Issues with legend when exporting graphs as pdf

[Shreya Dutt]

Hi,

When I export the following graph to pdf, the legend section is getting distorted. I am using Stata 16. Does anyone have any solutions?

twoway (histogram speed_notraffic if check==1, by(cityname_corrected, note("")) yla(`labels') color(blue%40) subtitle(, fcolor(white) lstyle(none))) ///        
       (histogram speed_notraffic if check==0, by(cityname_corrected, note("") ixaxes iyaxes imargin(b+5)) yla(`labels') color(yellow%60) subtitle(, fcolor(white) lstyle(none))), ///  
       legend(order(1 "March to June 2020" 2 "March to June 2021" ) region(lstyle(none))) ysize(8) xsize(6) plotregion(lcolor(white))
      
graph export "${resultsdir}/uncongested/histogram_marchjune2020_marchjune2021_by_city.pdf", replace as(pdf)

Graph display in Stata:

Someone else might have an explanation as to why that is, but I would think one approach to overcome this issue might be to add size(vsmall) symxsize(*.5) to the legend() call
