Hi,
I am new to Tapestry. Using Tapestry 5.0.10 with my application. I need
to display a chart image on my application using dynamic data. I am
using JFreeChart for that. But, I couldn't get the way to display the
image on my page.
I have to display the image while rendering the page, not as an
ActionLink. Can anyone help with this?
Regards,
Yeeswar

RE: Displaying image on T5 page
Hi Sven,
This will only work when the mychart.jpg already exists at that
specified path. But, as per my requirement I have to generate the JPG
dynamically and show it on the page.
I got a reference at
http://wiki.apache.org/tapestry/Tapestry5HowToCreateASimpleGraphComponen
t
But, it doesn't help much with my requirement.
Thanks,
Yeeswar.

Re: Displaying image on T5 page
Hi Yeeswar, I recently had exactly the same requirement, and solved it in the same way referenced in the wiki page. So then I rewrote my solution as a DisplayChart component, which takes a chart as a parameter and handles the rest of the work for you. A few notes/comments, though: 1) In my case, the chart wasn't generated from parameters in the url, per se. So I initially had problems with the browser caching the chart image because even though the chart had changed, the url was the same. I solved that issue by generating an identifier key for the chart that ensures that different charts get different urls. 2) I create the byte array outside of the StreamResponse. That way I can set the content length (and any other properties I want) in prepareResponse 3) The Wiki article uses jpeg compression. PNG is better for charts, and just as easy to do with the JFreeChart API. If you're interested in my DisplayChart code, write me off list and I'll send it along.
