What can I learn from an Open by Priority chart?

Dynamic planning is most effective when you know the relative priorities of work items you are tracking. The Open by Priority chart helps you check that your team is working on the optimal mix of artifacts.

Use the Open by Priority chart for a quick overview of the type of work your project is working with. A glance at this chart can suggest some broad generalizations, which you'll then want to test by examining your planning folder contents more closely.

Note: The Open by Priority chart won't tell you how much work is involved in the artifacts that it measures. For that, check the Burndown chart.
