Description

SHADOWPLOT Add a shadow to an existing surface plot

For some surface plots, it can be helpful to visualize the shadow (2D projection) of the surface. This can give a quick perspective on the data's variance.

SHADOWPLOT PLANE Adds a shadow plot on the PLANE boundary

PLANE can be:
x, y, or z: Plots on back/top wall of x, y or z
1 .. 6 : Plots on Nth wall, numbered as in AXIS:
[xmin xmax ymin ymax zmin zmax]

SHADOWPLOT(HAX,PLANE) Adds a shadow plot on the Nth wall on axes HAX
HS = SHADOWPLOT(...) Returns a handle to the shadow (a patch)

Examples:
     figure
     surf(peaks)
     shading interp
     shadowplot x % Back X Wall
     shadowplot y % Back Y Wall

MATLAB release

MATLAB 7.0.1 (R14SP1)

16 Jan 2006	John D'Errico	I liked the idea until I tried it out. Shadowplot is of limited use in its current form. It works very nicely on the output of peaks, so then I tried it on one of my own 3d plots. It fails on more general patch objects, able to work on only objects of type 'surface'.
30 Jan 2006	John D'Errico	Its former self is only a "shadow" of what it is now. Sorry. I had to say it. 8-)

Updates
26 Jan 2006	Including nice enhancements from John D'Errico to include patches, too (it used to support just surfaces).
12 Sep 2007	Now includes limited support for data inside of HGTRANSFORMS. Thanks to Patrick Barney for this enhancement.
