JFreeChart and Wicket : width and height please

[Ista Pouss <is...@gmail.com>]

Hi,

I'm beguining to use JFreeChart. My tutorial is "JFreeChart and wicket
example" (http://cwiki.apache.org/WICKET/jfreechart-and-wicket-example.html).

That's work fine, except two things.

First, I think modestly there is a very little error : the tutorial
says "JFreeChart chart = (JFreeChart)getModelObject();", but it's work
better with "JFreeChart chart = (JFreeChart) getDefaultModelObject();"
for me.

Second (the question), how it is possible to set the width and height
in the html img of the graph ?

The generated html is <img wicket:id="graphe"
src="?wicket:interface=:2:votes:resultats:graphe:1:IResourceListener::">,
and I should prefer <img wicket:id="graphe"
src="?wicket:interface=:2:votes:resultats:graphe:1:IResourceListener::"
width="something" height="someother">

Thanks.

I implemented something simple for JFreeChart in an Advanced Wicket
presentation I did:

http://svn.carmanconsulting.com/public/wicket-advanced/trunk/src/main/java/com/carmanconsulting/wicket/advanced/web/common/resource/ChartImageResource.java

It just allows you to show the chart as an image and it allows you to
specify the width/height.
