 +It asks several questions and creates an icon on a desktop. It is recommended to install the program in "C:\Jas4pp" (for Wnindows) to avoid permission problems.

 +======  Histograms from Fortran and C++ ======
 +
 +Jas4pp can visualize histograms created by Fortran or C++ code (but without using ROOT). For this, use a light stand-alone library called CFBook (See [[https://datamelt.org/?id=cfbook-library|CFBook]]). You can compile it using gcc (for C++ programs) or gfortran (for Fortran program). This library creates XML file with 1D and 2D histograms, that can be read by Jas4pp. Here is an example of reading 1D histogram from fortran.xml file:
 +
 +<hidden Click to show the Python code>
 +<code python>
 +from jhplot  import *
 +from jhplot.io import *
 +
 +hb = CFBook()
 +hb.read("fortran.xml")
 +print hb.listAll()
 +print hb.getKeysH1D() # list keys
 +h1=hb.getH1D(1)        # use the key 1 to retrive H1D
 +c1=HPlot("Test")
 +c1.setGTitle("Histograms from a file");
 +c1.visible(1)
 +c1.setAutoRange()
 +c1.draw(h1)
 +
 +</code>

 +====== Reading LCIO files from Delphes ======
 +
 +The Delphes program has somewhat different containers, but they alos can be processed by Jas4pp using Python code. You can find Delphes LCIO files in [[https://atlaswww.hep.anl.gov/hepsim/info.php?item=368]] (created for Snowmass21). See rfast052 tag. To process such LCIO files, look at the example Python scripts in the directory "examples/delphes".
