If no values are specified, then lines are drawn according to the tick locations selected by the SET SCALE command. Primary contour lines are determined by the long tick locations, and the secondary lines by the short ticks.
If the scale of the Z axis is set to be logarithmic, then the primary
lines are at powers of 10.
COLOR
Sets the color of primary contour lines.
CYCLE
CYCLE causes the line texture, color, and width attributes to vary from
one set of secondary contour lines to the next. The order of cycling
is set by the SET CYCLE command. The attributes specified by the SET
SECONDARY command override those specified by the SET CYCLE command.
Primary contour lines also vary according to cycles. If you specify
any attributes they are used for the primary contours, and override the
the cycles.
EXPAND
Sets the limits so that the selected data expands to fill the window.
This has no effect unless POINTS, or SETS are specified or the limits
on MESH data have been set by a SET LIMITS command.
See:SET MODE
FROM|TO|BY|N
You may also specify a range of contours with FROM,TO,BY,N. You may
specify any 3. The maximum number of contours you may specify at once
is 100.
example
TD:CONTOUR FROM 1 TO 10 BY 2
or...
TD:CONTOUR FROM 1 BY 2 N=5
or..
TD:CONTOUR 1,3,5,7,9
Draws contour lines at 1,3,5,7, and 9.
INTENSITY
Sets the line width or intensity of primary contour lines.
LABEL
If LABEL=ON is specified then any contours after the LABEL option will
be labelled. If no contours are specified LABEL=OFF produces the
default contours without any labels.
OUTSIDE
This turns on labels along the outside boundary of the contour plot for
all contours that terminate at the boundary. (Default)
INSIDE
This turns on labels in the interior of the contour plot for all
contours. (Default)
DOUBLE
This turns on double labels on the outside boundary of the contour plot
for all contours that terminate at the boundary. This labels both ends
of each terminal contour.
(Default:DOUBLE=OFF)
PARALLEL
Produces label which are parallel to inside contour lines. Normally
labels are horizontal parallel to the X axis.
(Default:PARALLEL=OFF)
PERPENDICULAR
Produces label which are perpendicular to inside contour lines.
Normally labels are horizontal parallel to the X axis.
(Default:PERPENDICULAR=OFF)
PRIMARY|SECONDARY
Sets the type of contour line. Primary lines use the default or
selected color, intensity, and texture. The secondary contour lines
are determined by the SET SECONDARY command. The default for secondary
lines is DOTTED.
SAVE
This saves the contour as a series of data sets rather than plotting
it. The new data sets have the name 'Contour ...' where ... is the
old data set name. You may select the new data set with the NAME='...'
option.
SIZE
SIZE=n determines the size of the contour labels in tenths of inches.
If unspecified the size is determined by the SET LABEL command. The
color, and intensity of the contour labels is also determined by the
SET LABEL command.
SOLID...
Sets the texture of primary contour lines.
example
TD:CONTOUR
Draws a series of contour lines according to the Z scale.
TD:CONTOUR SECONDARY 1,2,3,4,6,7,8,9,PRIMARY,20,LABEL,5,10 or...
TD:CONTOUR SECONDARY FROM 1 TO 9 BY 1 PRIMARY,20,LABEL,5,10 Draws contours for Z=1 to 20. Contour 5 and 10 are labeled. Contours 5,10, and 20 will be SOLID, all others are dotted. TD:CONTOUR SAVE 10 Saves the contours for Z=10 as separate data sets. No plot is produced.
