c# chart缩放,局部放大

效果：

左键划选放大区域，右键恢复

        /// <summary>         /// 初始化，传入要进行初始化的chart         /// </summary>         /// <param name="chart1"></param>         public static void InitChart (System.Windows.Forms.DataVisualization.Charting.Chart chart1)         {             //开启缩放功能             chart1.ChartAreas[0].CursorX.Interval = 0;             chart1.ChartAreas[0].CursorX.IsUserEnabled = true;             chart1.ChartAreas[0].CursorX.IsUserSelectionEnabled = true;             chart1.MouseClick += new System.Windows.Forms.MouseEventHandler(chart_MouseClick);         }           //右键恢复缩放         static void chart_MouseClick(object sender, MouseEventArgs e)         {             Chart chart1 = sender as Chart;             //右键恢复事件             if (e.Button == MouseButtons.Right)             {                 chart1.ChartAreas[0].AxisX.ScaleView.ZoomReset(0);             }         }

放大

仅针对x轴（y轴同理）

chartArea1.CursorX.IsUserEnabled = true; chartArea1.CursorX.IsUserSelectionEnabled = true;

缩小

chart1.ChartAreas[0].AxisX.ScaleView.ZoomReset();

• ZoomReset(0); —— 撤销所有放大动作
• ZoomReset(1); —— 撤销上一次放大动作

设置滚动条宽度

chart1.ChartAreas[0].AxisX.ScrollBar.Size = 5;

以上所有方法也可以在chart属性里直接进行设置

获取选区坐标

Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMinimum);//当前显示范围最小坐标 Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMaximum);//当前显示范围最大坐标

c# chart表格

• series1属性中XAxisType属性值设置为：Primary
• series2属性中XAxisType属性值设置为：Secondary

添加series会导致图表预览不可用

设置间隔与小数点

网格刻度
