RE: st: Pie chart problem

["Nick Cox" <n.j.cox@durham.ac.uk>]

When I wrote my -pieplot-, now on SSC, I stumbled on a bug affecting -plabel(_all)- which is, I gather, known to StataCorp but considered to bite only rarely, so that it continues to languish on their to do list, being repeatedly leapfrogged by bugs that are more important or more interesting. (I paraphrase freely.) 

So, my guess is that this is what is biting Philip. 

Ae work-around is to spell out separate -plabel()- calls. 

-pieplot- is _not_ the answer to Philip's problem, as it is directed at a different part of -graph pie-'s functionality, but looking at its code may help automate a better solution.

Thanks Maarten - much appreciated but, alas, with no joy.

My next strategy is do do a series of 'vanilla' pie chart with no
options and then build it up to try to isolate the problem.

Will let you know how this pans out.

Again, thanks for your time - really valuable.

Asides the current trauma, I must say Michael Mitchell's 2nd ed VGSG
has been terrific - highly recommend for fellow travelers
