SUMMARY

Controls the labeling of contour lines with contour level values.

SYNTAX

ZLABELS  {ON|OFF}  {options}

where options are one or more of the following:

SPACING v1 {v2 {v3} }
SIZE v
ANGLE v
LIST c1 c2 ... cn

The LIST option must appear last in this command.

INPUT

ON: Turn labeling of contour lines on.

OFF: Turn labeling of contour lines off.

SPACING v1 {v2 {v3} }:

Set the minimum, optimum, and maximum spacing between adjacent labels (in viewport coordinates) to v1, v2, and v3 respectively. If the second or third values are omitted, the previous values are used.

SIZE v: Set the size (height) of the labels (in viewport coordinates) to v.

ANGLE v: Set the desired maximum text angle the labels (in degrees from horizontal) to v.

LIST c1 c2 . cn:

Set the list of contour labels to use. Each entry in this list is used for the corresponding contour level. If the number of contour levels is larger than the length of this list, the entire list is repeated.

cn: ON|OFF|INT|FLOATn|EXPn|text

ON: Place a label on corresponding contour line. Use Fortran's free format capabilities to format the label from the contour level value.

OFF: Do not place a label on corresponding contour line.

INT: Place an integer label on corresponding contour line.

FLOATn: Place a floating point label on corresponding contour line with n values to the right of the decimal point. If n is omitted, the previous value for n is used.

EXPn: Place an exponentially formatted label on corresponding contour line with n values to the right of the decimal point. If n is omitted, the previous value for n is used.

text: Use text to label the corresponding contour line.

ON:	Turn labeling of contour lines on.
OFF:	Turn labeling of contour lines off.
SPACING v1 {v2 {v3} }:
	Set the minimum, optimum, and maximum spacing between adjacent labels (in viewport coordinates) to v1, v2, and v3 respectively. If the second or third values are omitted, the previous values are used.
SIZE v:	Set the size (height) of the labels (in viewport coordinates) to v.
ANGLE v:	Set the desired maximum text angle the labels (in degrees from horizontal) to v.
LIST c1 c2 . cn:
	Set the list of contour labels to use. Each entry in this list is used for the corresponding contour level. If the number of contour levels is larger than the length of this list, the entire list is repeated.
cn:	ON\|OFF\|INT\|FLOATn\|EXPn\|text
ON:	Place a label on corresponding contour line. Use Fortran's free format capabilities to format the label from the contour level value.
OFF:	Do not place a label on corresponding contour line.
INT:	Place an integer label on corresponding contour line.
FLOATn:	Place a floating point label on corresponding contour line with n values to the right of the decimal point. If n is omitted, the previous value for n is used.
EXPn:	Place an exponentially formatted label on corresponding contour line with n values to the right of the decimal point. If n is omitted, the previous value for n is used.
text:	Use text to label the corresponding contour line.
