What is the "Ideal Trend" line in TFS Sprint burndown chart based out of? Original Estimate or Remaining Work?
If I add more tasks mid sprint, my remaining work line will show a bump. Will the starting point of "Ideal trend" line also move up in this case?
You can find some explanation here: Sprint Burndown (Scrum).
The Ideal Trend line indicates an ideal situation in which the team
burns down all of the effort that remains at a constant rate by the
end of the sprint.
It is based on Remaining Work and represent how you have to update your Remaining Work in your sprint to get 0 hours of work at the end of a sprint. If you add new tasks after sprint start you will have non ideal line that adopted to new number of hours of tasks and duration of a sprint.

I have a TFS query that pulls in data from recent sprints, in order to display a chart on our dashboard. However, as documented:
When a chart contains more than seven items within the data series, values in the eight-plus items are consolidated into a set labeled "other"
This is exactly what happens with us. The first few Iterations on the chart are static, and as every Iteration passes by, the "Other" row increases.
How can I alter my query to only pull in the last seven iterations? I can't do something like Iteration ID >= #Current Iteration - 6 because #Current Iteration is supported only for Iteration Path, not Iteration ID.
There isn't any way to achieve this through in TFS for now.
However for VSTS, it's added now.
The deployment of this feature to all VSTS accounts is now complete.
You can find full details in our Release Notes
(https://learn.microsoft.com/en-us/vsts/release-notes/2018/mar-05-vsts#query-work-across-the-iteration-schedule-with---currentiteration).
TFS customers can look forward to the feature in a future feature
update.

Query work across the iteration schedule with +/- #CurrentIteration
The #CurrentIteration macro that helps your team track work based on your iteration schedule now supports integer offset. Easily keep tabs on the work that didn’t get closed with #CurrentIteration - 1, or look ahead at the work planned for future iterations with #CurrentIteration + 1. See the #CurrentIteration post on the Microsoft DevOps Blog for more information.
Update:
Logical expression: Work Item Type = any And State= any AND (Iteration= CurrentIteration OR Iteration= CurrentIteration-1 OR...)
I have just created a SCRUM project inside TFS, created a new sprint and assigned the proper tasks to it.The problem that I have is with the burndown charts' Remaining Work.
I mention that the sprint started today 31/10/2016 and it will finish sunday, 6/11/2016.
This is the picture that shows it.
Can someone please explain why the chart starts from 60 as remaining hours instead of 80? The sprint just started 40 min ago.
Both 60 and 80 is not on behalf of hours which means team's total capacity at the start of the sprint.
(1) Team's total capacity at the start of the sprint
(2) 0 Remaining Work at the end of the sprint.
Update
This is a normal phenomenon. For the remaining work, it will reduce the first working day's capacity.
If your today(10/31) did nothing, the actual graph, the blue area should start from 80 not 60. If your today(10/31) did 30 capticy,the blue area should start from 50.
For a test you can set start date from 11/5~ 11/13 which have 9 days and 5 working days. However the chart should still start from 11/7, the first working day.
Recently came across "Remaining Work" option in TFS, got no clue what it stands for, is it the time in hours that i am supposed to define against a task.
Remaining work is the number of hours you have left to complete a task. If something is a 4 hr task and at the end of a day you have managed to complete 1hrs work, you would update it to 3hrs remaining. You can update the remaining work as often as you like. You could just 0 it when there is no more work, or every time there is 1hr's less work remaining - or somewhere in between.
From this value, TFS can create a burndown graph of remaining work in an iteration.
There are fields for Original Estimate and Actual Work you can use if you need to track estimates and how long things took.
Remaining Work field can actually show if the original estimate has changed since you started working on a task.
I've got some problems with my TFS Burndown Chart. I've just created an Iteration (Sprint) with no start - end date. Then added some Working Items - Tasks each with their corresponding start - end date (lets say 10/06/2014). 6 days have passed since I realized that my whole Iteration (Sprint) did not have start - ending dates (10/06/2014 - 27/06/2014), so I've added those, but now... my Burndown chart is showing the progress only from dates 16/06/2014 to the current date, up to the finish date: 27/06/2014
Most of My Working Items (tasks) inside the Iteration - Sprint have their Start, In Progress and Finished within the current dates: 10/06/2014 - 16/06/2014.
Please Advice.
Not sure how your tasks have starting/ending dates. I thought all the default templates had Work Remaining on Tasks. Anyways, the burndown operates off the Work Remaining fields of the Tasks, you need to update that appropriately.
You should set start and end dates for the sprints themselves. Without start/end dates for the sprint itself, it can't project how much time you have left given the total task work at the beginning of the sprint. An iteration path (i.e. sprint) is inherently a period of time for doing your work (i.e. 2-4 weeks).
The Sprint Burndown Chart says I have about 150 hours outstanding.
The Sprint Cumulative Flow Chart suggests that I have about:
100 hrs 'Not Done'
150 hrs 'In Progress'
50 hrs 'Ready For Test'
If I sum up the actual SBIs in the sprint I get the following numbers...
100 hrs 'Not Done'
50 hrs 'In Progress'
5 hrs 'Ready For Test'
Can anyone suggest what's gone wrong?

Almost every time my TFS reports are off in a way where the math doesn't seem to work anymore, I've almost always done one of the following:
Made changes in the path hierarchy
Made changes to the iteration hierarchy
Marked items with a new state by editing process templates
Often it just requires repairing the queries the report server is using.
I recommend running an #project query and see if your current iteration + stuff outside your iteration add up to the numbers you are seeing.
