Open flash chart的使用文章已经很多了，这我就不多说了，贴段OFC画多条曲线的代码供大家学习参考,有不尽的地方请谅解，如果有疑问可以给我留言，也可以直接联系我。
OFC代码 using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Services;using System.Collections;namespace OFCWeb{ /// < summary > /// $codebehindclassname$ 的摘要说明 /// </ summary > [ WebService(Namespace = "http://tempuri.org/") ] [ WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1) ] public class Tline : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = " text / plain"; OFC.OFC chart = new OFC.OFC(); List < int > avgbid = new List < int > (); List < string > avgbid_month = new List < string > (); IList < int > list_used = new List < int > (); OFC.Line line_avgbid = new OFC.Line(); chart.Bgcolor = "#FFFFFF"; if (false) { // line_avgbid. Text = "没有数据信息"; } else { for ( int i = 20 ; i < 30 ; i ++ ) { avgbid. Add (i); } for ( int i = 0 ; i < 10 ; i ++ ) { list_used. Add (i); } line_avgbid. Values = avgbid; line_avgbid.
