Answer 1

 Zgl.IsShowPointValues = true;
可以自动显示鼠标坐标点!至于自动缩放，我还不会！

Answer 2

  public void  zedshowN( ZedGraphControl zg,int n)
        {
       //zg.GraphPane.CurveList[n]
            try
            {
                zg.GraphPane.CurveList[n].IsVisible = true;
                //zg.ZoomOutAll(zg.GraphPane);
                zg.RestoreScale(zg.GraphPane);
                zg.AxisChange();
                zg.Refresh();
            }
            catch{}
        }

Answer 3

 private void zedGraphControl2_MouseMove(object sender, MouseEventArgs e)
        {
            PointF mousePt = new PointF(e.X, e.Y);
            GraphPane myPane = this.zedGraphControl2.GraphPane;
            string tooltip = string.Empty;            // Find the Chart rect that contains the current mouse location
            ZedGraphControl s = (ZedGraphControl)sender;
            GraphPane pane = s.MasterPane.FindChartRect(mousePt);            // If pane is non-null, we have a valid location.  Otherwise, the mouse is not
            // within any chart rect.
            if (pane != null)
            {
                double x, y;
                // Convert the mouse location to X, and Y scale values
                pane.ReverseTransform(mousePt, out x, out y);
                // 获取横纵坐标信息
                tooltip = "(坐标x:" + x.ToString("f6") + ",坐标y: " + y.ToString("f6") + ")";
            }
            // this.zedGraphControl1.GraphPane.Title.Text = tooltip;
            myPane.XAxis.Title.Text = tooltip;
            this.zedGraphControl2.Refresh();        }
