Hi, Tatami http://code.google.com/p/tatami/ project wraps the dojo framework in GWT... it's open source. Regards, Hasan...

Re: A native GWT chart library?
The Google Chart API delivers an image instead of Flash. It's a server- side, hosted, URL-based charting API. All input data is provided as URL query parameters and the Google server responds with a chart image. The charts are clean and the API is easy to use This does mean it isn't going to be interactive, as Flash is. http://code.google.com/intl/nl/apis/chart/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: A native GWT chart library?
Pierre, Maybe use Walter's vector library here: http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm#download Granted it is lower level - you'd probably have to build on it to make graph classes - there may be some already made for it.

Re: A native GWT chart library?
See the following page where I maintain a list of various charting libraries (many are client-side), amidst a bunch of other toolkits. You might want to do a Find for chart. http://code.google.com/p/macdadi/wiki/BenLinks I unfortunately can't use Google Visualization bc it's for an intranet website and users may not have access to google servers. Eastwood (see page above for link and longer description) is an open- source clone of the Google Chart API, which you can install on your own server. So it works for an intranet. Flash solutions aren't an option either :( Got potential iPhone users? I'm with you. I saw gchart but I need pie charts that are completely filled. Sounds like you want a client-side charting library that is already wrapped as a GWT module. There are a few such options (see page linked above). I've used the GWT version of jmaki charting, which was okay, but had some bugs with text rendering that made me switch to using Google Chart API instead. Other options include flot, gflot, plotkit, dojo. If you find one you like a lot, but that is not available as a GWT module, you could probably make it into one without too much trouble. Thanks for your help, Pierre Good luck, and please let us know what you find and decide!
