```Dear Statalisters,

Kieran's question is a good one. Martine's answer may solve Kieran's current
problem, though only partially answers the question.

"ensure that the LENGTH of the x-axis is the same"

I have no easy solution  to do this and ask how to do this when the graphs
to combine do not have

A) a common x-axis or
B) perhaps (I did not try this) span different ranges of a common axis or
C) carry different axis-titles (e.g. some with and some without such
titles), which can affect the proportion of space given to the graph and
axis/margins and so length of the axis.

A more comprehensive solution than -common axis- would be welcome though I
have not found one myself, and like Kieran have in the past had to play
about a lot to get what I want.

Does a solution exist? Can one be created?

With much appreciation and many thanks,

Geoff. Livesey

You are not looking for the -xcommon- option to -graph combine-, are you?

set obs 10000

gen x1=  rnormal(10,100)
gen x2=  rnormal(100,10)

gen num=_n

tw (line x2 num),  /*

graph combine gr1 gr2, /*

Betreff: st: -graph combine- question

....

Suppose I have four graphs that I combine to look like this:

http://i37.tinypic.com/314wkfb.jpg

My question is: is there an easy way to ensure that the length of the x-axis
is the same in all four graphs when they are combined.

I can probably fiddle around with margin gaps until I get them right, but is
there something a little easier than that?

Thanks.
