今天小编给大家分享一下c# chart缩放和局部放大问题怎么解决的相关知识点，内容详细，逻辑清晰，相信大部分人都还太了解这方面的知识，所以分享这篇文章给大家参考一下，希望大家阅读完这篇文章后有所收获，下面我们一起来了解一下吧。
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
