     frame advance the current graphics window.  The current picture  
     remains displayed in the associated X window until the next element  
     is actually plotted.

             font=     plotting keyword  
          or height=   plotting keyword  
          or opaque=   plotting keyword  
          or orient=   plotting keyword  
          or justify=  plotting keyword  
     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".
