It has also support for H1D, P1D, F1D as well as for graphical primitives and Feynman diagrams; * SPlot a light-weight 2D canvas with a support for H1D, P1D, F1D as well as for the standard Java arrays * HPlot2D used for contour … text/html 2010-07-09T20:24:05-06:00 Sergei Chekanov http://jwork.org/jhepwork/wikidoc/doku.php?id=randomnumbers&rev=1278728645&do=diff The jHepWork random numbers can be constructed using several approaches: * The native Java API for random numbers.

All of this works together with the HPlot canvas. You cannot interact with the mouse using such labels. Interactive labels You can annotate your figure on the HPlot canvas putting interactive labels, so you can move them around with the mouse and edit.
