Graphic with STATA 14: named style % 40 not found in class color

[Morgane Monjour]

Dear users,

I am using STATA 14 and I want to produce a graphic with a line and faded color for the confidence interval, but I only have a dark grey block.
I have the following message: (note: named style % 40 not found in class color, default attributes used)

I reproduced codes so I know that the codes are not the problem but it is more related to my stata setting.

Do you know if I need to download a package or more generally what can I do to fix this ?

Thank you very much for your help.

Best regards,

Morgane

Opacity is a Stata 15 technology. You need to upgrade your version of Stata to enjoy it.
