  selects text properties.  The font can be any of the strings  
  "courier", "times", "helvetica" (the default), "symbol", or  
  "schoolbook".  Append "B" for boldface and "I" for italic, so  
  "courierB" is boldface Courier, "timesI" is Times italic, and  
  "helveticaBI" is bold italic (oblique) Helvetica.  Your X server  
  should have the Adobe fonts (available free from the MIT X  
  distribution tapes) for all these fonts, preferably at both 75  
  and 100 dpi.  Occasionally, a PostScript printer will not be  
  equipped for some fonts; often New Century Schoolbook is missing.  
  The font keyword may also be an integer: 0 is Courier, 4 is Times,  
  8 is Helvetica, 12 is Symbol, 16 is New Century Schoolbook, and  
  you add 1 to get boldface and/or 2 to get italic (or oblique).  
  The height is the font size in points; 14.0 is the default.  
  X windows only has 8, 10, 12, 14, 18, and 24 point fonts, so  
  don't stray from these sizes if you want what you see on the  
  screen to be a reasonably close match to what will be printed.  
  By default, opaque=0 and text is transparent.  Set opaque=1 to  
  white-out a box before drawing the text.  The default orient  
  (orient=0) is left-to-right text; set orient=1 for text rotated 90  
  degrees so it reads upward, orient=2 for 180 degree rotation so  
  it is upside down, and orient=3 for 270 degree rotation so it  
  reads downward.  
  The default text justification, justify="NN" is normal is both  
  the horizontal and vertical directions.  Other possibilities  
  are "L", "C", or "R" for the first character, meaning left,  
  center, and right horizontal justification, and "T", "C", "H",  
  "A", or "B", meaning top, capline, half, baseline, and bottom  
  vertical justification.  The normal justification "NN" is equivalent  
  to "LA".  Common values are "LA", "CA", and "RA" for garden variety  
  left, center, and right justified text, with the y coordinate at the  
  baseline of the last line in the string presented to plt.  The  
  characters labeling the right axis of a plot are "RH", so that the  
  y value of the text will match the y value of the corresponding  
  tick.  Similarly, the characters labeling the bottom axis of a plot  
  are "CT".  The justify= may also be a number, horizontal+vertical,  
  where horizontal is 0 for "N", 1 for "L", 2 for "C", or 3 for "R",  
  and vertical is 0 for "N", 4 for "T", 8 for "C", 12 for "H",  
  16 for "A", or 20 for "B".
