st: weighted scatter / different label size

[Philipp Rehm <philipp.rehm@gmx.de>]

Dear all,

Stata 9.2, born 20 Jul 2007, Win XP.

I would like to produce a scatter plot in which the labels are 
"weighted", i.e. are proportional to the size of what they indicate.

Here is an example:

sysuse auto, clear
keep in 1/10
scatter mpg weight [w=price], ms(Oh) msize(large)

In this scatter plot, the hollow circles are weighted; their size is 
proportional to the variable price.

If I add labels, however, the hollow circles all have the same size, 
despite the applied weights:

scatter mpg weight [w=price], ms(Oh) msize(large) ///
	mlabel(make) mlabsize(small)

I could work around this by using a two-way graph:

twoway ///
	(scatter mpg weight [w=price], ms(Oh) msize(large)) ///
	(scatter mpg weight, ms(none) mlabel(make) mlabsize(small))

Ideally, however, I would like to have a scatter plot in which only the 
labels are scattered (which I manage to do), and in which their size is 
proportional to a weighting variable (which I don't manage to do).

Any ideas?

Thank you!
Philipp
