## 实现 ##

添加如下代码

this.zedGraphControl1.ContextMenuBuilder += MyContextMenuBuilder;

方法中

private static void MyContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip,
                        Point mousePt, ZedGraphControl.ContextMenuObjectState objState)
            {
                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 = @"还原缩放/移动";
                            break;
    
                        case "unpan":
                            item.Text = @"还原移动";
                            break;
    
                        case "unzoom":
                            item.Text = @"还原缩放";
                            break;
    
                        case "x_title_def":
                            item.Text = @"X 轴";
                            break;
                        case "y_title_def":
                            item.Text = @"Y 轴";
                            break;
    
                    }
                }
            }
