Directly to your questions:
You can add point labels in pie chart by setting the pointLabelStyle textHidden
series.style.pointLabelStyle.textHidden = NO;
series.style.pointLabelStyle.textColor = [UIColor redColor];
After that you can customize the point label text by handling chart:labelForDataPoint:property:inSeries:atIndex:
method of TKChartDelegate
- (TKChartPointLabel *)chart:(TKChart *)chart labelForDataPoint:(id<TKChartData>)dataPoint property:(NSString *)propertyName inSeries:(TKChartSeries *)series atIndex:(NSUInteger)dataIndex
TKChartPointLabel *label = [[TKChartPointLabel alloc] initWithPoint:dataPoint series:series text:@
"my label text"
Finally set the labelDisplayMode
property to TKChartPieSeriesLabelDisplayModeOutside
to place point labels outside of the chart:
series.labelDisplayMode = TKChartPieSeriesLabelDisplayModeOutside;
does not support point labels with lines and this should be implemented with code. This feature seems reasonable and I logged it in our feedback portal. Use this link
to track its status.
does not support 3d effects. I logged this too in our feedback portal. Here is the link
I hope this helps. I updated your Telerik points accordingly.
