Display of overlapping outer lines using twoway scatter with weighted markers

[Catherine Tisch]

Hi all

I’m trying to create a twoway scatter plot with weighted markers and am finding it difficult to display the markers as I'd like with a fill colour and a white outside line. I made a version of the graph in Microsoft Excel (see attached) and what I like about this version is you can see all the individual bubbles (n=57) with the overlapping/intersecting sections visible. When I create the same graph in stata, you don’t get a clear idea of the number of bubbles as many of them are obscured. Below is the code I have written using Stata/IC 12.1, is there a way I can make the outer white lines overlap for all markers like the graph made in Excel?

twoway (scatter y x [fweight = z], msymbol(circle) mfcolor(gray) mlcolor(white))

Many thanks in advance
Catherine

Plot white hollow circles on top of the gray markers:

sysuse auto , clear
twoway (scatter mpg weight [fweight=mpg], msymbol(O) mcolor(gray) msize(*3)) ///
(scatter mpg weight [fweight=mpg], msymbol(Oh) mlcolor(white) msize(*3))

Great, thanks so much for your help!
