Indeed, I have struggled with this as well. The not-perfect solution I usually use is to force Stata to include the space that the titles *would* take up in each graph, so the x-axis ends up the same size in all of them. This can be done by setting the color of the title to "scheme background":
```

. gr twoway scatter mpg price, ytitle("Hello" "world") name(one)

```
. gr twoway scatter mpg price, ytitle("Hello" "world", color("scheme background")) name(two)
```
. gr combine one two

```
And then fiddle with the -imargin- option to -graph combine- to get them closer together if desired.

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
about a lot to get what I want.

Does a solution exist? Can one be created?

With much appreciation and many thanks,

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.
