I recently posted a question over on Stackoverflow and wasn't able to get a response from the community.
Is there a bug with the AjaxControlToolkit's PieChart, or am I forgetting something? Using the sample pie chart provided with the library's sample site, I removed all but two PieChartValue's and set the data to 70 and 30.
However, having only two values is not rendering the chart properly. I've verified it in both IE9 and FF11. If I add a third value and adjust the data to total 100, I'm golden...to a degree. If I have a data value over 50%, the PieChart doesn't render properly. A single value of 100 renders incorrectly as well, displaying a vertical line.
It looks like when the chart renders, it does so using the same arc by the shortest distance from point to point.
I thought the PieChart was supposed to support 1 or more data elements according to the library.
