st: combining many -twoway (histogram)- graphs

[Daniel M�ller <d.mueller@agr.uni-goettingen.de>]

Hi,

I would like to combine several histograms with:
-------------------
. use evaluation, clear
 
. forvalues i = 1(1)10 {
  2.         twoway (histogram q`i', discrete frequency), xlabel(1(1)5)
name(q`1', replace) scheme(sj)
  3. }

. graph combine q1-q10
q1-q10 is not a memory graph
invalid syntax
invalid syntax
r(198);
-------------------

I can only combine up to two graphs with -graph combine q1 q2-. From three
onwards, I receive the same error message as above.

Is there a workaround? Or another option to combine the multiple histograms?

Thanks!
