Chart控件的多种使用方法

花了近一周时间专门研究.net 3.5平台提供的Chart控件的使用方法，感觉该控件的功能很强大，做出的图表效果也很美观，使用方法也并不复杂。如今先讲下Chart控件的部署及一些基本使用方法。

一、安装Chart控件所需的一些组件：

以上组件在MS站点上均有下载

安装完后打开VS2008，在工具箱中右键选项，加入关于MSCHART组件的两个选项，工具箱中即出现Chart组件。

PS:可下载MSChart.rar，Chart控件的学习手冊，内容很全面，涵盖全部关于Chart的用法

二、基本使用方法：

1.构建一个最简单的图表

.cs代码

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Web.UI.DataVisualization.Charting;

public partial class ChartTest_1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Series series = new Series("Spline");
series.ChartType = SeriesChartType.Spline;
series.BorderWidth = 3;
series.ShadowOffset = 2;

series.Points.AddY(45);
series.Points.AddY(34);
series.Points.AddY(67);
series.Points.AddY(31);
series.Points.AddY(27);
series.Points.AddY(87);
series.Points.AddY(45);
series.Points.AddY(32);

chart1.Series.Add(series);
}
}

2.直接在.cs代码中构建图表

public partial class ChartTest_2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Chart Chart1 = new Chart();
Chart1.Width = 600;
Chart1.Height = 400;
Chart1.RenderType = RenderType.ImageTag;
//此属性决定MSChart生成的图形以何种方式送到client，有三种：
//ImageTag，图形在服务端保存为暂时文件，并将暂时文件的URL作为HTML中<IMG>标签的SRC属性值。而此暂时文件的URL规则及暂时文件怎样生成可由ImageLocation属性确定。
//BinaryStreaming，不在服务端生成图形文件，<IMG>标签的SRC属性值将指向还有一个负责生成图形的.aspx页面
//ImageMap，不显示实际的图形，仅创建图片热区（image map）。
//默认值是ImageTag，就是会在服务端生成暂时文件。
Chart1.ImageLocation = "..//..//TempImages//ChartPic_#SEQ(200,30)";
Chart1.Palette = ChartColorPalette.BrightPastel;
Title t = new Title("灰常好", Docking.Top, new System.Drawing.Font("Trebuchet MS", 14, System.Drawing.FontStyle.Bold), System.Drawing.Color.FromArgb(26, 59, 105));
Chart1.Titles.Add(t);
Chart1.ChartAreas.Add("Series 1");
Chart1.Series.Add("Series 1");
Chart1.Series.Add("Series 2");

Chart1.Series["Series 1"].Points.AddY(5);
Chart1.Series["Series 1"].Points.AddY(8);
Chart1.Series["Series 1"].Points.AddY(12);
Chart1.Series["Series 1"].Points.AddY(6);
Chart1.Series["Series 1"].Points.AddY(9);
Chart1.Series["Series 1"].Points.AddY(4);

Chart1.Series["Series 2"].Points.AddY(2);
Chart1.Series["Series 2"].Points.AddY(6);
Chart1.Series["Series 2"].Points.AddY(18);
Chart1.Series["Series 2"].Points.AddY(16);
Chart1.Series["Series 2"].Points.AddY(21);
Chart1.Series["Series 2"].Points.AddY(14);

Chart1.Series["Series 1"].ChartType = SeriesChartType.Bar;
Chart1.Series["Series 2"].ChartType = SeriesChartType.Bar;
//图表横向排列

Chart1.Series["Series 1"]["PointWidth"] = "0.6";
Chart1.Series["Series 2"]["PointWidth"] = "0.6";
//图表条柱粗细

Chart1.Series["Series 1"].IsValueShownAsLabel = true;
Chart1.Series["Series 2"].IsValueShownAsLabel = true;
//显示条柱代表数字

Chart1.Series["Series 1"]["BarLabelStyle"] = "Center";
Chart1.Series["Series 2"]["BarLabelStyle"] = "Center";
//数字显示在条柱中间

Chart1.ChartAreas["Series 1"].Area3DStyle.Enable3D = true;
//显示3D效果

Chart1.Series["Series 1"]["DrawingStyle"] = "Cylinder";
Chart1.Series["Series 2"]["DrawingStyle"] = "Cylinder";
//更改条柱形状

Chart1.ChartAreas["Series 1"].Area3DStyle.IsRightAngleAxes = true;
//更改图表视角

Chart1.ChartAreas["Series 1"].Area3DStyle.IsClustered = true;
//更改条柱长度

Chart1.ChartAreas["Series 1"].AxisX.LabelStyle.IsEndLabelVisible = false;
//去掉Y轴多余数字

Chart1.ChartAreas["Series 1"].Area3DStyle.Inclination = 80;
//控制条柱粗细

Chart1.BorderSkin.SkinStyle = BorderSkinStyle.Emboss;
Chart1.BorderlineColor = System.Drawing.Color.FromArgb(26, 59, 105);
Chart1.BorderlineDashStyle = ChartDashStyle.Solid;
Chart1.BorderlineWidth = 2;
Chart1.Legends.Add("Legend1");
Chart1.Page = this;
HtmlTextWriter writer = new HtmlTextWriter(Page.Response.Output);
Chart1.RenderControl(writer);

}
}
