Hi,

I have a related question to the one I asked before. I want to draw a graph
using the following codes. My question is:
If I do not specify 'asyvar', I get a simple graph without the legend I
specified, but I get sales category numbers: 0,10,20,40,60,90 which I want
to have. If I specify 'asyvar', I get a color graph with the legend I
specified, but sales category numbers (0,10,20,40,60,90) disappear, which is
weird. How can I get both legend under the graph and sales category numbers
right below each bar? I don't need different colors. 

egen salecat=cut(sale), at(0 (10) 100) 
levelsof salecat, loc(temp)
foreach v of loc temp {
 count if salecat==`v'
}
graph bar (mean) ad, over(salecat) exclude0 yti(Ad) b1ti(Sale) asyvar legend
(label(1 "N=2") label(2 "N=2") label(3 "N=2") label(4 "N=2") label(5 "N=3")
label(6 "N=2") rows(2) pos(6) )

sale	ad
0.4	0.0
5.7	0.5
15.7	3.4
19.1	3.8
21.2	4.1
25.5	10.8
40.0	4.8
47.4	12.3
62.0	7.5
64.2	16.5
67.4	10.2
91.8	7.0
92.2	14.0

Thank you in advance.
Ray Hawkins.

Sorry about the confusion Ray.  Can you include the group sizes in a legend?
If so, you could do something like this to include the sample sizes in a
legend.

sysuse auto
egen pr2=cut(price), group(10)
levelsof pr2, loc(pr)
foreach v of loc pr {
	count if pr2==`v'
	loc gr`v' = r(N)
}
gr bar (mean) weight, over(pr2) asyvar legend(label(1 `"N = `gr0'"')
label(2 `"N = `gr1'"') label(3 `"N = `gr2'"') label(4 `"N = `gr3'"')
label(5 `"N = `gr4'"') label(6 `"N = `gr5'"') label(7 `"N = `gr6'"')
label(8 `"N = `gr7'"') label(9 `"N = `gr8'"') label(10 `"N = `gr9'"')
rows(3) pos(12) span)

HTH,
Billy
