public class XYChart
extends Chart

Chart designed primarily to display data traces using DataSet interfaces which are more flexible and efficient than the observable lists used by XYChart. Brief history: original design inspired by Oracle, extended by CERN (i.e. plugin concept/zoomer), modified to mitigate JavaFX performance issues and extended renderer concept/canvas-concept/interfaces/+more plugins by GSI. Refactored and re-write in 2018 to make it compatible with Apache 2.0 which -- in the spirit of 'Ship of Theseus' -- makes it de-facto a new development. Contributions, bug-fixes, and modifications are welcome. Hope you find this library useful and enjoy!
