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.
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.
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.
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.
