Re: st: RE: Graphing limitations / questions

dear statalisters,

perhaps this is not an appropriate response to fredik's graphing problem but 
maybe i can say my piece too as a kind of christmas wish list for stata corp 
to consider in their future versions (or even as an update to 8.2). i often 
do meta-analysis using metan command in stata. what i would like to do 
however, once i have the forest plot, and the summary point (with its 
confidence intervals), is to put this summary point together with other 
summary points (from other meta-analysis) onto another forest plot so that 
visual comparison can be made.

for example, we want to graphically visualised the comparison of odds ratios 
from individual meta-analyses of thrombolytics, angioplasty and stenting. at 
the moment my approach is to do the meta-analysis in stata then use arcus to 
do the comparison plotting. i wish i can do this in stata with the various 
ancillary options made available too (e.g. dots, boxes, diamond for point 
estimate, different colors of graphs, backgrounds and lines - where stata 
excels).  however, at present, i don't think stata is able to do this and 
hence the wish list.

apology if this post seems off topic.

kind regards,
bw
