今天小編給大家分享一下c# chart縮放和局部放大問(wèn)題怎么解決的相關(guān)知識(shí)點(diǎn),內(nèi)容詳細(xì),邏輯清晰,相信大部分人都還太了解這方面的知識(shí),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(lái)了解一下吧。
效果:
左鍵劃選放大區(qū)域,右鍵恢復(fù)
/// <summary> /// 初始化,傳入要進(jìn)行初始化的chart /// </summary> /// <param name="chart1"></param> public static void InitChart (System.Windows.Forms.DataVisualization.Charting.Chart chart1) { //開(kāi)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(fù)縮放 static void chart_MouseClick(object sender, MouseEventArgs e) { Chart chart1 = sender as Chart; //右鍵恢復(fù)事件 if (e.Button == MouseButtons.Right) { chart1.ChartAreas[0].AxisX.ScaleView.ZoomReset(0); } }
僅針對(duì)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(dòng)作
ZoomReset(1);
—— 撤銷上一次放大動(dòng)作
設(shè)置滾動(dòng)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(jìn)行設(shè)置
獲取選區(qū)坐標(biāo)
Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMinimum);//當(dāng)前顯示范圍最小坐標(biāo) Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMaximum);//當(dāng)前顯示范圍最大坐標(biāo)
series1屬性中XAxisType屬性值設(shè)置為:Primary
series2屬性中XAxisType屬性值設(shè)置為:Secondary
添加series會(huì)導(dǎo)致圖表預(yù)覽不可用
