You should implement TKChartDelegate
and override its UpdateLegendItem
method in this scenario. It will be called every time when a legend item needs to be updated. Consider the following sample:
UpdateLegendItem (TKChart chart, TKChartLegendItem item, TKChartSeries series, nuint index)
item.Label.TextColor = UIColor.Red;
Set the chart delegate before adding the chart to the superview and before setting the Hidden
property of chart legend to false
