SharePoint 2007- ASP:Chart

In a recent project one of the requirements was to produce a chart from 

data held within a SharePoint list.  

To fulfil this requirement I used the asp:Chart control.  The following steps outline how to set this up:

Setup

Namespace:

<%@ Register Assembly="System.Web.DataVisualization,                       Version=3.5.0.0, Culture=neutral,                       PublicKeyToken=31bf3856ad364e35"              Namespace="System.Web.UI.DataVisualization.Charting"              TagPrefix="asp" %>

Control:

<asp:Chart ID="Chart1" runat="server" />

Web Config:

Add the following tag within the <pages><controls>

<add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

Add the following tag within <httpHandlers>

<add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />

Useful Methods

Set Point:

private void SetPoint(string Series, int pointX, int pointY)
{
Chart1.Series[Series].Points.AddXY(pointX, pointY);
}

Set Legend:

private void SetLegend(string Series, string LegendText) { Chart1.Series[Series].LegendText = LegendText; }
