change the apperance of mesh surface

huhua — Mon, 02 Jun 2008 16:19:55 -0400

Hi all,

I have a 100x100 image which is real-valued in [0, 1].

I currently use "mesh" to plot a 3D picture of it.

Is there a way to change the appearance such that each Z-direction (the
height) is represented by a bar shooting up?

This is like the 3D bars in Excel...

Because most elements in my image are around zeros, and there are only very
few non-zero values. So I think representing them with 3D bars can be very
good...

Please teach me how to do that. Thank you!

Ummm, bar3() perhaps ?

How to make the plot even more fancy?

"Fancy" as in those little cocktail appetizers that are pieces of
bacon wrapped around an olive with a coloured toothpick through them?
Or "fancy" as in a wearing a string-tie and top-hat ?

Yaaaay, fancy!
