Yes,I already tried that forum post .In that i am facing problem like each series span as 360 degree.
My requirement is if as a user i achieved 50 percent of my task ,then donut series should span upto 180 degree i.e. only half donut should be visible.
So what i did is[where d1 is my object of SChartDonutSeries]:
d1.style.flavourColors = [NSMutableArrayarrayWithObjects:[UIColorredColor], [UIColorclearColor], nil];
d1.style.showFlavour = YES;
d1.selectedStyle.showFlavour = YES;
I set other 50 percent as clear color,but if i click on this portion of series,color again appeared...
Eagerly waiting for ur reply..
