I would love to be able to create a box-and-whiskers plot, which shows the min, 25th percentile, median, 75th percentile, and max. Bonus points if I can visualize individual outliers. I see this as a variation on the scatter chart when one has a step-wise function (such as date or story points).
In particular, I would like to show the number of workdays in progress based on the assigned story point estimate. Right now, I can get a sense of it, but I’d love to be able to see this more precisely.
