🐛 Suspect a bug in 15.1 is it still happening in Stata 16.0?

[Sergiy Radyakin]

Can anyone having Stata 16 already check if the following is occurring in it? Because in 15.1 the following code requires dropping one graph before plotting another, and I don't see any reason for that:

version 15.1
clear all
sysuse nlsw88

graph hbar wage, over(union) over(occu) asyvar ///
   legend(pos(2) col(1) size(*.5)) ///
   name("legend")
   
 graph drop _all // strangely the code works only with this line enabled
   
graph hbar wage, over(union) over(occu) asyvar ///
   legend(pos(2) col(1) size(*.5)) ///   
   bar(1, fc(orange)) bar(2, fc(green)) ///
   name("colors")

If the highlighted line is commented out - the second graphing statement results in error 198:
option(s) labelstyle( size(*.5)) not allowed

Or is it, perhaps, something obvious that I've missed again?

Thank you, Sergiy

The problem appears to be naming the first graph -legend-. If you changed it to -mylegend- it runs without issue. Why that problem would carry over to the second graph I am not sure, but if you simplify the second graph you get a return code of 4023:

. version 15.1

. clear all

. sysuse nlsw88
(NLSW, 1988 extract)

. 
. graph hbar wage, over(union) over(occu) asyvar ///
>    legend(pos(2) col(1) size(*.5)) ///
>    name(legend, replace)

.    
. // graph drop _all // strangely the code works only with this line enabled
. 
. graph hbar wage
rebuild: class member function not found
r(4023);

end of do-file

Dear Scott,
thank you for your advice.
Changing the name to a different one has helped.
