Looking for recommendations on open-source Java instrument visualization components?

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 .

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.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
