Wow, I really like that Fever Chart. I have never seen anything quite like it. I can tell you that there is nothing like this available by default in Microsoft Project, nor am I aware of any add-on software that would generate a chart like this for you. It appears in your screenshot that the Fever Chart was created in Microsoft Excel. If it were me, and I were required to create Fever Charts on a regular basis, I would probably export my project data to Excel and create the chart in that tools. But perhaps someone else has an idea for you. Hope this helps.
