[Tex/LaTex] Axis discontinuity + enlargelimits not showing axis correctly in pgfplots

pgfplots

I need to make a y-axis discontinuity, but I also need to configure enlargelimits=true. The problem is that the axis is not showing correctly, as the below picture show. If I set enlargelimits=false, then the axis discontinuity is correctly done, but the axis values are messed up, as the above picture shows. How can I fix my plots?

Here is the MWE of the picture:

It seems, as if this is not possible. All examples for discontinuities in the pgf manual are using the option \enlargelimits=false. However, you can just do it manually. \enlargelimits=true increases the limits by 10 % to both sides, so just use xmin and xmax to specify what ever you need.

Some notes:

If you leave xtick=data away, it looks much better (imho).
the default for \enlargelimits= is true. However, the result looks the same when you comment this option. Looks a bit like a bug to me or I am not seeing some documentation...
I would recommend to insert a \end{figure}\begin{figure}\centering between the two figures or to use the package subcaption in order to nicely set two images in one float.

I also corrected:

begin{center} to \centering
\pgfplotsset{compat=1.10} as requested in the warnings
\ymintick in order to set the first tick above the crunshing.

[Tex/LaTex] Discontinuity of log axis in pgfplots

You can use a decoration to place the axis discontinuity. The decoration in the example below is adapted from Draw the discontinuity symbol with tikz.

\documentclass{standalone}
\usepackage{pgfplots}
\pgfdeclaredecoration{discontinuity}{start}{
  \state{start}[width=0.04\pgfdecoratedinputsegmentremainingdistance-0.5\pgfdecorationsegmentlength,next state=up from center]
  {}
  \state{up from center}[width=+.5\pgfdecorationsegmentlength, next state=big down]
  {
    \pgfpathlineto{\pgfpointorigin}
    \pgfpathlineto{\pgfqpoint{.25\pgfdecorationsegmentlength}{\pgfdecorationsegmentamplitude}}
  }
  \state{big down}[next state=center finish]
  {
    \pgfpathlineto{\pgfqpoint{.25\pgfdecorationsegmentlength}{-\pgfdecorationsegmentamplitude}}
  }
  \state{center finish}[width=0.5\pgfdecoratedinputsegmentremainingdistance, next state=do nothing]{
    \pgfpathlineto{\pgfpointorigin}
    \pgfpathlineto{\pgfpointdecoratedinputsegmentlast}
  }
  \state{do nothing}[width=\pgfdecorationsegmentlength,next state=do nothing]{
    \pgfpathlineto{\pgfpointdecoratedinputsegmentlast}
  }
  \state{final}
  {
    \pgfpathlineto{\pgfpointdecoratedpathlast}
  }
}

\begin{document}
\begin{tikzpicture}
\begin{semilogxaxis}[
 log basis x=2,
 log origin=infty,
 y=0.5cm,
 legend style={at={(0.5,1.1)},anchor=south},
 legend columns=-1,
 ytick={one,two,eight,sixty-four},
 symbolic y coords={one,two,eight,sixty-four},
 bar width=7pt,
 enlarge y limits=0.5,
 enlarge x limits={0.15},
 separate axis lines,
every outer x axis line/.append style=
{decoration={discontinuity, segment length=3mm}, decorate},
]

\addplot+[xbar] coordinates {(1,one)};
\addlegendentry{one}

\addplot+[xbar] coordinates {(2,two)};
\addlegendentry{two}

\addplot+[xbar] coordinates {(8,eight)};
\addlegendentry{eight}

\addplot+[xbar] coordinates {(64,sixty-four)};
\addlegendentry{sixty-four}

\end{semilogxaxis}
\end{tikzpicture}
\end{document}

In my eyes, a better alternative to a discontinuity symbol on a logarithmic axis (which really doesn't make any sense mathematically) would be to use a scatter plot. To show that the data is essentially one-dimensional, you could use a y grid:

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{semilogxaxis}[
 log basis x=2,
 log origin=infty,
 y=0.5cm,
 legend style={at={(0.5,1.1)},anchor=south},
 legend columns=-1,
 ytick={one,two,eight,sixty-four},
 symbolic y coords={one,two,eight,sixty-four},
 bar width=7pt,
 enlarge y limits=0.5,
 enlarge x limits={0.15},
 ymajorgrids=true
]

\addplot coordinates {(1,one)};
\addlegendentry{one}

\addplot coordinates {(2,two)};
\addlegendentry{two}

\addplot coordinates {(8,eight)};
\addlegendentry{eight}

\addplot coordinates {(64,sixty-four)};
\addlegendentry{sixty-four}

\end{semilogxaxis}
\end{tikzpicture}
\end{document}

[Tex/LaTex] plotting two time series with bounds

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:
