You can display histograms created by a C++ or FORTRAN program using the HBook class. For this, use the CFBook libraryhttp://www.desy.de/ chekanov/CFBook/. This package generate 2 static libraries : libcbook.a (to be linked with C++) or libfbook.a (to be linked with FORTRAN).
Then you can read histograms filled by the CFBook library as shown in the examples "hbook.py" (for 1D) or "hbook2D.py".
>>> from jhplot import * >>> hb = HBook() # create HBook instance >>> hb.read("cpp.xml") # read output file "cpp.xml" from the CFBook package >>> print hb.listH1D() # list all histograms >>> h1 = hb.getH1D(10) # get H1D histogram with ID=10 >>> c1.draw(h1) # draw it
