Velocity Chart in Rally [closed]

问题:

I am working on a project to pull out data from rally and create a velocity chart.

I understand the REST Web Service APIs to use are Defects, Iteration, Hierarchical requirement and Iteration cumulative flow data.

How are the calculations are done to calculate the velocity per iteration for a particular project?

What data is required and how can it be achieved? Right now I'm able to pull plan estimate of all accepted user stories and total plan estimate.

I wrote an app recently to calculate velocity. I used the story points of all accepted stories/defects in a time period (iteration/release). My numbers ended up matching what Rally had for my velocity, so I believe that is all it takes.
