My initial thought is to experiment with a Custom App called Super Customizable CFD. You can find the App in the Rally Community GitHub account here
The settings in this App allow you to choose the Portfolio Item (Feature) and then Group By: Portfolio Item State. If you could test/experiment with this and then provide feedback if there are any gaps or it provides the data visualization you are expecting. It is a Custom App so you have to use the Custom HTML App to add. Let us know if you need help with that too.
The main things to configure in Settings are:
- Artifact Type: E.g. Feature
- Group By: pick the attribute of the artifact type that will be used for generating the summary data for the chart. E.g. State
- Measure: pick the attribute for how the data summary should be calculated. E.g. Count or Plan Estimate etc. there are a few options there too.
