| If you want to see a pop-up canvas with the output histogram on your screen, change the line "c1.visible(False)" to "c1.visible()" and comment out "sys.exit(0)" at the very end of the "ttbar_mg5.py" macro. You can change the output format from "SVG" to "PDF", "EPS" or "PNG". Look at the [[http://jwork.org/dmelt/api/doc.php/jhplot/package-summary | Java API]]. | If you want to see a pop-up canvas with the output histogram on your screen, change the line "c1.visible(False)" to "c1.visible()" and comment out "sys.exit(0)" at the very end of the "ttbar_mg5.py" macro.

| This example runs "higgsjet_gamgam_mcfm.py" code using online files and creates a Higgs differential cross section with PDF uncertainties. We use DMelt to do the calculations (after updating one jar file). You can also use ROOT/C++ to do the same. | This example runs "higgsjet_gamgam_mcfm.py" code using online files and creates a Higgs differential cross section with PDF uncertainties.
