ASP.NET Chart如何生成蜡烛图

K线图（Candlestick Charts）又称蜡烛图、日本线、阴阳线、棒线、红黑线等，常用说法是“K线”。它是以每个分析周期的开盘价、最高价、最低价和收盘价绘制而成。后K线图因其细腻独到的标画方式而被引入到股市及期货市场。股市及期货市场中的K线图的画法包含四个数据，即开盘价、最高价、最低价、收盘价，所有的k线都是围绕这四个数据展开，反映大势的状况和价格信息。如果把每日的K线图放在一张纸上，就能得到日K线图，同样也可画出周K线图、月K线图。

工具/原料

方法/步骤

打g工vs开发工具，新建一个web项目，然后再新建一个文件。

然后打开工具栏，拖动Chart。

绘制如下图所示的页面。详细代码如下：<%@ Register Assembly='TeeChart' Namespace='Steema.TeeChart.Web' TagPrefix='tchart' %>

设置控控件属性。

增加后台相关代码

导入命名空间

增加控件处理方法

后台详细代码如下：using System;using System.Collections;using System.ComponentModel;using System.Data;using System.Drawing;using System.Web;using System.Web.SessionState;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.HtmlControls;using System.Web.UI.DataVisualization.Charting;using CMS.BLL;namespace CMS.Web.admin{ public partial class ProductK : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { PageRefresh('XAUUSD'); } } #region protected void btnAU_Click(object sender, EventArgs e) { PageRefresh('XAUUSD'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnAG_Click(object sender, EventArgs e) { PageRefresh('XAGUSD'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnPt_Click(object sender, EventArgs e) { PageRefresh('XPTUSD'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnPd_Click(object sender, EventArgs e) { PageRefresh('XPDUSD'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnCopper_Click(object sender, EventArgs e) { PageRefresh('Copper'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnUk_Click(object sender, EventArgs e) { PageRefresh('UKOil'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnEu_Click(object sender, EventArgs e) { PageRefresh('EURUSD'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnGb_Click(object sender, EventArgs e) { PageRefresh('GBPUSD'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnEur_Click(object sender, EventArgs e) { PageRefresh('EURGBP'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnUs_Click(object sender, EventArgs e) { PageRefresh('USDJPY'); ClientScript.RegisterStartupScript(GetType(), '', ''); } protected void btnUsd_Click(object sender, EventArgs e) { PageRefresh('USDCHF'); ClientScript.RegisterStartupScript(GetType(), '', ''); } #endregion private void PageRefresh(string type) { this.cPu.ViewStateContent = SerializationContents.All; this.cPu.EnableViewState = false; Series series = cPu.Series[0]; this.FillStockData(series, type); if (type == 'EURGBP' ||type == 'EURUSD' || type == 'USDCHF' || type == 'EURUSD') { this.cPu.ChartAreas[0].AxisY.LabelStyle.Format = 'F4'; } else if (type == 'GBPUSD') { this.cPu.ChartAreas[0].AxisY.LabelStyle.Format = 'F2'; } else if (type == 'USDJPY') { this.cPu.ChartAreas[0].AxisY.LabelStyle.Format = 'F3'; } else { this.cPu.ChartAreas[0].AxisY.LabelStyle.Format = 'F'; } this.cPu.ChartAreas[0].AxisX.LabelStyle.Format = 'MM-dd'; this.cPu.ChartAreas[0].AxisX.LabelStyle.IsEndLabelVisible = false; this.cPu.ChartAreas[0].AxisX.IsMarksNextToAxis = false; this.cPu.ChartAreas[0].AxisY.LabelStyle.IsEndLabelVisible = false; series.BorderWidth =1; series.ShadowOffset = 1; // series.BackSecondaryColor = Color.Red; series.Color = Color.Green; this.cPu.ChartAreas[0].AxisX.Interval = 3; cPu.ChartAreas[0].AxisX.LineWidth =1; } ///
