Hi list,

I'm having a problem with combining twoway pcarrow graphs, in Stata 12.1 for Windows. I am combining a lot of graphs (560, to be precise) into a large matrix of graphs, and naturally, the sizes of markers and text are accordingly shrunk by Stata. However, the arrowheads of my pcarrow graphs, which have the right sizes in the separate graphs, become way too large in the combined graph. 
The command I use is: 
graph combine `allgraphs', rows(14) ysize(5) xsize(20).  (the xsize and ysize options are used to regulate the aspect ratios of the subgraphs). 
I also tried 
graph combine `allgraphs', rows(14) ysize(5) xsize(20) iscale(*0.05),
but this only shrinks the sizes of the *other* markers and text (my subgraphs are actually scatterplots overlaid with pcarrow graphs), but does not affect the arrowheads. 

Any suggestions?

Best, Rense
