too much data too make graph

What is the way to go , to minimize the data measurements I get from The Dutch meters plugin

I’ve been trying to export to Excel, but can not find a function to minimize. number of readings. (a graph is not possible)
I also can’t find a value in the plugin to reduce the number of measurements.
Datamini says everytime timeout becource there is to much data.

And is it possible to see the day totals in datamine instead of a ascending value?


i also have the same plugin but i never get any timeout messages.
i have Datamine connected to a NAS, not sure if it makes a difference though…

a week, a month is OK, but a year always gives a timeout with this plugin
