I'm trying to create
a .net charting control completely in the code behind and insert that chart at
a specific location on the web page.
Here is my html page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div id="chart"></div>
</form>
</body>
</html>
Here is the code behind:
using System;
using System.Drawing;
using System.Web.UI.DataVisualization.Charting;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//SET UP THE DATA TO PLOT
double[] yVal = { 80, 20 };
string[] xName = { "Pass", "Fail" };
//CREATE THE CHART
Chart Chart1 = new Chart();
//BIND THE DATA TO THE CHART
Chart1.Series.Add(new Series());
Chart1.Series[0].Points.DataBindXY(xName, yVal);
//SET THE CHART TYPE TO BE PIE
Chart1.Series[0].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Pie;
Chart1.Series[0]["PieLabelStyle"] = "Outside";
Chart1.Series[0]["PieStartAngle"] = "-90";
//SET THE COLOR PALETTE FOR THE CHART TO BE
A PRESET OF NONE
//DEFINE OUR OWN COLOR PALETTE FOR THE CHART
Chart1.Palette = System.Web.UI.DataVisualization.Charting.ChartColorPalette.None;
Chart1.PaletteCustomColors = new Color[] { Color.Blue, Color.Red };
//SET THE IMAGE OUTPUT TYPE TO BE JPEG
Chart1.ImageType = System.Web.UI.DataVisualization.Charting.ChartImageType.Jpeg;
//ADD
A PLACE HOLDER CHART AREA TO THE CHART
//SET THE CHART AREA TO BE 3D
Chart1.ChartAreas.Add(new ChartArea());
Chart1.ChartAreas[0].Area3DStyle.Enable3D = true;
//ADD
A PLACE HOLDER LEGEND TO THE CHART
//DISABLE THE LEGEND
Chart1.Legends.Add(new Legend());
Chart1.Legends[0].Enabled = false;
}
}
I want to render the charting control inside the div with id="chart"
Thanks for the help!
