Monthly bar chart problem

Hi everyone,
I am trying to show monthly energy consumption in a xy chart (column / bar chart). I’m using a tag history binding with periodic query mode and range aggregation.

Unfortunatly I’m not able to get the an acceptable result. When range is set to Month, there is no value for February, and the last value is for des 26. I’ve been playing around with different ranges, but nothing seems to work.


I’ve set up time series for this year and last year in the xy chart. The colums stays on top of each other . How can I make them beside each other?
