C#折线图动态数据绑定

我希望能够为此动态创建图表。我用一个名为getChart()
的方法创建了以下类
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,正如你所看到的,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绑定和依赖绑定。此外,请指出我是否遗漏了其他东西,以便使其发挥作用。
试试这个,他们正在寻找绑定对象,所以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;
