場景
在使用ZedGraph時，經常有圖形選項功能，設定曲線圖相關屬性后，
點擊保存會設定另一個表單的屬性并重繪圖，
效果
實作
在設定圖形的選項的類中，宣告委托和事件
//委托的定義public delegate void ReloadPanelDelegete();//事件宣告public static event ReloadPanelDelegete reloadPanelEvent;
在當前表單的確定按鈕的點擊事件中
將相關曲線圖的Y軸以及X軸的相關屬性存到xml組態檔中，然后呼叫方法
去重繪曲線圖，使其重新加載，
private void confirmbButton_Click(object sender, EventArgs e) { #region 獲取X軸的屬性并賦值給XAxisModel //對X軸的屬性組態檔進行保存 //根據控制元件的 System.Windows.Forms.Control.Name 屬性搜索控制元件并生成由所有匹配項組成的陣列， //如果搜索所有子控制元件，則為 true；否則為 false， XAxisModel xAxisModel = new XAxisModel(); //獲取標題 RadioGroup radioGroupX = this.Controls.Find("radioGroupX", true)[0] as RadioGroup; xAxisModel.Title = radioGroupX.Text; //獲取下限 TextEdit minTextEditX = this.Controls.Find("minTextEditX", true)[0] as TextEdit; xAxisModel.Min = Double.Parse(minTextEditX.Text); //獲取上限 TextEdit maxTextEditX = this.Controls.Find("maxTextEditX", true)[0] as TextEdit; xAxisModel.Max = Double.Parse(maxTextEditX.Text); //獲取顏色 ColorEdit colorEditX = this.Controls.Find("colorEditX", true)[0] as ColorEdit; xAxisModel.Color = colorEditX.Text; #endregion #region 將X軸的屬性存到組態檔中 Boolean isWriteX = ChartOptionHelper.setXAxisAttribute(xAxisModel); #endregion #region 獲取Y軸屬性并賦值給List<YAxisModel> List<YAxisModel> yAxisModelList = new List<YAxisModel>(); for (int i = 1; i <= yAxisCount; i++) { YAxisModel yAxisModel = new YAxisModel(); //獲取標題 RadioGroup radioGroupY = this.Controls.Find("radioGroupY" + i, true)[0] as RadioGroup; yAxisModel.Title = radioGroupY.Text; //獲取下限 TextEdit minTextEditY = this.Controls.Find("minTextEditY" + i, true)[0] as TextEdit; yAxisModel.Min = Double.Parse(minTextEditY.Text); //獲取上限 TextEdit maxTextEditY = this.Controls.Find("maxTextEditY" + i, true)[0] as TextEdit; yAxisModel.Max = Double.Parse(maxTextEditY.Text); //獲取顏色 ColorEdit colorEditY = this.Controls.Find("colorEditY" + i, true)[0] as ColorEdit; yAxisModel.Color = colorEditY.Text; yAxisModelList.Add(yAxisModel); } #endregion #region 將Y軸的屬性存到組態檔中 Boolean isWriteY = ChartOptionHelper.setYAxisAttribute(yAxisModelList); #endregion #region 彈出對話框并設定點擊確定之后的事件 if (isWriteX == true && isWriteY == true) { if (this.Confirm("保存成功") == DialogResult.OK) { //將是否第一次打開軟體的標識量改為0，,下次打開直接讀取組態檔 Global.isFirstOpen = 0; if (reloadPanelEvent != null) { reloadPanelEvent(); } this.Dispose(); } } else { DevExpress.XtraEditors.XtraMessageBox.Show("保存失敗", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question); } #endregion }
然后在曲線圖顯示的表單中訂閱事件
Dialog.ChartOption.reloadPanelEvent += new Dialog.ChartOption.ReloadPanelDelegete(reloadPanel);
其中左邊的類是上面圖形選項的類，右邊的類是表單顯示的類
然后在表單顯示的類中新建圖上面ReloadPanelDelegete的引數同名的方法reloadPanel實作曲線圖的重繪，
public void reloadPanel() { //宣告pane物件 GraphPane myPane = new GraphPane(); //獲取控制元件的Pane myPane = this.zedGraphControl1.GraphPane; #region 從組態檔中加載并設定X軸屬性 //獲取X軸屬性 XAxisModel xAttribute = ChartOptionHelper.getXAxisAttribute(Global.RADIO_GROUP_YAXIS_FILEPATH_X);

注：
1.mypane是ZedGraph的面板，其默認是有一條Y軸物件的，為myPane.YAxis
2.如果要顯示第二條Y軸，ZedGraph是默認存在第二條Y軸的，為myPane.Y2Axis，不過就是默認不顯示，要使其顯示，需要myPane.Y2Axis.IsVisible = true;
3.如果是三條以上Y軸的話，就要使用
myPane.YAxisList.Add(yAxisNew);
加入其Y軸的list，
4.這里的需求是首次打開默認加載一條Y軸，所以在首次加載時判斷
myPane.YAxisList.Count == 1，其自己的List是否為1，為1則代表是首次加載，下次再設定并加載時，其list就不為1了，所以需要是設定，而不是再往list中新增了，
5.需要注意的是，如果顯示4條Y軸的話，其myPane.YAxisList.Count為3，,一條是不算在內的，
6.重繪曲線圖的代碼
this.zedGraphControl1.Invalidate();
