Wie umgeht man das Problem in der Farbdarstellung von pgfplots bei visible ?

\documentclass[10pt]{beamer}

\usepackage{pgfplots}

\tikzset{
  invisible/.style={opacity=0},
  visible on/.style={alt={#1{}{invisible}}},
  alt/.code args={<#1>#2#3}{%
    \alt<#1>{\pgfkeysalso{#2}}{\pgfkeysalso{#3}} % \pgfkeysalso doesn't change the path
  },
}
