如何以编程方式添加ZedGraph？

Question

当我点击一个按钮时，我想添加一个ZedGraph，但是当我点击我的按钮时ZedGraph不会出现。这里是我的按钮单击处理程序：

ZedGraphControl zg1 = new ZedGraphControl(); 
zg1.Dock = DockStyle.Fill; 
GraphPane myPane = new GraphPane(); 
BarItem myBar = new BarItem("Bar1"); 
myBar.AddPoint(1, 10); 
myBar.AddPoint(2, 20); 
myBar.Bar.Fill = new Fill(Color.AliceBlue, Color.White, Color.AliceBlue); 
zg1.AxisChange(); 
zg1.Invalidate(); 

zg1.Show(); 

Answer 1

，在跳出我最主要的是，我没有看到你adding your new Control到Container对象羯羊它是一个Form或Panel。另外你是不是你的Pane或您Bar您ZedGraphControl

尝试这样的事情

ZedGraphControl zg1 = new ZedGraphControl(); 
zg1.Dock = DockStyle.Fill; 
zg1.GraphPane = new GraphPane(); 

BarItem myBar = new BarItem("Bar1"); 
myBar.AddPoint(1, 10); 
myBar.AddPoint(2, 20); 
myBar.Bar.Fill = new Fill(Color.AliceBlue, Color.White, Color.AliceBlue); 

zg1.GraphPane.CurveList.Add(myBar); 


zg1.AxisChange(); 
zg1.Invalidate(); 

zg1.Show(); 
this.Controls.Add(zg1);
