Alternative output

The parameter pgdev allows the user to specify a pgplot device, but, in contrast to the pgplot standard, the file name should not be included, but instead supplied via the parameter plotfile. Some examples of values of pgdev and plotfile, and their interpretations:

• To display to an xserve device:

  pgdev=/xs
  

• To write a GIF file called myfile.gif:

  pgdev=/gif plotfile=myfile.gif
  

• To write a colour postscript file called op.ps:

  pgdev=/cps plotfile=op.ps
  

However note that at present, if a colour postscript device (pgdev = `/cps'), a fits file (pgdev = `/fits') or a ppm file (pgdev = `/ppm') are selected, the task in fact bypasses pgplot and writes the postscript file directly. This is because all the pgplot devices use at largest an 8-bit colour palette: this does not result in optimum plots. Writing the output files directly, on the other hand, allows one to use a much larger number of colours.
