Echo2chart Development

Wed, 06/28/2006 - 07:29 — as6o

I've been adding functionality to the echo2chart classes. Mainly, I've added support for tooltips and for entity selection (via an event handler.) It was developed against jfreechart 1.0.1.

It has been tested against Firefox 1.5.0.4 and IE 6.0.2900 SP2 on Windows XP and Firefox 1.5.0.4 on OS X.

By default ChartDisplay works as it did before. You can call .setShowTooltips(true) to turn on tooltips and add EntityListeners to listen for entity selection events.

This is my first attempt at Echo2 component work so it is garanteed to be imperfect (partial updates probably aren't working correctly) but I hope it is welcomed progress.

The patch file is attached. Please share your thoughts and suggestions. My hope is that this is patched back into the sources.

You can get the Echo2Chart component and other components in the wiki area, here's a link. You'll need Subversion or CVS to get the components: http://wiki.nextapp.com/echowiki/ComponentLibraries

Maybe a firewall is blocking your connection? SVN checkout works without problems.

I've attached a current build of the jars.

Has anyone managed to get entity selection working? I applied the patch but whenever I click on a chart, I get the following javascript error:

Line: 1
Char: 1
Error: 'Echo2Chart' is undefined
Code: 0
URL about:blank

Can someone give me another link to download the echo2chart library and examples? I am not able to download it from the echo2 wiki page. Please this is urgent.
Thanks in advance.
