Point Color

[Ruben]

Is there a way to have a different colors for different point on a single line for TKChartLineSeries?

Hi Ruben,

We have a demo in the iOS Samples application that shows how to create custom point labels. I believe with the proper modifications it will fit your requirement. Please have a look at it, you can find it in your local Telerik UI for Xamarin installation. Simply navigate to the Examples/iOS folder and have a look at the Chart/PointLabels/CustomPointLabel implementation once you have opened the solution.

Thanks for the reply. However, my question is about points themselves, not point labels. I already figured out how to have different colors for points on a single series but now can't find a way to do the same for point shapes? Can I have points of different shapes on a single series?

Hello Ruben,

You can change the color of the points as well by overriding the PaletteItemForPoint(shown in the demo - CustomPointLabels.cs):

public override TKChartPaletteItem PaletteItemForPoint (TKChart chart, nuint index, TKChartSeries series)
            {
                if (series.Index == (nuint)this.selectedSeriesIndex && index == (nuint)this.selectedDataPointIndex) {
                    return new TKChartPaletteItem (new TKStroke (UIColor.Black, 2.0f), new TKSolidFill (UIColor.White));
                }

                if (series.Index == 0) {
                    return new TKChartPaletteItem (new TKSolidFill (new UIColor ((float)(108 / 255.0), (float)(181 / 255.0), (float)(250 / 255.0), (float)1.0)));
                }

                return new TKChartPaletteItem (new TKSolidFill(UIColor.Green));
            }

You can return different palette item according to your custom logic.

Unfortunately, it would not be possible to assign different shapes for the points of the same series.

Have a great weekend.
