pie chart colours

How do I change the colours of the pie chart?

Hi David,

Thank you for contacting us.

To change the colors of the pie slices, you should use TKChartDelegate's chart:paletteItemForSeries:atIndex: method to return a palette item that suits your needs. The following code snippet will change the color of the slice at index 3 to yellow:

- (TKChartPaletteItem *)chart:(TKChart *)chart paletteItemForSeries:(TKChartSeries *)series atIndex:(NSUInteger)index
{
    if (index == 3) {
        TKChartPaletteItem *item = [[TKChartPaletteItem alloc] initWithFill:[TKSolidFill solidFillWithColor:[UIColor yellowColor]]];
        return item;
    }


    return nil;
}

Do not forget to set TKChart's delegate:

_chart.delegate = self;

More info about custom drawing in TKChart you can find in out documentation.

I hope this helps. I will be glad to assist you if you need any help.

Regards,
Adrian
