[question]: Filter empty flows?

[bbuchalter]

I am generating the data for my flows dynamically. Adding guards to ensure that each flow does not have a zero value would be a burden and feels like a reasonable option to support. Does this support exist?

It is better to preprocess the data, because chart might need to do the filtering on each update. I did not take a look though, and its always possible to cache things - at the cost of complexity.
