Does anyone know if it is possible to create a "half donut" style chart in Vision?
I can create a full donut by simply adding a circle to the middle of a pie chart.
For a half donut, one method might be to append a "50%" line to the dataset so that the real data is compressed to one side of the pie chart. I think that this would result in incorrect labels or mouse overs and would have some wasted screen real-estate.
Is this possible with jfreechart or another solution?
