Hi everybody!


I am using Stata 17. While running the code below:

HTML Code:
sysuse auto, clear
    
reghdfe price headroom weight , absorb(i.trunk)  resid
predict y_hat, res
    
twoway (lpolyci price headroom,  n(100) ciplot(rline) pstyle(ci2) lcolor(lavender) lwidth(medthick)  blpattern(dash)   )
I obtain a graph, while my colleague, who runs exactly the same code from another laptop (which has Stata 15) gets a different graph.

I tried to solve the issue by putting "version 15:" in front of the graph, but it did not work. I could not find a workaround for this problem on Google. Does anybody know what I can try?

Thank you very much in advance!
