I created a bar graph using pgfplot and option ybar. I would get a graph wider. I used width option



                             xlabel=packet loss,ylabel=energia,
                             legend pos = north west]
            \addplot [fill=red!50,draw=red!50!black]
                table [x=pep,y=1]
            \addplot [fill=blue!70, draw=blue!50!black]
                table [x=pep,y=20]
            \addplot [fill=violet!70, draw=violet!50!black]
                table [x=pep,y=50]
            \addplot [fill=orange!50, draw=orange!50!black]
                table [x=pep,y=100]


but the plot became bigger in height and width. Instead I would have only a wider graph

I don't remember how many times I've already asked you to make minimal working examples (MWE) showing the needed packages. – egreg Dec 24 '12 at 16:29
I don't understand in this case which is the reason I have to put package...the example is not exacutable because it calls file in my hard disk. I'm asking only if it exist a option to get wider plot – Mazzy Dec 24 '12 at 16:32
People expert in plots usually have data files available. But you're not helping them in making a complete example that one can play with, without the need to guess packages. – egreg Dec 24 '12 at 16:34
ok right...I will add needed packages – Mazzy Dec 24 '12 at 16:35
If you give a width option and leave the height option free, it will try to keep the aspect ratio constant. Otherwise x post scale would be suitable for you though I'm not sure if I understand your question correctly. – percusse Dec 24 '12 at 17:03
