I have a donut chart summing duration of machine states. Currently it displays it by interval, but I’d really like to see the breakdown by percentage. I’ve tried going through all the options and even in using expressions but as it sums each Duration independently I don’t see a way to “sum the sums” so I have the total interval to divide by.
Am I missing something?

There’s not a way to see the percentage, and the expression editor doesn’t support that sum of sums concept you’re talking about to create the total interval.
