Histogram fill with logarithmic scale

Question

I face a "filling" problem when I run one of the pgfplots example but with y-log scale. Here is the MWE

\documentclass{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
  \begin{semilogyaxis}[ymin=0,ymax=1,enlargelimits=false]
    \addplot
      [const plot,fill=blue,draw=black]
      coordinates
        {(0,0.1)    (0.1,0.15)  (0.2,0.5)   (0.3,0.62)
         (0.4,0.56) (0.5,0.58)  (0.6,0.65)  (0.7,0.6)
         (0.8,0.58) (0.9,0.55)  (1,0.52)}
  \closedcycle;
  \end{semilogyaxis}
\end{tikzpicture}
\end{document}

Here is the output result

I also try to change the minimal value of y since logarithm of 0.0 is undefined but it does not help.

You can set the origin for logarithmic plots to always be at the bottom edge of the plot, by using log origin y=infty. This will affect the path drawn by \closedcycle, and define where plot styles like ybar and ycomb start. By default, the origin is set to log origin y=0.

\documentclass{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
  \begin{semilogyaxis}[
    ymin=0.05,
    ymax=1,
    log origin=infty,
    enlargelimits=false
  ]
    \addplot
      [const plot,fill=blue,draw=black]
      coordinates
        {(0,0.1)    (0.1,0.15)  (0.2,0.5)   (0.3,0.62)
         (0.4,0.56) (0.5,0.58)  (0.6,0.65)  (0.7,0.6)
         (0.8,0.58) (0.9,0.55)  (1,0.52)}
  \closedcycle;
  \end{semilogyaxis}
\end{tikzpicture}
\end{document}
