 +In addition, this tool supports GRoot histograms and canvases (see [[https://github.com/gavalian/groot/wiki| GRoot poject]]). The syntax for histogram creation and plotting  is similar to the PyROOT commands, thus it is easier 
 +to use this package for PyROOT users. 
 +You can find the Java API of this package in [[https://atlaswww.hep.anl.gov/hepsim/hepsimjar/api/|here]]. 
 + 
 + 
 +The following histograms are available: 
 + 
 +  * [[https://atlaswww.hep.anl.gov/hepsim/hepsimjar/api/org/jlab/groot/data/H1F.html|H1F 1D histogram]] 
 +  * [[https://atlaswww.hep.anl.gov/hepsim/hepsimjar/api/org/jlab/groot/data/H1F.html|H2F 2D histogram]] 
 + 
 +They can be plotted on the [[https://atlaswww.hep.anl.gov/hepsim/hepsimjar/api/org/jlab/groot/graphics/EmbeddedCanvas.html|EmbeddedCanvas]].
