. It permits you to generate and plot histograms from Root or ASCII files, specifying the value via an expression involving the NTuple variables and the usual C functions. It has four sliders that apply range cuts to an expression; sliding them updates the plot in real time. It can combine multiple NTuples in one histogram, and can display multiple histograms on a single canvas (Combo Plot). HistoRoot is an open-source program distributed for Linux, Mac OS X, and Windows; it can also be built from source.HistoRoot is a Root macro that presents the user with a GUI that permits:
- Opening of Root Files
- Opening of ASCII files arranged in columns (space, tab, or comma separated)
- Selection of one or more NTuples
- Generation of 1-D histograms from the selected NTuple(s)
- Generation of 2-D histograms from the selected NTuple(s)
- Generation of X-Y plots from the selected NTuple(s)
- Defining persistent variables in terms of expressions of Ntuple fields
- Values histogrammed or plotted are entered as C expressions of variables or NTuple fields
- Four sliders are available to impose cuts based on the values of expressions
- Histograms and plots can be combined onto a single canvas
- For NTuples generated by G4beamlineOld, a count of each type of particle is printed.
Note you must have Root installed and working to use HistoRoot.
HistoRoot 2.0 is now compiled, which makes it run ~100 times faster than 1.0 on large files (1.0 ran as an interpreted Root macro). Because of this, you must install a compatible version of Root. It will fall back to running the macro if the compiled version won't load. You need a compiler only if you want to compile and run it with a version of Root that is incompatible with the distributed version.
