Re: st: Fill patterns in stata8 hbar graph

["Michael Blasnik" <michael.blasnik@verizon.net>]

Edward Tufte has also written extensively on the problems with "chart junk" 
that includes diagonal lines, cross-hatching and other fill patterns within 
bars.  I find that gray scale works quite well with 4 or fewer levels to 
distinguish, but if you need more then you should probably think about using 
a different type of graphic to convey your data -- bar graphs are usually 
not very good ways to present complex information that requires multiple 
fill patterns.
