样例代码j包括实时曲线图，多种线性图集中显示以及柱形图、饼形图、线形图等使用和介绍，并有代码注解，非常适合学习者。 public partial class Form3 : Form { Random ran = new Random(); PointPairList list1 = new PointPairList(); PointPairList list2 = new PointPairList(); LineItem myCurve; public Form3() { InitializeComponent(); } private void Form3_Load(object sender, EventArgs e) { this.zedGraphControl1.GraphPane.Title.Text = "动态折线图"; this.zedGraphControl1.GraphPane.XAxis.Title.Text = "时间"; this.zedGraphControl1.GraphPane.YAxis.Title.Text = "数量"; this.zedGraphControl1.GraphPane.XAxis.Type = ZedGraph.AxisType.DateAsOrdinal; //开始的时候是空的，随着时间的推移才逐渐画满，可以在初始化的时候填几个Y坐标为0的点 for (int i = 0; i = 100) { list1.RemoveAt(0); } if (list2.Count >= 100) { list2.RemoveAt(0); } zedGraphControl1.GraphPane.XAxis.Scale.MaxAuto = true; double x = (double)new XDate(DateTime.Now); double y = ran.Next(100, 120); double y2 = ran.Next(90, 150); // int RandKey = ran.Next(100, 999); list1.Add(x, y);
