Question

I am trying to find a chart and plotting api that can be used in GWT using java, not javascript. The only problem I am having is the ones I have found require an internet conne

Answer 1

Client-side GChart. All in your app - no loading visualizations from external servers.

Answer 2

This is another open source api for charts in GWT hosted on http://code.google.com/p/gwt-rcharts/ you may find it useful. 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/

Answer 3

I just finished a little presentation on that topic. In there, I'm taking a short and somewhat subjective look at:

• clientsidegchart
• gflot
• dojox.charting
• Ico (and other Raphael based libs)
• GXT charts
• Smart GWT HTML5 Charts
• FusionCharts
• amCharts JavaScript Charts
• Google Chart Tools API
• JFreeChart (and other server side libs)

Only the last two of them require an active internet connection.
