Re: [Pgfplots-features] Problem with legend, again

[Christian F. <cfe...@go...>]

Hi Ihor,

this is effectively the same problem as with the text depth: the legend 
style is inherited by your plot mark.

The only way to solve it is to set all involved options explicitly. In 
this case, the option "anchor=center" fixes the problem:

\pgfdeclareplotmark{e}
   {\filldraw[fill=white,draw=black] (0pt,0pt) circle [radius=3pt]
     node[anchor=center,text depth=0pt] {\scriptsize e};}


Kind regards

Christian
