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; }


    }
