Dear Statalisters, Kieran says: Is there "an easy way to ensure that the LENGTH of the x-axis is the same in all FOUR graphs". As Kieran, Nick, and I find, it seems there is some fiddling to do to get what one is aiming for. Some method of command to control events (if possible) rather than fiddling around would be helpful, especially when several graphs are combined. Here I show FOUR graphs as a 2row x 2col combination, but have done 4row x 4col combinations and had to fiddle extensively. Including Nick's clever suggestion is helpful with some settings, but not necessarily with others. With other backgrounds/schemes the approach may not be ok as color of the ytitle may be seen through the background, as in example that follows, and presumably would not work at all when the graph is edited to be transparent - say in PowerPoint: sysuse auto, clear gen mpgX2= 2* mpg gen priceX1p5=1.5*price gr twoway scatter mpg price, ytitle("Hello" "world 1") xtitle("") name(one) graphregion(color(white)) ysize(2) xsize(2) gr twoway scatter mpgX2 priceX1p5, ytitle("", color("scheme background")) xtitle("") name(two) graphregion(color(white)) ysize(2) xsize(2) gr twoway scatter mpg price, ytitle("Hello" "world 3") name(three) graphregion(color(white)) ysize(2) xsize(2) gr twoway scatter mpg price, ytitle("", color("scheme background")) name(four) graphregion(color(white)) ysize(2) xsize(2) gr combine one two three four, row(2) ysize(2) xsize(2) ycommon xcommon graphregion(color(white)) When the ytitles in the offending graphs are removed then the x-axis lengths differ, as in the next example: sysuse auto, clear gen mpgX2= 2* mpg gen priceX1p5=1.5*price gr twoway scatter mpg price, ytitle("Hello" "world 1") xtitle("") name(one) graphregion(color(white)) ysize(2) xsize(2) gr twoway scatter mpgX2 priceX1p5, ytitle("", color("scheme background")) xtitle("") name(two) graphregion(color(white)) ysize(2) xsize(2) gr twoway scatter mpg price, ytitle("Hello" "world 3") name(three) graphregion(color(white)) ysize(2) xsize(2) gr twoway scatter mpg price, ytitle("", color("scheme background")) name(four) graphregion(color(white)) ysize(2) xsize(2) gr combine one two three four, row(2) ysize(2) xsize(2) ycommon xcommon graphregion(color(white)) I modifies the data so that it is not identical in each graph, which is more usually the case and this difference in data can affect the presentation. Maybe this problem is one for the developers at some point? Thans to all, Geoff.

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. -Nick On 10/23/2009 4:59 AM, G Livesey wrote: > Dear Statalisters, > > Kieran's question is a good one.
