DevExpress 柱状图

通过构造函数，把值传递过来

   public XtraInterpreterChartForm(object ds)
         {
             InitializeComponent();
             datasource = ds;
         }

设置形状，数据等：

  // Create a pie series.
             Series series1 = new Series("Bar Series 1", ViewType.Bar);
             chartControl1.Series.Add(series1);
             chartControl1.DataSource = datasource;

             // Adjust the value numeric options of the series.
             series1.ArgumentDataMember = "Username";
             series1.ValueDataMembers.AddRange(new string[] { "WordCount" });

             ((BarSeriesView)series1.View).ColorEach = true;
             series1.LegendPointOptions.Pattern = "{A}";

             // Add a title to the chart and hide the legend.
             ChartTitle chartTitle1 = new ChartTitle {Text = "译员剩余字数信息"};
             chartControl1.Titles.Add(chartTitle1);
             chartControl1.Legend.Visible = true;

             // Add the chart to the form.
             chartControl1.Dock = DockStyle.Fill;
             Controls.Add(chartControl1);
