If a two-dimensional dataset represents a single-valued function,
the Fill form () will fill the area underneath
the function's curve with a solid colour.
Parts of the surface which would only be partially covered
(because of rapid function variation within the width of a single pixel)
are represented using appropriate alpha-blending.
The filled area may alternatively be that above the curve
or (in some plot types) to its left or right.
One example of its use is to reconstruct the appearance of a histogram plot from a set of histogram bins. For X,Y data which is not single-valued, the result may not be very useful.
This form may be used in the Plane or Time plot windows.
