A continuous
legend consists of a color ramp and a numeric scale indicating color
values.
In the
following figure, the continuous legend references a contour plot
with a fixed number of levels. The color ramp and legend values automatically
reflect these discrete levels. The legend options
VALUECOUNT= and
VALUECOUNTHINT= have no effect.
In this
next figure, the continuous legend references a contour plot with
a continuous gradient. The number of legend values displayed is automatically
determined by the legend, or decided by the contributing plot, such
as the CONTOURPLOTPARM with CONTOURTYPE=FILL. For plots with a continuous
gradient, you can use the legend options
VALUECOUNT= or
VALUECOUNTHINT= to control how many legend values
appear (these options are ignored if there is no gradient).
Within
an overlay-type layout, when a continuous legend is placed inside
the plot area with
LOCATION=INSIDE,
-
It is always placed on top of plot
lines and markers.
-
By default, its background is fully
transparent (
OPAQUE=FALSE), meaning that underlying lines,
markers, and data labels show through the legend.
-
Within
an overlay-type layout, when a continuous legend is placed outside
the plot area with LOCATION=OUTSIDE,
-
By default, its background is fully
opaque (OPAQUE=TRUE).
-
Its position can be controlled
with the HALIGN= and VALIGN= options.
