Combining Impulse response functions in one graph

[Arbnor Gashi]

For the propose of comparing monetary policy before and after financial crisis of 2008 I need to combing to IRF graphs in one like in the figures below.

I know how to run the IRF command and have just one IRF in graph, but combining is something that I haven't seen till now in the Stata or in Stata books.
Please let me know if you have any idea how to do that.

I'm not acquainted with IRF command. That said, combining graphs in Stata is usually an easy task.

You may just type

help graph combine

And check whether the examples are helpful to you.

[Arbnor Gashi]

Thanks Marcos. However, my question is how to combine two IRF in one and not how to combine two graphs. If you look more clearly in the the second graph, shaded area represents one IRF and dotted line another IRF, which are shown in the same graph.

[Marcos Almeida]

I see, sorry for the misunderstanding. Hopefully you’ll get a helpful reply, since, as I said, I’m not acquainted with IRF.

Hi Arbnor! Did you find the answer to your question? I'm interested in the same question you asked here.

[Rich Goldstein]

I'm a bit confused about the question - what is not covered the "ograph" and "cgraph" options that you want to have?

[Justin Niakamal]

You can probably get what you want by working with the irf file.

E.g.

clear all 

webuse lutkepohl2, clear

var dln_inc dln_consump, lags(1/4)
irf create myirf, step(12) set(my_results) replace 

use my_results.irf, clear 

sort impulse response step
gen catvar = "Impulse: " + impulse + ", Response: " + response

encode catvar, gen(id)
xtset id step

xtline oirf, overlay 
exit
