Looking for recommendations on open-source Java instrument visualization components [closed]

Question

I am putting together an Java application that needs to display some basic lab instrument components. For example, I'd like to display: a strip chart, oscilloscope-style trace, and a panel meter (galvanometer needle). Rendering requirements are open (as long as the engine is free and generally available). Any suggestions?

Answer 1

Take a look at JFreeChart. We've implemented a couple of strip chart applications with it. Offhand I'm not sure about an oscilloscope type trace, you'd have to look into it. It does look like there is a meter-like capability.

Answer 2

I've never used this myself so I cannot say how good it is but I came across these tools some time ago. DART Visualization tools. They use an open source license. Maybe there is something in there to help you.
