I am trying to use TeeChart to display a Pie which has to show me the percentages also.
The problem is that if you sum up all the percentages it isn't 100%. It's really frustrating.
I have set the Series.Marks.Style to "Percent Total" and the total is actually bigger then it should be. After I calculated a bit to see why the sum differs from the real sum of values, I realised the 1st value is added twice. This is why the percentages are wrong.
Why does it do that?
