Plot Quality

CLASS is usually used for interactive look at spectra, hence its default values are all oriented towards fast plotting on screen. These defaults can be changed by command SET. If the value of a parameter is not controlled by CLASS, the command will be passed on to GreG for processing.

The following GreG presentation parameters are useful :

• SET BOX_LOCATION
  It can be set to LANDSCAPE, PORTRAIT, SQUARE or 4 numbers indicating the position of the box in the plot page (in centimeters).
• SET CHARACTER Size
  Control the size of characters in centimeters
• SET FONT Quality
  Select the character quality to be used, SIMPLEX or DUPLEX. The fonts are identical to the ones used by GreG , and the character handling is the same (in command DRAW TEXT).
• GREG SET PLOT ...
  Define the plot page size. This command is identical to command SET PLOT_PAGE in GreG (but in CLASS , SET PLOT is already used to indicate whether spectra are broken lines of histograms). Refer to the GreG\ manual for details.
• SET TICK Size
  Define the tick size in centimeters
