Twoway with data manipulation can be flexible
(and isn't always 2 ways)

o Hand drawn box and histogram plots use

o Parallel coordinates use

o Distribution illustrations do do-file

o Regression illustration do do-file

o Population pyramid do do-file

o twoway? use

Note: click on the use or do links to see the graphs,
click on the do-file links to see the graph commands.

The "box and histogram" was created by Nick Cox using his tabplot
program. The "parallel coordinates" plot was created with Nick Cox's
parplot program. The "twoway?" plot was created with Nick Cox's
triplot program. All three of Nick's programs are available from the
SSC archives. Just type findit triplot (or one of the other program
names) to locate the program. The remaining graphs are "simple" twoway
commands which can be seen by clicking do-file

With all of this flexibility and legitimate concerns, why open Pandora's box
and discuss the internals of graphics now?

First, I wanted to talk about something new and, as we can see, many are
already discovering the flexibility of twoway. In fact, they have
surprised me and taught me new tricks.

Second, we believe that things are stable enough that the things I am going to
show you will continue to work, even though they will remain undocumented.

Third, and most important, these facilities are cool; and I wanted to talk
about them before another developer beat me to the punch.

I do not expect everyone to immediately start developing new graphs with the
information from this talk. We will at best scratch the surface of just a few
aspects of the graphics facilities. I do expect a few people to surprise me by
using these facilities in unexpected ways. I also expect everyone will learn
a few useful tricks and gain a better understanding of the structure of Stata
graphics.

If all of this sounds beyond what you want to hear about graphics, I recommend
beginning with the following resources.
