ChartView for Xamarin.Android: LineSeries

RadCartesianChartView visualizes each data item from the LineSeries and connects them with straight line segments. The LineSeries extend CategoricalStrokedSeries, so they are also CategoricalSeries and require one CategoricalAxis and one LinearAxis.

Example

You can read from the Getting Started page how to define the MonthResult type and declare the initData() method.

After you create the method for initialization of sample data, you can create a RadCartesianChartView with LineSeries by adding the following code to the onCreate() method of your Activity.

InitData();

RadCartesianChartView chartView = new RadCartesianChartView(this);

LineSeries lineSeries = new LineSeries();
lineSeries.CategoryBinding = new MonthResultDataBinding ("Month");
lineSeries.ValueBinding = new MonthResultDataBinding ("Result");
lineSeries.Data = (Java.Lang.IIterable)this.monthResults;
chartView.Series.Add(lineSeries);

CategoricalAxis horizontalAxis = new CategoricalAxis();
chartView.HorizontalAxis = horizontalAxis;

LinearAxis verticalAxis = new LinearAxis();
chartView.VerticalAxis = verticalAxis;

ViewGroup rootView = (ViewGroup)FindViewById(Resource.Id.container);
rootView.AddView(chartView);

This example assumes that your root container has id container

Here's the result:

Customization

LineSeries extend CategoricalStrokedSeries which provide the following way to change their style:

• StrokeColor: changes the color used to draw lines.
• StrokeThickness: changes the width of the lines.

You can also customize the appearance of LineSeries by using Palettes.
