實作
首先在ZedGraph的右鍵選單中添加設定曲線顏色選項，在面板初始化的方法中訂閱右鍵事件，
zgc.ContextMenuBuilder -= zgc_ContextMenuBuilder; //背景關系選單生成事件訂閱zgc.ContextMenuBuilder += zgc_ContextMenuBuilder; //背景關系選單生成事件訂閱
然后在訂閱的方法中
private static void zgc_ContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip, Point mousePt, ZedGraphControl.ContextMenuObjectState objState) { #region 擴展背景關系選單 #region 圖形選項選單 ToolStripMenuItem mnuChartOption = new ToolStripMenuItem(); //新建選單項物件 mnuChartOption.Name = "set_curve_color"; mnuChartOption.Text = "設定曲線顏色"; //點擊彈出圖形選項對話框 mnuChartOption.Click += delegate(object sender, EventArgs e) { if (curveModelList == null || curveModelList.Count == 0) { XtraMessageBox.Show("當前沒有曲線"); } else { FrmSetCurveColor setCurveColor = new FrmSetCurveColor(); DialogResult result = setCurveColor.ShowDialog(); //顯示Dialog if (result == DialogResult.OK) { TriggerSetCurveColor(); XtraMessageBox.Show("設定曲線顏色成功"); } } }; menuStrip.Items.Add(mnuChartOption); //把圖形選項對話框添加到背景關系選單中 #endregion #endregion #region 漢化背景關系選單中的選單項 foreach (ToolStripMenuItem item in menuStrip.Items) { switch (item.Name) { case "copied_to_clip": item.Text = @"復制到剪貼板"; break; case "copy": item.Text = @"復制"; break; case "page_setup": item.Text = @"頁面設定..."; break; case "print": item.Text = @"列印..."; break; case "save_as": item.Text = @"另存圖表..."; break; case "set_default": item.Text = @"恢復默認大小"; break; case "show_val": item.Text = @"顯示節點數值"; break; case "title_def": item.Text = @"標題"; break; case "undo_all": item.Text = @"還原所有縮放"; break; case "unpan": item.Text = @"還原上一步縮放"; break; case "unzoom": item.Text = @"還原縮放"; break; case "set_curve_color": item.Text = @"設定曲線顏色"; break; } } #endregion }
此時會漢化右鍵選單并添加右鍵選項，并且其點擊事件是打開設定曲線顏色面板，
在設定曲線顏色面板的代碼中，在其load方法中呼叫初始化面板的方法，
此時要根據傳遞的曲線的Model的list去生成當前已有曲線的設定的panel，
那么當前已經有多少個曲線是如何傳遞的？
在前面ZedGraph生成曲線的地方所在的工具類中宣告一個全域的list
public static List<CurveModel> curveModelList= new List<CurveModel>();
其中CurveModel是自定義的存取曲線屬性的Model類
public class CurveModel { /// <summary> /// 曲線序號 /// </summary> private int curveIndex; public int CurveIndex { get { return curveIndex; } set { curveIndex = value; } } /// <summary> /// 源檔案 /// </summary> private string originFile; public string OriginFile { get { return originFile; } set { originFile = value; } } /// <summary> /// 源檔案完整路徑 /// </summary> private string originFileFullPath; public string OriginFileFullPath { get { return originFileFullPath; } set { originFileFullPath = value; } } /// <summary> /// 屬性名 /// </summary> private string attributeName; public string AttributeName { get { return attributeName; } set { attributeName = value; } } /// <summary> /// 顏色 /// </summary> private string color; public string Color { get { return color; } set { color = value; } } }
宣告完list后，其中生成曲線的地方也在這個工具類中
curveModelList.Clear(); int curveIndex = 0; for (int k = 0; k < compTestDataList.Count; k++) { //回圈添加曲線 for (int i = 0; i < yList.Count; i++) { SymbolType symbolType = GetCurveSimple(yList[i].CurveType); //根據組態檔中曲線符號型別回傳曲線符號標識 list = SetCurveText(interval, xAttribute.TitleKey, yList[i].TitleKey, compTestDataList[k]); LineItem myCurve = myPane.AddCurve(yList[i].Title, list, System.Drawing.ColorTranslator.FromHtml(yList[i].Color), symbolType); myCurve = SetCurveType(myCurve,symbolType, yList[i].Type, yList[i].Color); //根據組態檔設定曲線型別 myCurve.YAxisIndex = i; //很關鍵，對應使用那個坐標值 CurveModel curveModel = new CurveModel(); string originFile = compTestDataList[k].ThisDataFile; curveModel.OriginFile = originFile.Substring(originFile.LastIndexOf("\\") + 1); curveModel.CurveIndex = curveIndex; curveModel.OriginFileFullPath = originFile; curveModel.AttributeName = yList[i].Title; curveModel.Color = yList[i].Color; curveModelList.Add(curveModel); curveIndex++; } }
這樣在生成曲線時就將當前圖形的所有曲線的屬性存到一個工具類中全域的一個list中，然后在設定曲線顏色面板中獲取這個list，
private void FrmSetCurveColor_Load(object sender, EventArgs e) { curveModelList.Clear(); curveModelList = ChartCompareHelper.curveModelList; initSetCurveColorPane(curveModelList); }
然后在使用這個list去初始化設定顏色的面板
private void initSetCurveColorPane(List<CurveModel> curveModelList) { int panelControlHeight = 20; int panelControlWidth = 50; foreach(CurveModel curve in curveModelList) { PanelControl panelControl = new PanelControl(); #region 生成一個Label標識X軸 //生成一個Label標識X軸 LabelControl label = new LabelControl(); label.Text = "第" + (curve.CurveIndex + 1).ToString() + "條曲線（" + curve.OriginFile + "的" + curve.AttributeName + "）的顏色為："; label.Location = new Point(Global.NOGROUP_HORIZONTAL_DISTANCE, Global.GROUP_VERTICAL_DISTANCE); label.Parent = panelControl; #endregion #region 生成一個顏色選擇器 //添加顏色選擇器 ColorEdit colorEditX = new ColorEdit(); colorEditX.Text = curve.Color; colorEditX.Width = Global.CHART_OPTION_WIDTH; colorEditX.Location = new Point(Global.NOGROUP_HORIZONTAL_DISTANCE * 2 + label.Width, Global.GROUP_VERTICAL_DISTANCE); colorEditX.Parent = panelControl; colorEditX.Name = "colorEdit"+curve.CurveIndex; #endregion #region 設定X軸Panel的位置以及屬性 //設定panel的寬度 panelControl.Width = label.Width + colorEditX.Width + Global.NOGROUP_HORIZONTAL_DISTANCE * 3; //設定panel的高度 panelControl.Height = label.Height + Global.GROUP_VERTICAL_DISTANCE * 2; panelControlHeight = panelControl.Height; panelControlWidth = panelControl.Width; //設定panel的位置 panelControl.Location = new Point(Global.NOGROUP_HORIZONTAL_DISTANCE, (panelControl.Height * curve.CurveIndex) + (Global.GROUP_VERTICAL_DISTANCE *(curve.CurveIndex + 1))); //設定Name panelControl.Name = "panelControl" + curve.CurveIndex; //將panel添加到當前表單 this.Controls.Add(panelControl); #endregion } this.Width = panelControlWidth + Global.NOGROUP_HORIZONTAL_DISTANCE * 4; this.Height = (curveModelList.Count + 1) * panelControlHeight + (curveModelList.Count + 2) * Global.GROUP_VERTICAL_DISTANCE + +this.panelControl1.Height; }
然后設定顏色后，點擊保存后在確定按鈕的點擊事件中
private void simpleButton2_Click_1(object sender, EventArgs e) { for (int i = 0; i < curveModelList.Count; i++) { ColorEdit colorEditY = this.Controls.Find("colorEdit" + i, true)[0] as ColorEdit; curveModelList[i].Color = colorEditY.Text; } this.DialogResult = System.Windows.Forms.DialogResult.OK; }
再將設定的顏色屬性賦值給當前設定顏色面板作用域的list
List<CurveModel> curveModelList = new List<CurveModel>();此時表單回傳OK，再回到右鍵打開視窗的地方
if (result == DialogResult.OK) { TriggerSetCurveColor(); XtraMessageBox.Show("設定曲線顏色成功"); }
此時會觸發設定曲線顏色的方法
public static void TriggerSetCurveColor() { if (OnSetCurveColor != null) { OnSetCurveColor(null, System.EventArgs.Empty); } }
此事件宣告
public static event EventHandler OnSetCurveColor;
事件會在圖形所在的頁面進行訂閱
ChartCompareHelper.OnSetCurveColor + = ChartCompareHelper_OnSetCurveColor;
訂閱執行的方法
private void ChartCompareHelper_OnSetCurveColor(object sender, EventArgs e) { ChartCompareHelper.SetCurveColor(this.zedGraphControl1); }
此方法傳遞當前ZedGraph物件
public static void SetCurveColor(ZedGraphControl zedGraphControl) { for (int i = 0; i < curveModelList.Count;i++) { zedGraphControl.GraphPane.CurveList[i].Color = System.Drawing.ColorTranslator.FromHtml(curveModelList[i].Color); } zedGraphControl.GraphPane.AxisChange(); zedGraphControl.Refresh(); zedGraphControl.Invalidate(); }
然后按順序設定曲線顏色，
