# Should the tag of a derived package (pgfplots)'s parent package (tikz-pgf) also be applied?

Recently, I've seen some questions about pgfplots posted that were only tagged at the time of posting:

I've been editing the tags to add , of course. But I'm wondering if leaving adds anything for questions strictly about pgfplots. pgfplots is built on top of TikZ/pgf, but it has its own set of commands, keys, and conventions.

To be sure, there are questions that concern aspects of both packages (using \draw and \node commands inside axis environments, for instance), and for these, both tags make sense.

Should questions about only pgfplots functionality (for example, \addplot commands and keys defined in pgfplots itself) be tagged simply or including both and ?

• I agree, for questions that are only concerned with PGFPlots and not with the interaction between PGFPlots and "just" TikZ, there's no use in having the tikz-pgf tag. – Jake Mar 10 '15 at 19:29
• Me too but other than us retagging I don't know any other way to explain the difference to users. My colleague after almost 3 years still says: I drew this plot in TikZ – percusse Mar 11 '15 at 10:34
• @percusse By a better UI. PGFplot is currently enclosed in \begin{tikzpicture}\begin{axis} .... – yo' Mar 12 '15 at 18:21
• @yo' You can still do many cool stuff before and after axis environment and within TikZ picture. So it is for a reason. – percusse Mar 12 '15 at 20:46
