Sprint burndown chart does not reflect the correct data
Hi,
We are using RTC 2.0.0.1. We often find that the sprint burndown chart does not reflect the correct hours as shown in the sprint plan. For example, we are currently half-way through a sprint, and the progress bar of the sprint plan shows 432 hours done out of 828 total hours. However the sprint burndown chart plots the highest point as 511 hours only. Why is there a difference? Also, what happens if tasks estimated for a certain number of hours are added by different team members on a certain day, but the tasks with an equivalent number of hours are also closed on the same day? As the data snapshot is taken only once every 24 hours, it will not reflect any change on the burndown chart. How can we have the data snapshot taken more frequently? Regards, Abigail |

The last point in the burndown chart is live and will show you up to the second up to date data.
The other points are taken in 24 hour intervals. So yes you could miss peeks that happen during the day. We highly discourage increasing the frequency of the snapshots. In a system with numerous work items, doing so, will for sure impact the performance of your server and will increase the size of your DB significantly. As for the differences between the Burndown chart and the sprint plan, which do you think is displaying the correct value? |

The progress bar in the sprint plan displays the correct value (I totaled the hours in the tasks - both estimates and time spent). The difference between the sprint plan and the burndown chart is over 300 hours which is way too much to be only due to the data snapshot taken the previous midnight. |
