So i am getting 4 groups in stacked bar chart. Now Incase if one more severity gets added i may have to come back to the expression and add another. I would like to load theses stacked groups dynamically.
Thanks Pradeep and balkumar. That really works. Now I am trying to show a line in the same chart to show the total no of tickets. But if i add one more expression am getting the total for all severity.
