Just to let you know that I have discovered the on-line help under

help scheme by scaling

which explains the way that symbols and line thicknesses contract when
the by-option is specified, and seems to imply a way to turn it off in a
user-defined scheme. However, I would still greatly appreciate answers
to my two main queries.

Best wishes

Roger

Subject: st: What is -relativesize- relative to?

Hello All. I have 2 queries about symbol sizes and line thicknesses in
Stata 9 graphs:

1. In -[G] relativesize-, it is stated that relative sizes are relative
to the minimum of the height and the width of the graph (or subgraph)
being drawn. In the terminology of -[G] region_options-, do the "height"
and "width" belong to the outer graph region, the inner graph region,
the outer plot region, the inner plot region, or some other region? (I
notice that the symbol sizes get smaller if I specify the -by()-
option.)

2. Is there any stable and/or formal definition of the alternative sizes
-vtiny- to -extrahuge- (mentioned in -[G] markersizestyle-) and -vvthin-
to -vvvthick- (mentioned in -g(linewidthstyle)-), in terms of the
-relativesize- scale or otherwise?

I ask because I would like to choose marker sizes and line thicknesses
more intelligently than by trial and error (which can be
time-consuming), possibly using schemes. I am using Stata 9.2 under
Windows/XP.

Thanks in advance

Roger
