Can someone tell me which .jar files to download to get the newest Jzy3d version? I have looked at their website but I don't know which files to download.
The easiest way is to use maven to build Jzy3d charts. Install maven if you don't have it.
Add a maven pom.xml file at the root of your project, similar to this one. Running the following command will import dependencies and build the project
mvn clean test install
If you want to retrieve jar manually (discouraged), you can get jzy3d builds here. You will also have to download jzy3d dependencies (jogl, jply, jmathio, jdt-core, miglayout, opencsv, etc) as listed in jzy3d-api pom file.
