Creating pie chart in general/grouping data


i am struggeling by creating a pie chart. I have a time series based set of data stored in a postgreSQL.
I have set up several panels like stats, graphs and histograms which all perfectly works.

But if i want to set up a pie chart on the same set of data, i am not able to set my group of data or the thresolds for.

my data are in a range of 0…max500, so i would like to group them by 0…100, 100…200, 200…300 and greater 300…

Maybe i missed a general setting for so a small hint would be great


welcome to the :grafana: forum, @patwekan

can you share some of the data that you are trying to visualize using the pie-chart?
