st: -metan-: apparent calculation error in the graphical output

[Michael McCulloch <mm@pinestreetfoundation.org>]

Dear Statalist members,
Using the data below (which can be run as one do-file),
when the -metan- command is run as written in this example,  
an incorrect value appears in the graph for the -counts- data in only *one* of the cells: control group total in study#4.
Instead of the value “40” which was input for the control group total in study # 4, the value “30” appears in the graph. All other -counts- data are reported correctly.

Metan version: 		(SJ9-2: sbe24_3)
Stata version: 		Stata/IC 11.1 for Mac (64-bit Intel), Born 16 Jun 2010.
Machine: 			MacBook Pro, 2.16 HGz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM memory
Operating system: 	OS X 10.6.4

I'd appreciate any insights into this perplexing result.
