        private ZMenuItem _menuFreeLine;
        private ZMenuItem _menuHorizontal;
        private ZMenuItem _menuFibonatti;
さらに「InitializeComponent()」で各変数初期化を追加
            this._menuLineMode = new ZMenuItem();
            this._menuFreeLine = new ZMenuItem();
            this._menuHorizontal = new ZMenuItem();
            this._menuFibonatti = new ZMenuItem();
// _menuView　のメニューにこれを追加
「this._menuView.MenuItems.AddRange(」の中に　, this._menuLineMode を追加
追加した位置番号に以下を追加（以下は9[10番目]に追加した例)
   this._menuLineMode.Index = 9;
       this._menuLineMode.MenuItems.AddRange(new ZMenuItem[] {
       this._menuFreeLine, this._menuHorizontal, this._menuFibonatti});
            this._menuLineMode.Text = "Line Mode" ;
            this._menuLineMode.Name = "LineMode" ;
            this._menuFreeLine.Index = 0;
            this._menuFreeLine.Text = "Free Line" ;
            this._menuFreeLine.Name = "FreeLine" ;
            this._menuFreeLine.Checked = true ;
            this._menuFreeLine.Click += new System.EventHandler( this.OnMenu);
            this._menuFreeLine.CID = CID .ToggleFreeline;
            this._menuHorizontal.Index = 1;
            this._menuHorizontal.Text = "Horizontal Line" ;
            this._menuHorizontal.Name = "Horizontal" ;
            this._menuHorizontal.Click += new System.EventHandler( this.OnMenu);
            this._menuHorizontal.CID = CID .ToggleHorizontal;

             _freeLines.Add(fl);
      }
⑥ChartCanvas.cs
ローカル変数追加
      private FreeLine _horizontalLine;
      private FreeLine [] _fibonattiLine;

      {
          if (line.DrawMode == FreeLine .LineDrawMode.Hilight && e.Button == MouseButtons.Left)
          {
               _diffX = line.Destination.X - line.Pivot.X;
              _diffY = line.Destination.Y - line.Pivot.Y;
               _destX = line.Destination.X;
               _destY = line.Destination.Y;
               _pivotX = line.Pivot.X;

           }
      }
  　_currentFreeLine = new FreeLine (new Point(e.X, e.Y));
