c# - C# 折线图动态数据绑定

Question

我希望能够为此动态创建图表我使用名为的方法创建了以下类getChart()

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Controls.DataVisualization.Charting;
namespace Henvendelser
{
    class ChartDataCreator
    {
        private Dictionary<String, List<ContactQueue>> dataList;

        public ChartDataCreator() {

        }

        public Chart getChart(String choice) {

            Chart c = new Chart();
            LineSeries ls = new LineSeries();
            ls.IndependentValueBinding="{Binding Path=Key}";
            ls.DependentValueBinding="{Binding Path=Value}";
            ls.ItemsSource =

            new KeyValuePair<int, int>[]{
            new KeyValuePair<int,int>(1, 12),
            new KeyValuePair<int,int>(2, 25),
            new KeyValuePair<int,int>(3, 5),
            new KeyValuePair<int,int>(4, 6),
            new KeyValuePair<int,int>(5, 10),
            new KeyValuePair<int,int>(6, 4),
            new KeyValuePair<int,int>(7, 40),
            new KeyValuePair<int,int>(8, 12),
            new KeyValuePair<int,int>(9, 25),
            new KeyValuePair<int,int>(10, 5),
            new KeyValuePair<int,int>(11, 6),
            new KeyValuePair<int,int>(12, 10),
            new KeyValuePair<int,int>(13, 4),
            new KeyValuePair<int,int>(14, 8),
            new KeyValuePair<int,int>(15, 9),
            new KeyValuePair<int,int>(16, 50),
            new KeyValuePair<int,int>(17, 40) };
            c.Series.Add(ls);
            return c;
        }
    }
}

现在你可以看到我的代码有一个错误：

ls.IndependentValueBinding="{Binding Path=Key}"; ls.DependentValueBinding="{Binding Path=Value}";

我的问题是如何动态设置独立和依赖绑定。另外请指出我是否还缺少其他东西以使其正常工作。

试试这个，他们正在寻找绑定对象，这就是你必须提供的。

Chart c = new Chart();
LineSeries ls = new LineSeries();
// For new binding you provide it the string path to your property.
Binding bindInd = new Binding("Key");
Binding bindDep = new Binding("Value");
// then you can set the properties of your binding like so
bindInd.Source = <your source>;
bindDep.Source = <Your Source>;
bindDep.Mode = BindingMode.OneWay;
bindInd.Mode = BindingMode.OneWay;
ls.IndependentValueBinding = bindInd;
ls.DependentValueBinding =bindDep;
