是否有人有一些经验与图表的工作，在中？特别我想通过code来创建它们！

Does anybody have some experience working with charts, in ? Specially i want to create them by code!

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Windows.Forms.DataVisualization.Charting; using System.Diagnostics; namespace WindowsFormsApplication6 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { Random rnd = new Random(); Chart mych = new Chart(); mych.Series.Add("duck"); mych.Series["duck"].SetDefault(true); mych.Series["duck"].Enabled = true; mych.Visible = true; for (int q = 0; q < 10; q++) { int first = rnd.Next(0,10); int second = rnd.Next(0,10); mych.Series["duck"].Points.AddXY(first, second); Debug.WriteLine(first + " " + second); } mych.Show(); Controls.Add(mych); mych.Show(); } } }

我想要使用的.Net（.NET 4时，Visual Studio 2010）图...但随机生成的数据集，并没有出现。只有出现一个空白，图表，我认为。我GOOGLE了它，却只有例子和教程像这和，是与它的工作手册拖的方法。我不知道为什么没有出现数据。请帮忙。 随机的事情显然作品;

i'm trying to use .Net ( 4, Visual Studio 2010) chart... but the random generated data set, doesn't appears. Only appears a blank, chart i think. I googled it, but there is only examples and tutorials like this , and, yes with manual "drag" method it works. I have no idea why not appearing the data. Please help. The random thing apparently works;
