This charting library ${project.artifactId}- is an extension
in the spirit of Oracle's XYChart and performance/time-proven JDataViewer charting functionalities.
Emphasis was put on plotting performance for both large number of data points and real-time displays,
as well as scientific accuracies leading to error bar/surface plots, and other scientific plotting
features (parameter measurements, fitting, multiple axes, zoom, ...).
