TAB - TAB #!EF #!N #!N Functional Details #!N #!N The
color bar generated by this module can be collected with the
rest of the objects in the scene (by using a Collect
module) and incorporated into an image. #!N #!I0 #!N #!N #!I0
#!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* colormap #!EF #!EF #!I50 #!N must be a
color map (e.g., the second output of AutoColor or the first
output of the Colormap Editor). The input can also be an
imported #!F-adobe-times-bold-r-normal--18* .cm #!EF file (see #!Limport,dxall871 h Import #!EL ), in which case
the color-map part of the color-opacity map is extracted and used.
(A color map has a 1-dimensional "positions" component, representing the data
values, and a 3-dimensional "data" component, representing the RGB color assigned
to each data value.) #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* position #!EF
#!EF #!I50 #!N is a 2-dimensional vector (or a 3-dimensional vector
whose #!F-adobe-times-medium-i-normal--18* z #!EF -component is ignored) indicating the position of
the color bar in the final image. In viewport-relative coordinates, [0
0] places the bar at the lower left, and [1 1]
at the upper right. These same coordinates determine the reference point
that is used to position the bar relative to its placement
in the image (e.g., for #!F-adobe-times-bold-r-normal--18* position #!EF = [0 0],
the lower left corner of the bar is placed in the
lower left corner of the image). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18*
shape #!EF #!EF #!I50 #!N is a 2-vector that specifies the
length and width of the color bar, in pixels. For both
horizontal and vertical orientations, the first element of the vector is
the length and the second is the width. #!N #!I0 #!N
#!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* horizontal #!EF #!EF #!I50 #!N determines whether the orientation
of the color bar is vertical (0) or horizontal (1). #!N
#!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* ticks #!EF #!EF #!I50 #!N specifies the
number of tick marks to be placed on the color bar
(the actual number will at least approximate the specification). The default
varies the number in accord with the size of the bar.
#!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* min #!EF #!F-adobe-times-medium-r-normal--18* and #!EF #!F-adobe-times-bold-r-normal--18*
max #!EF #!EF #!I50 #!N specify the limits of the color
bar. The values can be scalar. If #!F-adobe-times-bold-r-normal--18* min #!EF is
an object (a data field), the minimum and maximum data values
of that field are used to set the corresponding limits of
the bar. If #!F-adobe-times-bold-r-normal--18* min #!EF is scalar and #!F-adobe-times-bold-r-normal--18* max
#!EF is an object (a data field), the maximum is the
maximum data value of that field. When neither is specified, the
minimum and maximum used are those of #!F-adobe-times-bold-r-normal--18* colormap #!EF .
#!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* label #!EF #!EF #!I50 #!N specifies
a user-supplied label for the color bar. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* colors #!EF #!F-adobe-times-medium-r-normal--18* and #!EF #!EF #!F-adobe-times-bold-r-normal--18* annotation #!EF #!I50
#!N set the colors of certain components of the color bar.
#!N #!N #!F-adobe-times-bold-r-normal--18* colors #!EF can be a single color (RGB
vector or color-name string) or a list. The color-name string must
be one of the defined color names (see #!Lcolor,dxall792 h Color #!EL ). #!N
#!N #!F-adobe-times-bold-r-normal--18* annotation #!EF can be a single string or a
list of strings, chosen from the following: "all.," "frame," "labels," and
"ticks." #!N #!N If #!F-adobe-times-bold-r-normal--18* annotation #!EF is not specified or
is "all"-- #!F-adobe-times-medium-i-normal--18* and #!EF if #!F-adobe-times-bold-r-normal--18* colors #!EF is a
single string--then #!F-adobe-times-bold-r-normal--18* colors #!EF is used for all color-bar annotation.
Otherwise the number of colors must match the number of annotation
strings exactly. The default frame color is "clear." #!N #!I0 #!N
#!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* labelscale #!EF #!EF #!I50 #!N determines the size of
the axes and tick-mark labels. For example, #!F-adobe-times-bold-r-normal--18* labelscale #!EF =
2.0 will display the labels at double their default size. #!N
#!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* font #!EF #!EF #!I50 #!N specifies the
font used for axes and tick-mark labels. You can specify any
of the defined fonts supplied with Data Explorer. These include a
variable-width font ("variable," the default for axes labels) and a fixed-width
font ("fixed," the default for tick-marks labels). #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18*

#!F-adobe-times-bold-r-normal--18* ticklocations #!EF #!EF #!I50 #!N specifies the explicit location for

the tick locations specified by #!F-adobe-times-bold-r-normal--18* ticklocations #!EF . If #!F-adobe-times-bold-r-normal--18*
ticklabels #!EF is specified, and #!F-adobe-times-bold-r-normal--18* ticklocations #!EF is not specified,
then #!F-adobe-times-bold-r-normal--18* ticklocations #!EF defaults to the integers 0 to n-1
where n is the number of items in #!F-adobe-times-bold-r-normal--18* ticklabels #!EF

#!N 1. #!F-adobe-times-bold-r-normal--18* min #!EF and #!F-adobe-times-bold-r-normal--18* max #!EF , if
given, or the extent of the data if #!F-adobe-times-bold-r-normal--18* min #!EF
and #!F-adobe-times-bold-r-normal--18* max #!EF are not given, set the extent of
the color bar. #!N #!I30 #!N 2. If you are using
Render or Display to render an object which contains a color
bar, when you change the resolution of the camera the size
of the color bar in pixels will not change. Thus if
you want the color bar to take up the same proportion
of the image, use the ScaleScreen module to change the size
of the color bar. #!I0 #!N #!N #!N #!N Example Visual
