本文实例讲述了DevExpress中ChartControl实现柱状图演示的方法。分享给大家供大家参考。具体实现方法如下：

关键代码如下：

namespace DevExpressChart
{
    public partial class winProduct : Form
    {
        public winProduct()
        {
            InitializeComponent();
        }
        static readonly string AccessFullPath = string.Format(@\"{0}\\Northwind.MDB\", AppDomain.CurrentDomain.BaseDirectory);
        static DataTable ProductList = null;
        AccessUtilsV2 AccessHelper = null;
        private void winChat_Load(object sender, EventArgs e)
        {
            AccessHelper = new AccessUtilsV2(AccessFullPath);
            ProductList = AccessHelper.ExecuteDataTable(\"select * from Products\", null);
            BuilderDevChart();
        }
        private void BuilderDevChart()
        {
            if (ProductList != null)
            {
                Series _barSeries = new Series(\"测试\", ViewType.Bar);
                _barSeries.ArgumentDataMember = \"ProductName\";//x轴
                _barSeries.ValueDataMembers[0] = \"UnitPrice\";//Y轴
                _barSeries.DataSource = ProductList;
                _barSeries.AddDataFilter(\"CategoryID\", 4, DataFilterCondition.Equal);
                _barSeries.SetColorEach(true);
                chartControl1.Series.Add(_barSeries);
                _barSeries.LegendPointOptions.PointView = PointView.ArgumentAndValues;

                //chartControl1.SeriesDataMember = \"UnitPrice\";
                //chartControl1.SeriesTemplate.ValueDataMembers[0] = \"UnitPrice\";
                //chartControl1.SeriesTemplate.ArgumentDataMember = \"ProductName\";
                //chartControl1.SeriesTemplate.ArgumentScaleType = ScaleType.Qualitative;
                //chartControl1.SeriesTemplate.AddDataFilter(\"CategoryID\", 4, DataFilterCondition.Equal);
                //chartControl1.SeriesTemplate.LegendPointOptions.PointView = PointView.ArgumentAndValues;
                chartControl1.SetXLableAngle(-35);
                chartControl1.SetCrosshair(true);

                chartControl1.Legend.Direction = LegendDirection.LeftToRight;
                chartControl1.Legend.AlignmentHorizontal = LegendAlignmentHorizontal.Center;
                chartControl1.Legend.AlignmentVertical = LegendAlignmentVertical.BottomOutside;
                chartControl1.DataSource = ProductList;

                chartControl1.AddTitle(\"Product List\");
                //--------------------------
            }
        }
    }
}
