# If pgnuplot is in a subdirectory with spaces in its name, extra
# quoting is required for windows for it to launch gnuplot.
# Moreover, it is suggested to use a raw string to avoid having to
# quote backslashes in the filename. Example:
#
# gnuplot_command = r'"C:\Program Files\gp371w32\pgnuplot.exe"'

# special reason:
