获取ZedGraph横纵坐标值信息

private void zedGraphControl1_MouseMove(object sender, MouseEventArgs e) { // Save the mouse location PointF mousePt = new PointF(e.X, e.Y); string tooltip = string.Empty; // Find the Chart rect that contains the current mouse location GraphPane pane = ((ZedGraphControl)sender).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 = "(" + x.ToString("f2") + ", " + y.ToString("f2") + ")"; } toolTip1.SetToolTip(zedGraphControl1, tooltip); }
