The Precision setting specifies the number
of significant digits after the decimal place that the legend can
hold. You may also choose to display the numbers in a Fixed or Scientific format.
The Value Ticks setting holds the number of intervals that you want shown by the legend.
Note: The Value Ticks setting is not applicable for a legend that relates to a contour plot.
The Color Mode setting specifies whether
to use a User Specified color or the Default color for
the title and interval labels.
When Color Mode is set to User Specified, the Color setting specifies a color for
the title and interval labels. You can click the color bar to browse
through predefined colors, or click the Color Selector 
icon and select a color from the Select
color dialog box.
The Text Rotation setting specifies a value in degrees to rotate the text at (in a counterclockwise direction from horizontal).
The Text Height setting specifies a value
corresponding to the text height of the legend relative to the viewer
size. You may enter a value between 0.005 and 0.1.
Note: When using a legend as the basis for quantitative analysis, you should ensure that lighting is turned off for any objects colored by a variable. This will give you exact matches between object colors and legend colors.
