        | 
__init__ ( self,  persist=0 )
 Start a gnuplot process.        Create a GnuplotProcessobject.  This starts a gnuplot
        program and prepares to write commands to it.         Keyword arguments:
          persistthe -persistoption is not supported on the
                       Macintosh so this argument must be zero.

 Mac gnuplot apparently requires
