WPF DevExpress控件绑定数据源

<dxc:ChartControl Name="chartControl1">
            <dxc:ChartControl.Diagram>
                <dxc:XYDiagram2D DataContext="{Binding Test.Data}">
                    <dxc:XYDiagram2D.Series>
                        <dxc:BarSideBySideSeries2D DisplayName="First Series" DataContext="{Binding Test.Data}" BarWidth="0.5">
                            <dxc:BarSideBySideSeries2D.Points>
                                <dxc:SeriesPoint Argument="A" Value="1" />
                                <dxc:SeriesPoint Argument="B" Value="2" />
                                <dxc:SeriesPoint Argument="C" Value="3" />
                                <dxc:SeriesPoint Argument="D" Value="4" />
                            </dxc:BarSideBySideSeries2D.Points>
                        </dxc:BarSideBySideSeries2D>                    </dxc:XYDiagram2D.Series>
                </dxc:XYDiagram2D>
            </dxc:ChartControl.Diagram>
            <dxc:ChartControl.Legend>
                <dxc:Legend />
            </dxc:ChartControl.Legend>
        </dxc:ChartControl>我现在只能写到这儿，至于它每一个柱状图的SeriesPoint 怎么去绑定我Test.Data中的键值对就不会了……其中Test是我自定义的一个测试类，里面只有一个Data属性，也就是我要绑定的数据源，是个IDictionary<string, int>类型的属性

它的Demo都是写死的数据啊，不是一个数据对象……

给你看看另一个报表工具赋值数据源的方法，希望能对你参考价值。
public void CreateChart(RenderAs renderType)
        {
            string chartTitle = "";
            string axisYTtitle = "";
            string legendTtitle = "";
            if (currentTrace.TraceType == CommonSignatureEventsBLM.BinaryTraceTypes.Torque)
            {
                chartTitle = String.Format("输出编号:{0} - 类型:扭矩/时间 - 输出点数:{1}", currentTrace.TraceNumber.ToString(), currentTrace.TracePoints.Length.ToString());
                axisYTtitle = "Nm";
                legendTtitle = "扭矩/时间曲线";
            }
            else if (currentTrace.TraceType == CommonSignatureEventsBLM.BinaryTraceTypes.Angle)
            {
                chartTitle = String.Format("输出编号:{0} - 类型:角度/时间 - 输出点数:{1}", currentTrace.TraceNumber.ToString(), currentTrace.TracePoints.Length.ToString());
                axisYTtitle = "Deg.(°)";
                legendTtitle = "角度/时间曲线";
            }            Chart chart = new Chart();
            chart.AnimationEnabled = false;
            chart.BorderThickness = new Thickness(1, 0, 0, 1);
            setBackgroundBrush(chart); //设置背景颜色

            chart.ScrollingEnabled = false;
            chart.View3D = false;

            Title title = new Title();
            title.Text = chartTitle;
            chart.Titles.Add(title);

            Axis charAxisX = new Axis();
            Axis charAxisY = new Axis();

            charAxisX.Title = "ms";
            chart.AxesX.Add(charAxisX);//为图表添加一个AxesX            charAxisY.Title = axisYTtitle;
            charAxisY.AxisMinimum = (int)getMinY(currentTrace.TracePoints);
            addGridLine(charAxisX);
            chart.AxesY.Add(charAxisY);//我图表添加一个AxesY
                         DataSeries dataSeries = new DataSeries();            dataSeries.ToolTipText = "";
            dataSeries.LegendText = legendTtitle;
            dataSeries.RenderAs = renderType; //Column
            dataSeries.XValueType = ChartValueTypes.Numeric;

            DataPoint dataPoint;            for (int i = 0; i < currentTrace.TracePoints.Length; i++)
            {
                dataPoint = new DataPoint();
                dataPoint.XValue = currentTrace.TracePoints[i].X;
                dataPoint.YValue = currentTrace.TracePoints[i].Y;
                dataSeries.DataPoints.Add(dataPoint);
            }             //增加一个图
            chart.Series.Add(dataSeries);

            //最终获得的扭矩值              chart.Series.Add(addPoint()); //添加坐标点所在的线
            grid_main.Children.Add(chart);

        }

又给你扒拉出一个文章，以后dev的问题都可以去它网站上，看https://www.devexpress.com/Support/Center/Example/Details/E1060

只从界面上绑定，lz应该先去看看DataContext，Binding，ObservableCollection，INotifyPropertyChanged等

对了，还有ItemsSource试过了，没头绪……

现在可以通过指定数据源的方式进行绑定了，后台代码是： #region 创建测试用的数据源
            DataTable newdtb = new DataTable();
            newdtb.Columns.Add("Id", typeof(int));
            newdtb.Columns.Add("ProName", typeof(string));
            newdtb.Columns.Add("ProPrice", typeof(decimal));
            newdtb.Columns.Add("Trade_Date", typeof(string));
            newdtb.Columns["Id"].AutoIncrement = true;            //表记录
            Random ran = new Random();
            for (int i = 1; i < 10; i++)
            {                int RandKey = ran.Next(10, 9999);//10~9999之间的数
                decimal dBase = Convert.ToDecimal(ran.NextDouble());//0~1之间的任意数
                DataRow newRow = newdtb.NewRow();
                newRow["Trade_Date"] = i.ToString() + "月";
                newRow["ProPrice"] = Convert.ToDecimal((RandKey * dBase).ToString("0.0#"));
                newdtb.Rows.Add(newRow);
            }
            #endregion            //指定Chart控件的DataSource数据源
            chartControl1.DataSource = newdtb.DefaultView;
然后在界面上直接绑定需要显示的值就可以了，指定每个柱子的ArgumentDataMember，即X轴，还有ValueDataMember，即Y轴，还有就是SeriesDataMember，即柱状图左边的注释部分：<dxc:ChartControl Name="chartControl1">
            <dxc:ChartControl.Diagram>
                <dxc:XYDiagram2D SeriesDataMember="Trade_Date">
                    <dxc:XYDiagram2D.SeriesTemplate>
                        <dxc:BarSideBySideSeries2D ArgumentDataMember="Trade_Date" ValueDataMember="ProPrice" />
                    </dxc:XYDiagram2D.SeriesTemplate>
                    <dxc:XYDiagram2D.AxisX>
                        <dxc:AxisX2D>
                        </dxc:AxisX2D>
                    </dxc:XYDiagram2D.AxisX>
                </dxc:XYDiagram2D>
            </dxc:ChartControl.Diagram>
            <dxc:ChartControl.Legend>
                <dxc:Legend />
            </dxc:ChartControl.Legend>
        </dxc:ChartControl>
