Is there an "In Progress" point on the burndown chart?

[Philip Coler]

I would like to see a point marking when a story is set to "In Progress" on the burn down chart. It would make it easier to see if a specific story was estimated correctly or took too long to complete. Is there a functionality like this already built in?

[Walter Buggenhout]

JIRA has a built in field called workratio which compares the original estimate vs time spent. You could create a filter saying:

Project = xxx And workratio > 100

This would give you all issues where time spent was more than the original issues. 100 stands for 100%, btw.
