Winform中跨窗体设置Zedgraph的属性并刷新曲线图
<h1>场景</h1><p>在利用ZedGraph时，常常有图形选项功能，设置曲线图相干属性后，</p>
<p>点击生存会设置另一个窗体的属性并刷新图。</p>
<h2>结果</h2>
<p><div align="center"></div></p>
<p> </p>
<p></p>
<p> </p>
<p>实现</p>
<p>在设置图形的选项的类中，声明委托和事件</p>
//委托的界说
public delegate void ReloadPanelDelegete();
//事件声明
public static event ReloadPanelDelegete reloadPanelEvent;
<p> </p>
<p>在当前窗体简直定按钮的点击事件中</p>
<p>将相干曲线图的Y轴以及X轴的相干属性存到xml设置文件中，然后调用方法</p>
<p>去刷新曲线图，使其重新加载。</p>

<p>注：</p>
<p>1.mypane是ZedGraph的面板，其默认是有一条Y轴对象的，为myPane.YAxis</p>
<p>2.如果要显示第二条Y轴，ZedGraph是默认存在第二条Y轴的，为myPane.Y2Axis，不外就是默认不显示，要使其显示，须要myPane.Y2Axis.IsVisible
= true;</p>
<p>3.如果是三条以上Y轴的话，就要利用</p>
myPane.YAxisList.Add(yAxisNew);
<p> </p>
<p>加入其Y轴的list。</p>
<p>4.这里的需求是初次打开默认加载一条Y轴，以是在初次加载时判断</p>
<p>myPane.YAxisList.Count ==
1，其本身的List是否为1，为1则代表是初次加载，下次再设置并加载时，其list就不为1了。以是须要是设置，而不是再往list中新增了。</p>
<p>5.须要注意的是，如果显示4条Y轴的话，其myPane.YAxisList.Count为3，,一条是不算在内的。</p>
<p>6.刷新曲线图的代码</p>
this.zedGraphControl1.Invalidate();
