How to interpret Impulse response functions graphs ?

[gaberec]

Hi everybody this is my first post,
I'm an italian student interested in understand how to read graphs providing by Impulse response functions relative to oil shocks on economic activity.

I have 6 graphs for my 6 countries under study, do you know where is possible to understand the way how to describe all graphs?
At the beginning the trend is negative, then fluctuate and finally result stationary for nearly all countries

thanks


I've to put graphs in order to be helped better?
