tookit chart 一个简单的双Y轴实现

最近在项目中需要使用到 toolkit里面的chart组件 下面是一个简单的例子和双Y轴的实现

后台代码

public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();

List<CityEntity> pugetSound = new List<CityEntity>();
pugetSound.Add(new CityEntity { Key = "Bellevue", Value = 1 });
pugetSound.Add(new CityEntity { Key = "Issaquah", Value = 2 });
pugetSound.Add(new CityEntity { Key = "Redmond", Value = 3 });
pugetSound.Add(new CityEntity { Key = "Seattle", Value = 4 });

ColumnSeries series = new ColumnSeries();
series.ItemsSource = pugetSound;
series.DependentValueBinding = new Binding("Value");
series.IndependentValueBinding = new Binding("Key");
series.Title = "柱图";
series.DependentRangeAxis = new LinearAxis() { Orientation = AxisOrientation.Y, Minimum = 0, Maximum = 10 };
this.Chart.Series.Add(series);

LineSeries series2 = new LineSeries();
series2.ItemsSource = pugetSound;
series2.DependentValueBinding = new Binding("Value");
series2.IndependentValueBinding = new Binding("Key");
series2.Title = "趋势图";
series2.DependentRangeAxis = new LinearAxis() { Orientation = AxisOrientation.Y, Minimum =0, Maximum = 10 };
this.Chart.Series.Add(series2);
}

}

public class CityEntity
{
public string Key { get; set; }
public int Value { get; set; }

}
