.m. This dates and hours must be selected by the user in the Dashboard, preferably with a date time picker or something similar. And all the data present in this time range will be added together.
The temporary solution that I have implemented, is to create multiple variables to select these dates.
The user can select the variables:
With these variables I use bar charts to graph the sum of this query in the next way.
This solution works, but I would to ask if there is a more efficient way. For example, if there is a way to use two date-time pickers instead of using multiple variables.
Thanks for your help!
