problem with legend

[Nader Mehri]

Using the below codes, I could create three graphs and combine them into one nice graph. As shown in the below image, the position and appearance of the legend is not quite right. I would like to have the legend right below the combined graphs. Also, I was wondering if there is any way to wrap up the code using a loop.

twoway kdensity TLE_50_511 || kdensity TLE_50_512 || kdensity TLE_50_513, xtitle("Total Life Expectancy (TLE)") legend(off) name(gr1, replace)

twoway kdensity HLE_50_511 || kdensity HLE_50_512 || kdensity HLE_50_513, legend( pos(6) rows(1) bmargin(large) order (1 "Married non_caregiver" 2 "Spouse caregiver <14h/w" 3 "Spouse caregiver >=14h/w")) xtitle("Healthy Life Expectancy (HLE)") name(gr2, replace)


twoway kdensity PLE_50_511 || kdensity PLE_50_512 || kdensity PLE_50_513, xtitle("PLE (HLE/TLE)") legend(off) name(gr3, replace)

graph combine gr1 gr2 gr3 , ///
rows(1) xsize(12.5) ysize(6)

You will always have a scaling problem if you include a legend in some graphs and not others and then combine them. This uses grc1leg by Vince Wiggins and is not tested as you do not provide a reproducible example.

local optsTLE "xtitle("Total Life Expectancy (TLE)") legend(off) name(gr1, replace)"
local optsHLE "legend( pos(6) rows(1) bmargin(large) order (1 "Married non_caregiver" 2 "Spouse caregiver <14h/w" 3 "Spouse caregiver >=14h/w")) xtitle("Healthy Life Expectancy (HLE)") name(gr2, replace)"
local optsPLE "xtitle("PLE (HLE/TLE)") legend(off) name(gr3, replace)"

foreach var in TLE HLE PLE{
tw kdensity `var'_50_511 || kdensity `var'_50_512 || kdensity `var'_50_513, `opts`var''
}
net install grc1leg, from (http://www.stata.com/users/vwiggins)
grc1leg gr1 gr2 gr3 ,rows(1) xsize(12.5) ysize(6) legendfrom(gr2)

Thanks. Below is the combined graph using your code. Graph #1 is exactly the same as post#1 but two others are different. Also, the appearance of the legend does not look readable enough. Is there any way to fix this.

It seems that you need to adjust the x axis in both graphs and you could have a legend spanning multiple rows as it is too long. If you provide a data example, I can attempt to tidy up. Otherwise, I do not combine graphs often, so the modifications are not apparent to me.
