Silverlight动态创建Chart

1. 在Home.xaml文件中，加入Chart控件

<chartingToolkit:Chart x:Name="TestChart" Background= "AliceBlue"  Height="600">

2. 在Home.xaml.cs中，写如下代码：（以AreaChart为例，前提必须先有一个List类型的数据源，怎样添加数据源，参看前一篇Blog）

//绑定数据源到图标

private void BindListtochart(List<ProductionData> list)

{

                //设置图名称，TestChart是前台控件的X:Name属性设置的，必须一致

                TestChart.Title = "石油天然气产量、销量、消耗图";
                //创建X轴，这个方法是从网上copy的，其实直接写成创建Y轴的方式就行了，更简单易懂

                //X轴可以创建成DataTimeAxis, CategoryAxis等等类型，显示的形式不同，可参考自带Document
                Action<Chart> chartModifier = (chart) =>
                {
                    DateTimeAxis XAxis = new DateTimeAxis { Orientation = AxisOrientation.X,Title = "月份",FontStyle = FontStyles.normal,FontSize = 8 };
                    XAxis.IntervalType = DateTimeIntervalType.Months;
                    XAxis.Interval = 1;
                    XAxis.ShowGridLines = true;

                    TestChart.Axes.Add(XAxis);                 
                };

                chartModifier(TestChart);      

                       
                //创建Y轴1
                Linearaxis YAxis1 = new Linearaxis { Orientation = AxisOrientation.Y,Location = AxisLocation.Right,Title = "天然气香港销量",ShowGridLines = false };
                YAxis1.Orientation = AxisOrientation.Y;                
                TestChart.Axes.Add(YAxis1);

                //创建数据系列，并绑定数据源
                AreaSeries areaSeries1 = new AreaSeries();
                areaSeries1.Title = "香港";  //图例显示的文字
                areaSeries1.ItemsSource = list;  //数据源绑定
                areaSeries1.IndependentValueBinding = new System.Windows.Data.Binding("DATE"); //绑定字段
                areaSeries1.DependentValueBinding = new System.Windows.Data.Binding("GAS_HKT_SALES");
                
                areaSeries1.DependentRangeAxis = YAxis1;

                TestChart.Series.Add(areaSeries1);

} //结束
