I will be looking for it today and let you know 👍
from rkpiechart.
I had the same problem, you just need to add a condition in the RKPieChartView class in the function calculateAngles(), "if item.endAngle! > 2 * π && items.count! = 1" , I leave the complete code of the function.
private func calculateAngles() {
totalRatio = items.map({ $0.ratio }).reduce(0, { $0 + $1 })
for (index, item) in items.enumerated() {
item.startAngle = index == 0 ? 3 * π / 2 : items[index - 1].endAngle
if items.count == 1 {
totalRatio = 100
}
item.endAngle = item.startAngle! + (360 * item.ratio / totalRatio).degreesToRadians
if item.endAngle! > 2 * π && items.count != 1 {
item.endAngle = item.endAngle! - 2 * π
}
}
}
I hope help you

My way, not sure about this:
private func calculateAngles() {
totalRatio = items.map({ $0.ratio }).reduce(0, { $0 + $1 })
for (index, item) in items.enumerated() {
item.startAngle = index == 0 ? 3 * π / 2 : items[index - 1].endAngle
if items.count == 1 {
totalRatio = 100
}
var diff = (360 * item.ratio / totalRatio).degreesToRadians
let pi2 = π * 2
while diff > pi2 {
diff -= pi2
}
item.endAngle = item.startAngle! + diff
}
}

If you have only one item, and you want It's occupy whole graph (100%), like this:
private func calculateAngles() {
totalRatio = items.map({ $0.ratio }).reduce(0, { $0 + $1 })
for (index, item) in items.enumerated() {
item.startAngle = index == 0 ? 3 * π / 2 : items[index - 1].endAngle
if items.count == 1 {
items[0].ratio = 99.999999 // if ratio <= 100 then crashed. so just input 99.9999
totalRatio = 100
}
item.endAngle = item.startAngle! + (360 * item.ratio / totalRatio).degreesToRadians
if item.endAngle! > 2 * π {
item.endAngle = item.endAngle! - 2 * π
}
}
}
But this solution is just a fake. And this is very easy way.
