Stand-alone charts in GWT

问题:

I've been trying to get pretty charts to work in GWT on our internal network.

Playing around with GWT-Ext's charts is nice, but it requires flash and is really messy to control (it seems buggy, in general).

I'd like to hear about something that works with the least amount of dependencies and it also must work without a connection to the web (so, Google' charts API isn't a solution).

Edit: Indeed, I would rather a library that is all client-side.

回答1:

I'm building a GWT chart library based on Flot: http://gflot.googlecode.com I hope you find it useful. Contact me if you have any questions.

回答2:

Googling for "GWT +sparklines" has gotten me to gchart, which seems like what I need.
From what I understand - it's all client side and requires nothing more than their JAR file.

回答3:

Google's charts actually come in two flavours, and one of them does not require interaction with Google's servers - so should satisfy your needs.

Google Image Charts is the API you are thinking of, which is an API on Google's servers that returns images.

Google Interactive Charts is a client side javascript API that renders entirely within the browser: Google Interactive Charts

Google provides a GWT wrapper for the interactive charts: GWT Visualization API

It's not all rainbows and unicorns and you can find chart libs out there that make nicer charts, but it's pretty solid, works on all major browsers and we've been using it successfully for quite a while.

http://code.google.com/p/ext-ux-ofcgxt/ is a nice option if you're using ext-gwt

回答5:

Do you want something that has a server side component or entirely client driven? The best ones I have seen are all flash, alas. I have done little tricks with JS and GWT before, but there is only sophisticated I will get before I go hunting for a library to do it for me.

回答6:

There is also "sparklines" - they are available in lots of flavours (very simple charts though).

回答7:

gchart looks seriously awesome. Go with it !

回答8:

If you're looking for client-side check out flotr which is based on prototype javascript library or flot which is based on jQuery. Both work well, though flot seems like its got a bigger backing.

回答9:

If you are willing to go with flash, XML/SWF is a wonderful tool

回答10:

+1 flot, requires jQuery though, so might not play well with GWT, I haven't used that.

回答11:

Another flash option, with a pre-built GWT integration - Open Flash Chart / ofcgwt.

回答12:

I think that gwt-chart is a better framework for you.

回答13:

well.. i've used yahoo ui chart library (which GWT-Ext uses internally). Pretty neat solution, in the beta stage though.

Let us know the conclusion you arrive at..

回答14:

There is one open source api for charts in GWT hosted on http://code.google.com/p/gwt-rcharts/ . The API works on SVG/VML specification. You may find it quite easy to implement and use. You may find the demo at http://gwt-rcharts.appspot.com/
