I'm playing around with the .NET api for the rest webservices. I've looked up an iteration, and now I would like some data to build a burndown chart. I can find all tasks, and see estimates and todo, for a current image, but how do I find previous "snapshots"? Like, yesterday's ToDo.
The reason for doing this, is that the only way I've been able to "download" burndown charts as images, have been limited to a very small resolution and I need to present them on a big infoboard.
