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.
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
Here's the result:
LineSeries extend CategoricalStrokedSeries which provide the following way to change their style:
- setStrokeColor(int): changes the color used to draw lines. In order to get the current value, use getStrokeColor().
- setStrokeThickness(float): changes the width of the lines. In order to get the current value, use getStrokeThickness().
You can also customize the appearance of LineSeries by using Palettes.
