Controlling vertical space between subplots

Hi list,

I have a figure of 3 rows by 2 col of plots. I have a need to use 2 line xlabels for each of the subplots. So I did something like:

xlabel("Label 1\nLine 2")

for each of the subplots.

However when I do that, the 2nd line is lost for the top 4 subplots because I don't have enough vertical spaces between them. I tried something like:

subplots_adjust(hspace=0.4)

but it didn't seem to have any effect (I also tried different values for hspace - no effect at all).

What am I doing wrong?

I also have too much white space on the left and right side of the page and I tried to reduce that using the subplots_adjust function but it didn't seem to be doing what I want. I am sure I am not understanding something about subplots_adjust.

Could some one please clarify it (or point me to the right direction)?

Thanks,
