LINTYP

 Default value:  LINTYP = 1.0 

 LINTYP either controls the type of line to use when  drawing a
 data curve or it indicates the hatch pattern  to use for filling
 under a data curve.  If LINTYP is between 1 and 10, inclusive,
 then line type number  LINTYP is chosen. The length of the dashes
 in the dashed line types are constant and do not depend on the
 separation between data points. 

 If 101 <= LINTYP <= 110, then the hatch pattern LINTYP-100 is
 chosen. If 211 <= LINTYP <= 299, then the dot fill pattern LINTYP-200
 is chosen. The polygonal region defined by the (x,y) coordinate pairs,
 with the last point connected to the first, will be filled with the
 chosen hatch or dot pattern.

 The definition of any line type can be changed with the command
 SET LINE. The definition of any hatch pattern can be changed with
 the command SET HATCH.  The line types can be displayed with the
 DISPLAY LINES command, while the hatch patterns can be displayed 
 with the DISPLAY FILL command.

CHARA

 Default value:  CHARA = XAXISA 

 CHARA controls the angle of the plotting symbols that are drawn
 at the data points.  CHARA is the angle, in degrees, measured
 counterclockwise, between the x-axis and a plotting symbol. By
 default, CHARA is set as a percentage.  

 If CHARA is set as a percentage, for example,  SET %CHARA 0,
 then CHARA is set to  XAXISA.  The actual value that %CHARA has
 been set to will be ignored.  This allows the user to change the
 angle of the x-axis and keep the plotting symbol angle the same
 as the angle of the x-axis.                            

CHARSZ

 Default value:  %CHARSZ = 1.0 

 CHARSZ is the size of the plotting symbols  that are drawn at
 the data points. There are two forms:

 CHARSZ  -- is the size of the plotting 
            symbols in world units   
 %CHARSZ -- is the size, expressed as a percentage of
            the height of the GPLOT window,
            that is, CHARSZ =  %CHARSZ*(YUWIND-YLWIND)/100.

 CHARSZ will be the base size of the plotting symbols if the 
 optional array, PSIZE, is included in the call to GPLOT. The
 size of the plotting symbol drawn at the i_th data point will be
 PSIZE(i)*CHARSZ. 

HISTYP

 Default value:  HISTYP = 0.0 

 HISTYP controls whether a normal line graph or a  histogram is
 drawn. Histograms can have tails or no tails  and the profile
 can be along the x-axis or along the y-axis. 

 HISTYP = 0.0 - normal line graph, not a histogram
 HISTYP = 1.0 - histogram with no tails and profile along
                the x-axis.  Can control the width and 
                colour of each individual bar.
 HISTYP = 2.0 - histogram with tails to y=0 and profile
                along the x-axis.  Can control the filling 
                hatch pattern, width and colour of each 
                individual bar    
 HISTYP = 3.0 - histogram without tails and profile along
                the y-axis.  Can control the height and 
                colour of each individual bar.
 HISTYP = 4.0 - histogram with tails to x=0 and profile 
                along the y-axis.  Can control the filling 
                hatch pattern, height and colour of each 
                individual bar   

 No plotting symbol will be drawn at the data  points when HISTYP
 > 0.  The filling hatch  pattern, width and colour of each
 histogram bar can be controlled by using the optional arrays
 PCHAR, PSIZE and  PCOLR which are passed in the call to  GPLOT. 
 The interpretation of these optional arrays is dependent on the
 value of MASK.
