cmissing having no effect

[Eric Goldstein]

I am trying to create a line graph that does not connect when there are observations with missing data. The cmissing option does not appear to be functioning as I expect it would. Using an example given in a previous answer on this topic (https://www.statalist.org/forums/for...issing-command), I would think the following code would have a line broken in the middle:

webuse grunfeld,clear
replace invest = .  if inrange(year, 1940, 1950)
twoway line invest year if com == 1, cmissing(n)

However, I get a single line with the points connecting

Any help is appreciated.

Yes, I have started getting a similar experience using tsline with cmissing(no). However, if I copy your code into Stata 13 it works as we expect it to work showing the gap. cmissing() was working earlier in version 15.

Updating Stata corrected the problem. Thank you Stata!
