Hello, I would like to ask for help for the first time. I have this stacked area chart with lots of categories. All are grey except for the one I choose (Category Select is a Parameter and is linked with Cat Select which defines the different color - blue). So the "highlighting" through the Parameter works. The problem is, that each time I select a different category, the order in the chart changes :-( I want to keep it still the same. Please compare selection of category 1 and 2. I tried to play with the sort of both the Cat Select and visit type, but it didn't help. Any ideas please?
Category 1 is selected:
When category 2 is selected, the order of the stacked areas changes (but I don't want it to):
