Not clear if/when data statistics such as minimum and maximum are calculated #342

Open ICHydro opened 1 week ago

ICHydro commented 1 week ago

Describe the bug it is not clear if or when statistics such as daily minimum and maximum are calculated. After importing new data, these statistics show up as zero in the "validation" page (see screenshot).

Expected behavior Either they should be calculated automatically during an import, or there should be a way for the user to request their calculation manually (perhaps together with the calculation of daily and monthly aggregates - see also issue 339)

These are not statistics, but input data that is pulled from the input file, if available. If there's no columns for the maximum and minimum, then this data is set as zero.

OK, thanks. I can't see a reason why one would want to import minima and maxima of individual data points. Most data points are a single observation anyway, and therefore do not have a min and a max. Some sensors may provide a minimum or maximum over a time interval (e.g, minimum temperature) but this can be treated as a separate time series. I will check with FONAG why this functionality is present in their system.
