5 years ago @ChristophRuckstetter it's difficult for the library to determine that accurately because of different character sizes, etc. The consumer of the lib is in a better position to determine that, you can sweep through your data and find the longest label like you described and then call leftMargin(<px>) and rightMargin(<px>) accordingly. You can even do it dynamically if your data changes.
we don't know how much space our groups and labels need. So it's pretty hard for us to set the margins manually to a fixed value. It would be great if it would be possible to automatically set the left and right margins depending on the longest group/label.
