I'm looking for a nice tool or widged that can generate and display charts. If possible with tooltips at data points and dynamic, so the user can resize or zoom it.

In RCP applications we embed the AWT libary jFreeChart (www.jfree.org), which provides great functionality but unfortunately does not work in RAP.

The google widges from the RAP incubator page look promissing, but their demo does not run under RAP 2.0 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=405552).

Does the RAP community have any advices for me about what chart tools I could use?

Thanks!

I have worked with several chart libraries (including the Google widgets in the incubator). The best solution I have found is to use a Browser widget to display html output from a chart library. That could either be a JavaScript library (e.g., d3js), or a Java library (e.g., jFreeChart, I have used ChartDirector[1], or BIRT[2]). ChartDirector uses HTML image maps and/or JavaScript to add interactivity. See this stackoverlow question on using jFreeChart in a web application[3]. You could use a ServiceHandler or custom Servlet to send the chart image. One advantage of using a Browser-based solution is that if designed properly it will work in RCP as well. When I get some time, I'll try to write a short tutorial.

Hope that helps,

There is a massive entry in market in terms of graphical representation which is in addition to 3D charting with support of html5 chart [URL removed].

I bumped into the same problem just two months ago. JFreeChart is great, but the only way to make it work is on the server. That means you generate some snapshot image and send it the client. Which generates lot of traffic even if you want the most basic form of interactivity. Besides, it consumes too much server resources.

The way to go is to embed a Javascript charting library into a Browser widget. There are literary tens of such libraries. Two more notable examples are Highcharts and AMCharts.

Hi.

My colleague started a simple charting widget based on d3 for RAP:
