WinRTXamlToolkit在Win8.1实现统计图

【注1】WinRTXamlToolkit是免费控件，不过很久不更新了，而且网上的资源很少。后来我发现syncfusion控件有免费的community版本，并且有详细文档，所以就转过去使用syncfusion了。继续在WinRT/UWP奋战的亲们可以去围观一下：https://www.syncfusion.com/products/communitylicense

【注2】.Net平台各种免费和收费的包含Chart的控件：WinRTXamlToolkit/ModernUI/Visifire/Telerik/Syncfusion

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">

    </Grid>

        public class FinancialStuff
        {
            public string Name { get; set; }
            public int Amount { get; set; }
        }

        private void LoadChartContents()
        {
            Random rand = new Random();
            List<FinancialStuff> financialStuffList = new List<FinancialStuff>();
            financialStuffList.Add(new FinancialStuff() { Name = "MSFT", Amount = rand.Next(0, 200) });
            financialStuffList.Add(new FinancialStuff() { Name = "AAPL", Amount = rand.Next(0, 200) });
            financialStuffList.Add(new FinancialStuff() { Name = "GOOG", Amount = rand.Next(0, 200) });
            financialStuffList.Add(new FinancialStuff() { Name = "BBRY", Amount = rand.Next(0, 200) });
            (PieChart.Series[0] as PieSeries).ItemsSource = financialStuffList;
            (ColumnChart.Series[0] as ColumnSeries).ItemsSource = financialStuffList;
            (LineChart.Series[0] as LineSeries).ItemsSource = financialStuffList;
            (BarChart.Series[0] as BarSeries).ItemsSource = financialStuffList;
            (BubbleChart.Series[0] as BubbleSeries).ItemsSource = financialStuffList;
        }
    

也可以先将Series弄出来：

        public static LineSeries InitChart(List<FinancialStuff> financialStuffList)
        {
            LineSeries lSeries = new LineSeries();
            lSeries.IndependentValuePath = "Name";
            lSeries.DependentValuePath = "Amount";

            lSeries.ItemsSource = financialStuffList;

            return lSeries;
        }

 LineSeries ls = Functions.WinrtChartHelper.InitChart(financialStuffList);
                    this.LineChart.Series.Add(ls);

然而，这样子只能实现LineSeries ，PieSeries/ColumnSeries/BarSeries/BubbleSeries等都会有一个UnhandledException出现……
