Request 1 seems to ask for a command that incorporates the analysis with
drawing the graphic. It has always seemed to me a strength of Stata that
it distinguished the operations: eg, you did fit / predict / graph to draw
a scatterplot with regression line. Recent and current trends seem to be
reversing this policy, which is fine for those who need to do repeated
standard operations, but dangerous whenever *real* data are analysed.
Hence I would rather stick to and articulate the old policy, and point to
the portmanteau procedures as conveniences.
Hence request 3 should be interpreted as providing an option for hi-lo
lines, which in specific cases may be SEs or CIs. That also reminds the
user to *note in the caption* which they are.
