### 如何在 WinForms 应用程序中使用 ZedGraph 绘制图表
#### 添加 ZedGraph 到项目
为了能够在 C# 的 WinForms 应用程序中使用 ZedGraph,首先需要将 ZedGraph 控件添加到工具箱并将其拖放到窗体上。这可以通过 NuGet 包管理器来完成安装操作[^2]。
```csharp
// 使用Nuget包管理器控制台命令安装ZedGraph
Install-Package ZedGraph
```
#### 创建基本的折线图实例
一旦成功引入了 ZedGraph 库之后,在设计视图下可以找到 `ZedGraphControl` 控件,并把它放置于所需位置。下面是一个简单的例子展示怎样构建一条直线图形:
```xml
<Window x:Class="YourNamespace.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<!-- 将此控件放入XAML布局 -->
<zedgraph:ZedGraphControl x:Name="zedGraphControl"/>
</Grid>
</Window>
```
接着初始化该控件以及配置其属性以便能够正常工作:
```csharp
using System;
using System.Windows.Forms;
using ZedGraph;
public partial class MainForm : Form {
public MainForm() {
InitializeComponent();
GraphPane myPane = zedGraphControl.GraphPane;
myPane.Title.Text = "Sample Line Chart";
myPane.XAxis.Title.Text = "X Axis Label";
myPane.YAxis.Title.Text = "Y Axis Label";
PointPairList list = new PointPairList(); // 来源于ZedGraph.dll文件里的数据结构[^4]
Random rand = new Random();
for (int i=0;i<=10;++i){
double x=i*rand.NextDouble()*Math.PI;
double y=Math.Sin(x);
list.Add(x,y);
}
LineItem curve = myPane.AddCurve("Sine Wave",list,COLOR.Blue,SymbolType.Circle);
zedGraphControl.AxisChange();
this.Controls.Add(zedGraphControl);
}
}
```
这段代码实现了在一个窗口内创建一个带有正弦波形的新曲线对象,并设置了相应的标签文字给 X 和 Y 轴。最后调用了 `AxisChange()` 方法刷新界面使更改生效[^3]。
对于更复杂的场景比如多条 Y 轴的情况,则可以根据需求调整坐标轴的位置和样式[^5]。
