## 实现 ##

首先在ZedGraph的右键菜单中添加设置曲线颜色选项，在面板初始化的方法中订阅右键事件。

zgc.ContextMenuBuilder -= zgc_ContextMenuBuilder;     //上下文菜单生成事件订阅
    zgc.ContextMenuBuilder += zgc_ContextMenuBuilder;     //上下文菜单生成事件订阅

然后在订阅的方法中

private static void zgc_ContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip, Point mousePt, ZedGraphControl.ContextMenuObjectState objState)
            {
                #region 扩展上下文菜单
    
                #region 图形选项菜单
    
                ToolStripMenuItem mnuChartOption = new ToolStripMenuItem();     //新建菜单项对象
                mnuChartOption.Name = "set_curve_color";
                mnuChartOption.Text = "设置曲线颜色";
                //点击弹出图形选项对话框
                mnuChartOption.Click += delegate(object sender, EventArgs e)
                {
                    if (curveModelList == null || curveModelList.Count == 0)
                    {
                        XtraMessageBox.Show("当前没有曲线");
                    }
                    else
                    {
                        FrmSetCurveColor setCurveColor = new FrmSetCurveColor();
                        DialogResult result = setCurveColor.ShowDialog();                               //显示Dialog
                        if (result == DialogResult.OK)
                        {
                            TriggerSetCurveColor();
                            XtraMessageBox.Show("设置曲线颜色成功");
                        }
                    }
                };
                menuStrip.Items.Add(mnuChartOption);        //把图形选项对话框添加到上下文菜单中
    
                 #endregion
    
    
    
                 #endregion
    
    
    
                #region 汉化上下文菜单中的菜单项
    
                foreach (ToolStripMenuItem item in menuStrip.Items)
                {
                    switch (item.Name)
                    {
                        case "copied_to_clip":
                            item.Text = @"复制到剪贴板";
                            break;
                        case "copy":
                            item.Text = @"复制";
                            break;
                        case "page_setup":
                            item.Text = @"页面设置...";
                            break;
                        case "print":
                            item.Text = @"打印...";
                            break;
                        case "save_as":
                            item.Text = @"另存图表...";
                            break;
                        case "set_default":
                            item.Text = @"恢复默认大小";
                            break;
                        case "show_val":
                            item.Text = @"显示节点数值";
                            break;
                        case "title_def":
                            item.Text = @"标题";
                            break;
                        case "undo_all":
                            item.Text = @"还原所有缩放";
                            break;
                        case "unpan":
                            item.Text = @"还原上一步缩放";
                            break;
                        case "unzoom":
                            item.Text = @"还原缩放";
                            break;
                        case "set_curve_color":
                            item.Text = @"设置曲线颜色";
                            break;
                    }
    
                 }
    
                #endregion
    
             }

此时会汉化右键菜单并添加右键选项，并且其点击事件是打开设置曲线颜色面板。

在设置曲线颜色面板的代码中，在其load方法中调用初始化面板的方法，

此时要根据传递的曲线的Model的list去生成当前已有曲线的设置的panel。

那么当前已经有多少个曲线是如何传递的？

在前面ZedGraph生成曲线的地方所在的工具类中声明一个全局的list

public static List<CurveModel> curveModelList= new List<CurveModel>();

其中CurveModel是自定义的存取曲线属性的Model类

public class CurveModel
        {
            /// <summary>
            /// 曲线序号
            /// </summary>
            private int curveIndex;
    
            public int CurveIndex
            {
                get { return curveIndex; }
                set { curveIndex = value; }
    
            }
    
            /// <summary>
            /// 源文件
            /// </summary>
            private string originFile;
    
            public string OriginFile
            {
                get { return originFile; }
                set { originFile = value; }
    
             }
    
            /// <summary>
            /// 源文件完整路径
            /// </summary>
            private string originFileFullPath;
    
            public string OriginFileFullPath
            {
                get { return originFileFullPath; }
                set { originFileFullPath = value; }
    
             }
    
            /// <summary>
            /// 属性名
            /// </summary>
            private string attributeName;
    
            public string AttributeName
            {
                get { return attributeName; }
                set { attributeName = value; }
    
             }
    
            /// <summary>
            /// 颜色
            /// </summary>
            private string color;
           
            public string Color
            {
                get { return color; }
                set { color = value; }
            }
    
         }

声明完list后，其中生成曲线的地方也在这个工具类中

curveModelList.Clear();
    
     int curveIndex = 0;
                    for (int k = 0; k < compTestDataList.Count; k++)
                    {
                        //循环添加曲线
                        for (int i = 0; i < yList.Count; i++)
                        {
                            SymbolType symbolType = GetCurveSimple(yList[i].CurveType);                                //根据配置文件中曲线符号类型返回曲线符号标识
                            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);                         //根据配置文件设置曲线类型
                            myCurve.YAxisIndex = i;                                                                 //很关键，对应使用那个坐标值
                            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++;
                        }
                    }
    
    这样在生成曲线

时就将当前图形的所有曲线的属性存到一个工具类中全局的一个list中，然后在设置曲线颜色面板中获取这个list。

private void FrmSetCurveColor_Load(object sender, EventArgs e)
           {
                 curveModelList.Clear();
                 curveModelList = ChartCompareHelper.curveModelList;
                 initSetCurveColorPane(curveModelList);
    
            }

然后在使用这个list去初始化设置颜色的面板

private void initSetCurveColorPane(List<CurveModel> curveModelList)
            {
                int panelControlHeight = 20;
                int panelControlWidth = 50;
                foreach(CurveModel curve in curveModelList)
                {
                    PanelControl panelControl = new PanelControl();
                    #region 生成一个Label标识X轴
                    //生成一个Label标识X轴
                    LabelControl label = new LabelControl();
                    label.Text = "第" + (curve.CurveIndex + 1).ToString() + "条曲线（" + curve.OriginFile + "的" + curve.AttributeName + "）的颜色为：";
                    label.Location = new Point(Global.NOGROUP_HORIZONTAL_DISTANCE, Global.GROUP_VERTICAL_DISTANCE);
                    label.Parent = panelControl;
                    #endregion
    
    
                    #region 生成一个颜色选择器
    
                    //添加颜色选择器
                    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 设置X轴Panel的位置以及属性
    
                   
                    //设置panel的宽度
                    panelControl.Width = label.Width + colorEditX.Width + Global.NOGROUP_HORIZONTAL_DISTANCE * 3;
                    //设置panel的高度
                    panelControl.Height = label.Height + Global.GROUP_VERTICAL_DISTANCE * 2;
                    panelControlHeight = panelControl.Height;
                    panelControlWidth = panelControl.Width;
                    //设置panel的位置
                    panelControl.Location = new Point(Global.NOGROUP_HORIZONTAL_DISTANCE, (panelControl.Height * curve.CurveIndex) + (Global.GROUP_VERTICAL_DISTANCE *(curve.CurveIndex + 1)));
                    //设置Name
                    panelControl.Name = "panelControl" + curve.CurveIndex;
                    //将panel添加到当前窗体
                    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;
            }

然后设置颜色后，点击保存后在确定按钮的点击事件中

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;
            }

再将设置的颜色属性赋值给当前设置颜色面板作用域的list

List<CurveModel> curveModelList = new List<CurveModel>();

此时窗体返回OK，再回到右键打开窗口的地方

if (result == DialogResult.OK)
                        {
                            TriggerSetCurveColor();
                            XtraMessageBox.Show("设置曲线颜色成功");
                        }

此时会触发设置曲线颜色的方法

public static void TriggerSetCurveColor()
            {
                if (OnSetCurveColor != null)
                {
                    OnSetCurveColor(null, System.EventArgs.Empty);
                }
    
             }

此事件声明

public static event EventHandler OnSetCurveColor;

事件会在图形所在的页面进行订阅

ChartCompareHelper.OnSetCurveColor + = ChartCompareHelper_OnSetCurveColor;

订阅执行的方法

private void ChartCompareHelper_OnSetCurveColor(object sender, EventArgs e)
            {
                ChartCompareHelper.SetCurveColor(this.zedGraphControl1);
    
            }

此方法传递当前ZedGraph对象

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();
    
         }

然后按顺序设置曲线颜色。
