NAME

       mcdisplay-matplotlib - mcstas Graphical display of simulations using Matplotlib

SYNOPSIS

       mcdisplay-matplotlib [-h] INSTR name=value...

DESCRIPTION

       The mcdisplay-matplotlib front-end is a graphical debugging tool.  It presents a schematic drawing of the
       instrument  definition,  showing  the  position of the components and the paths of the simulated neutrons
       through the instrument.  It is thus very useful for debugging a simulation, for example  to  spot  compo‐
       nents  in  the  wrong position or to find out where neutrons are getting lost.  To use the mcdisplay-mat‐
       plotlib front-end with a simulation, run it as follows: mcdisplay-matplotlib INSTR args... where INSTR is
       the name of either the instrument source INSTR.instr or the simulation program INSTR.out  generated  with
       mcstas,  and  args are the normal command line arguments for the simulation, as for mcrun.  The -h option
       will list valid options.

       The default plotting backend is mxdisplay-pyqtgraph, but there exists a  number  of  additional  plotters
       such  as  mxdisplay-matplotlib,  mxdisplay-webgl-classic  (using WebGL), mxdisplay-webgl (using WebGL and
       NodeJS), mxdisplay-matlab (using Matlab or Octave).  This is the Matplotlib plotting tool.

OPTIONS

       INSTR  Displays the given McCode 3D model with its defaults/current parameters.

       name1=value1 ...
              Displays the given McCode model with given parameters.

       -n N, –ncount N
              Number of particles to simulate
