ScatterSplineSeries

Overview

The ScatterSplineSeries are represented on the chart as data points connected with curved line segments. The ScatterSplineSeries inherit from theScatterPointSeries class and also require both axes of the chart to be of type NumericalAxis.

Features

  • Stroke (Color): changes the color used to draw lines.
  • StrokeThickness (double): changes the width of the lines.

Example

Here is an example how to create RadCartesianChart with ScatterSpline Series:

First, create the needed business objects, for example:

public class NumericalData
{
    public double XData { get; set; }
    public double YData { get; set; }
}

Then create a ViewModel:

Finally, use the following snippet to declare a RadCartesianChart with ScatterSpline Series in XAML and in C#:

<telerikChart:RadCartesianChart>
    <telerikChart:RadCartesianChart.BindingContext>
        <local:SeriesNumericalViewModel />
    </telerikChart:RadCartesianChart.BindingContext>
    <telerikChart:RadCartesianChart.HorizontalAxis>
        <telerikChart:NumericalAxis LabelFitMode="MultiLine" />
    </telerikChart:RadCartesianChart.HorizontalAxis>
    <telerikChart:RadCartesianChart.VerticalAxis>
        <telerikChart:NumericalAxis />
    </telerikChart:RadCartesianChart.VerticalAxis>
    <telerikChart:RadCartesianChart.Series>
        <telerikChart:ScatterSplineSeries XValueBinding="XData"
                                          YValueBinding="YData"
                                          ItemsSource="{Binding Data1}" />
        <telerikChart:ScatterSplineSeries XValueBinding="XData"
                                          YValueBinding="YData"
                                          ItemsSource="{Binding Data2}" />
    </telerikChart:RadCartesianChart.Series>
</telerikChart:RadCartesianChart>
var chart = new RadCartesianChart
{
    BindingContext = new SeriesNumericalViewModel(),
    HorizontalAxis = new NumericalAxis()
    {
        LabelFitMode = AxisLabelFitMode.MultiLine
    },
    VerticalAxis = new NumericalAxis(),
    Series =
    {
        new ScatterSplineSeries
        {
            XValueBinding = new PropertyNameDataPointBinding("XData"),
            YValueBinding = new PropertyNameDataPointBinding("YData")
        },
        new ScatterSplineSeries
        {
            XValueBinding = new PropertyNameDataPointBinding("XData"),
            YValueBinding = new PropertyNameDataPointBinding("YData")
        }
    }
};

chart.Series[0].SetBinding(ChartSeries.ItemsSourceProperty, "Data1");
chart.Series[1].SetBinding(ChartSeries.ItemsSourceProperty, "Data2");

Where the telerikChart namespace is the following:

xmlns:telerikChart="clr-namespace:Telerik.XamarinForms.Chart;assembly=Telerik.XamarinForms.Chart"
using Telerik.XamarinForms.Chart;

And here is the result:

Basic ScatterSplineSeries

A sample ScatterSpline Series example can be found in the Chart/Series folder of the SDK Samples Browser application.

Customization Example

    var series = new ScatterSplineSeries 
    { 
        Stroke = new Color(0.6, 0.6, 0.9), 
        StrokeThickness = 5 
    };
