Hi all,

I have found (in the jdc) that it seems to be difficult to create a dynamic (data coming from db) Pie chart using JSP page. I did a beans that create basic Bar charts. Is there any way to do the same for a pie charts ? (without commercial solutions).
I'll prefer a Beans instead of a applet, but at least this solutions can be take.

Thanks a lot
STF

HiLearningSTF,
Here I am giving you sample code below:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Pie Bean</title>
</head>
<body>

<h2>Pie Chart Bean Example</h2>

<%@ page import="com.sas.graphics.chart.*" %>
<%@ include file="Sampledata.inc" %>
&ltjsp:useBean id="pie" class="com.sas.servlet.beans.graphics.html.Pie"
scope="session">
</jsp:useBean>
<%
// Set the model
pie.setModelInterface(dataModel);

pie.setTitle("Product Sales");

pie.setPieLabelType( com.sas.graphics.chart.PieLabelTypes.SECTOR_WEIGHT );

DiscreteColorLegendStyle discreteLegendStyle = pie.getSectorLegendStyle();
discreteLegendStyle.setColorScheme(com.sas.graphics.chart.ColorSchemeTypes.INDUSTRY );
discreteLegendStyle.setVisible( false );

PolarLegendStyle polarLegendStyle = pie.getWeightLegendStyle();
polarLegendStyle.setStartAngle( 180.0D );

// Output the Pie
pie.setHeight(300);
pie.setWidth(400);
pie.setRequest(request);
pie.write(out);

%>

</body>
</html>
I hope this will help you out.

The difference is that it is quite easy to create bar charts using tables in HTML if you are writing the system dynamically, but a pie chart has to be created as an image.

Take a look at some of the AWT demonstrations you downloaded with the JDK- I believe there are some relevant parts in those.

HI rao_indts ,

Thanks for your reply, your solutions is very interessant.
This enligth me, because now I know that this could be done thanks to a beans.

But where did you find the used beans ??
Is it one of yours (developped by yourself) or is it a package that you found somewhere (where ?) ?

Thanks

Hi,

Thanks for your reply too, your help is precious.
But, in fact, I already did the query and the statistical statment and both works fine.
I'm working on a subject which is create a intranet web site which should be able to show statistical data (by charts) coming from the Remedy (oracle) database

The only problem that i still have is to "build or find this beans that create pie charts".
I'm investigating in findding some ressources, hope i will succeed in my search.

Thanks
