Scale break

[JM Giard]

I have a dataset with 79 observations. I am using Stata 13.1
I used the

graph box AFP, over(pyap_dic) title(AFP and pYAP)

and I obtained this graph:

Graph.gph

There is a big gap between 1500 and 4200 so I would like to create a scale break before showing the two "outliers".
I did read http://www.stata.com/support/faqs/gr.../scale-breaks/. My understanding from that website is that although scale breaks are not recommended, they can still be created.

so I tried:

gen AFP_break = cond(AFP == 4000, 0, AFP)
label def AFP_break 0 "4000"
label val AFP_break AFP_break
label var AFP_break AFP
graph box AFP_break, over(pyap_dic) ylabel (0 3000 7000, valuelabel) title(AFP and pYAP) yline(4000)

And it gave me this:

Graph2.gph

Which is not what I want. I only want the scale to be shorten between 1500 and 4200.

Is it possible to do so?

Thank you,

JM Giard
