Re: st: Fill patterns in stata8 hbar graph
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

Pas possible. I think Stata takes the work of Tukey (1977) "Exploratory
Data Analysis", & William Cleveland's books, Visualizing Data (1993) &
"The Elements of Graphing Data" (1994), as state-of-the-art. You will not
find any fill patterns in Cleveland's books (at least that I can find).
With a good printer, the various greys should be distinguishable on a
graph. I would be interested in hearing what others have to say on this.
Neither menus nor manuals seem to describe how bar fill colors in a hbar
graph can be replaced with patterns (such as diagonal lines, small
squares, etc.) that are easy to distinguish from one another in a black
and white setting. Any suggestions out there?
Thanks a lot!
