Blue-gray thin frame when combining graphs

[ulas alk]

Hi Everyone,

I want to combine two graphs using 'gr combine' command. Each individual graph looks as I want but when I combine them, there appears a blue-gray thin frame between and on the corners of the graphs. For illustration, you can find my sample code below.

sysuse auto.dta, clear
gen order = _n

twoway (line price order, ylabel(3000(3000)16000, nogrid labsize(medlarge)) ytitle("Price", size(medlarge)) xtitle("Order", size(medlarge)) xlabel(1(15)74, labsize(medlarge)) title("Figure 1") plotregion(fcolor(white)) graphregion(fcolor(white)) bgcolor(white) text(12000 43 "some text", size(medlarge)) ), saving("price", replace)

twoway (line price order, ylabel(3000(3000)16000, nogrid labsize(medlarge)) ytitle("Price2", size(medlarge)) xtitle("Order", size(medlarge)) xlabel(1(15)74, labsize(medlarge)) title("Figure 2") plotregion(fcolor(white)) graphregion(fcolor(white)) bgcolor(white) text(12000 43 "some text", size(medlarge)) ), saving("price2", replace)

gr combine "price.gph" "price2.gph", plotregion(fcolor(white)) graphregion(fcolor(white)) xsize(7.5) ysize(3.5) ycommon title("Combined")



Could you please help me to remove those lines? Thanks.

Best,
Ulas

You can add lcolor(white) in graphregion

sysuse auto.dta, clear
gen order = _n

set scheme s2color

twoway (line price order, ylabel(3000(3000)16000, nogrid labsize(medlarge)) ytitle("Price", size(medlarge)) xtitle("Order", size(medlarge)) xlabel(1(15)74, labsize(medlarge)) title("Figure 1") plotregion(fcolor(white)) graphregion(fcolor(white) lcolor(white)) bgcolor(white) text(12000 43 "some text", size(medlarge)) ), saving("price", replace)

twoway (line price order, ylabel(3000(3000)16000, nogrid labsize(medlarge)) ytitle("Price2", size(medlarge)) xtitle("Order", size(medlarge)) xlabel(1(15)74, labsize(medlarge)) title("Figure 2") plotregion(fcolor(white)) graphregion(fcolor(white) lcolor(white)) bgcolor(white) text(12000 43 "some text", size(medlarge)) ), saving("price2", replace)

gr combine "price.gph" "price2.gph", plotregion(fcolor(white)) graphregion(fcolor(white)) xsize(7.5) ysize(3.5) ycommon title("Combined")

Thanks a lot

Hi,
if I export the combined graph as png or eps and use it in a latex document, it still has a small grey frame. How can I get rid of this?

[Andrew Musau]

Perhaps you used the scheme s2color when combining the graphs. Note that you are asked to state your version of Stata if it is not the current version (FAQ Advice #11). Try

set scheme s1color
graph combine ...

[Johanna Krenz]

Yes, I just copied Justins code above which is with s2color. With s1color I manage to get rid of the grey frame (I use stata version 17 for mac).
Thanks!
