今天小編給大家分享一下c# chart縮放和局部放大問題怎么解決的相關知識點，內容詳細，邏輯清晰，相信大部分人都還太了解這方面的知識，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。
效果：
左鍵劃選放大區域，右鍵恢復
/// <summary>
/// 初始化，傳入要進行初始化的chart
/// </summary>
/// <param name="chart1"></param>
public static void InitChart (System.Windows.Forms.DataVisualization.Charting.Chart chart1)
{
//開啟縮放功能
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);
}
//右鍵恢復縮放
static void chart_MouseClick(object sender, MouseEventArgs e)
{
Chart chart1 = sender as Chart;
//右鍵恢復事件
if (e.Button == MouseButtons.Right)
{
chart1.ChartAreas[0].AxisX.ScaleView.ZoomReset(0);
}
}僅針對x軸（y軸同理）
chartArea1.CursorX.IsUserEnabled = true; chartArea1.CursorX.IsUserSelectionEnabled = true;
chart1.ChartAreas[0].AxisX.ScaleView.ZoomReset();
ZoomReset(0); —— 撤銷所有放大動作
ZoomReset(1); —— 撤銷上一次放大動作
設置滾動條寬度
chart1.ChartAreas[0].AxisX.ScrollBar.Size = 5;
以上所有方法也可以在chart屬性里直接進行設置
獲取選區坐標
Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMinimum);//當前顯示范圍最小坐標 Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMaximum);//當前顯示范圍最大坐標
series1屬性中XAxisType屬性值設置為：Primary
series2屬性中XAxisType屬性值設置為：Secondary
添加series會導致圖表預覽不可用
#region 表格參數設置
//ChartArea chartArea = chart1.ChartAreas[0];
//表格標題內容
Title title = new Title();
title.Font = new System.Drawing.Font("宋體", 12F);
title.Text = "壓機曲線波動分析";
chart1.Titles.Add(title);
//設置坐標軸標題
chart1.ChartAreas[0].AxisX.Title = "位 移 / mm ";
chart1.ChartAreas[0].AxisY.Title = "壓 力 / Kg ";
//X,Y軸的最大值最小值
chart1.ChartAreas[0].AxisX.Minimum = 0;
chart1.ChartAreas[0].AxisX.Maximum = 100;
chart1.ChartAreas[0].AxisY.Minimum = 0;
chart1.ChartAreas[0].AxisY.Maximum = 200;
// 設置X,Y的坐標間距
chart1.ChartAreas[0].AxisX.Interval = 1;
chart1.ChartAreas[0].AxisY.Interval = 5;
//設置坐標軸標題的字體
chart1.ChartAreas[0].AxisX.TitleFont = new System.Drawing.Font("宋體", 12F);
chart1.ChartAreas[0].AxisY.TitleFont = new System.Drawing.Font("宋體", 12F);
//設置坐標軸柵格是否可見

chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = false;
chart1.ChartAreas[0].AxisX.ScaleView.Size = 20;
