I am using ASP.NET and C#. All of the pie chart controls that I see will only allow each category to be assigned one value.
For example, I could make a list of email campaigns and associate each campaign with a number of messages sent.
But what I want to do is show a pie chart which displays multiple values per campaign. For example, each campaign would show the number of messages sent, number failed, and number pending.
Is there any solution for this kind of pie chart in ASP.NET?
