st: Modifying -irf graph- output

["Michael S. Hanson" <mshanson@mac.com>]

	I have been trying, without much luck, to modify the graphical  
output of -irf graph- (using Stata/SE 9.2, updated May 17th).  To  
illustrate, the following code will generate a basic 3 x 3 plot of  
the impulse responses from a very simple VAR model:

webuse lutkepohl
var linv linc lcon
irf set test
irf create test_irf, step(12)
irf graph irf, irf(test_irf)

	1. How does one add a title to the whole plot?  (Much like the  
legend and the note at the bottom of the plot?)  A command like -irf  
graph irf, irf(test_irf) title("Title")- or -irf graph irf, irf 
(test_irf) title("Title", span)- simply adds the title to each  
subplot individually.

	2. How does one change the text of and/or remove the legend and the  
note?  I attempted variations on -irf graph irf, irf(test_irf) legend 
(off)-, which have had no effect.

	3. How does one change/control the axis labels and titles?  In  
particular, I want to either change or delete the text that reads  
"step" by default beneath the final row of subplots.

	I have been successful in controlling some aspects of how the  
subplots display;  for example, I have been able to change the range  
along the x-axis with the command -irf graph irf, irf(test_irf) xlabel 
(0(4)12, grid)-.  But I don't see how to change attributes that apply  
to the graph as a whole.  I'm hoping that someone will be able to  
suggest a simpler solution than to create a similar IRF graph by  
scratch -- that is, save each subplot individually with the - 
individual- option, then use -graph combine- to re-assemble them with  
the desired labels, titles, etc.  (Although if anyone has working  
code examples of that approach, I'd appreciate the opportunity look  
at them.)  Thanks for any suggestions.

                                        -- Mike
