Bar chart of mirrored column

Hi all,

i would like to create a bar-chart in my dashboard that shows the sum of all values in a column within one group.
The column that I like to visualize is a sum of a sub-item colum. This sub-item column sums values collected from a linked column.

My bar charts visulalize “0” values even though in split-mode the right rows are selected and the correct data is in place.

Anyone know how to solve this error ?:slight_smile:

Br,
MJ
