易采站长站为您分析DevExpress中ChartControl实现柱状图演示方法,实例展示了相关绘图函数的具体用法,具有一定的实用价值,需要的朋友可以参考下    

本文实例讲述了DevExpress中ChartControl实现柱状图演示的方法。。具体实现方法如下：

关键代码如下：

 

复制代码 using System;
using System.Data;
using System.Windows.Forms;
using CSharpUtilHelpV2;
using DevExpress.XtraCharts;

 

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;
