[Tex/LaTex] How to add multiple x axes with different scaling

pgfplots

I am trying to plot the following graph (Standard Atmosphere) with pgfplots:

What I currently have is:

\documentclass[]{article}
\usepackage{pgfplots,amsmath}

\begin{document}
\begin{tikzpicture}
    \pgfplotsset{    
    every axis x label/.style={
    at={(ticklabel* cs:1.05)},
    yshift = -7.5pt,
    anchor=west,},
    width=14cm,
    every axis y label/.style={at={(current axis.above origin)},
    anchor=north east,
    yshift = 1cm,} }
    \begin{axis}[
    scaled y ticks = false,
      y tick label style={/pgf/number format/fixed,
      /pgf/number format/1000 sep = \thinspace % Optional if you want to replace comma as the 1000 separator 
      },
      xmin=0,xmax=1400,
      xlabel={$p ~\text{[mbar]}$},
      ylabel={$H ~\text{[m]}$},
      ymin=0, ymax=32000,
      ytick={0, 4000, 8000, 12000, 16000, 20000, 24000, 28000, 32000},
      xtick={0,200,400,600,800,1000,1200,1400},
      ymajorgrids=true, xmajorgrids=true,
      axis y line*=left, axis x line*=bottom]
      \addplot[color=red,smooth,thick] coordinates { 
      (1013.25, 0) (616.4,4000) (356.0,8000) (193.3,12000) (102.9,16000) (54.7,20000) (29.3,24000) (15.9,28000) (8.7,32000) };
      \addplot[color=black, dashed,very thick] coordinates {(0,11000) (1400,11000)};
      \addplot[color=black, dashed, very thick] coordinates {(0,20000) (1400,20000)};
    \end{axis}
    \begin{axis}[

        hide y axis,
         axis x line*=bottom,
        x axis line style= { draw opacity=0 },
        ymin=0, ymax=32000,
        xlabel={$\rho ~[\text{kg}/ \text{m}^3]$} ]
    \addplot[color=blue,yshift=0.8cm,smooth,thick] coordinates { 
      (1.225,0) (0.82,4000) (0.53,8000) (0.31,12000) (0.17,16000) (0.09,20000) (0.05,24000) (0.02,28000) (0.013,32000) };
    \end{axis} 
      \begin{axis}[
        xmin=160,xmax=300,%--- CF
        yshift=-1.6cm,%-- CF
        xtick={160,180,200,220,240,260,280,300},
        hide y axis,
        axis x line*=bottom,
        x axis line style= { draw opacity=0 },
        ymin=0, ymax=32000,
        xlabel={$T ~\text{[K]}$} ]
    \addplot[color=black,yshift=1.6cm,thick] coordinates { 
      (288.150,0) (262.150,4000) (236.150,8000) (216.650,11000) (216.650,12000) (216.650,16000) (216.650,20000) (220.650,24000)(224.650,28000)(228.650,32000) };
    \end{axis}   
\end{tikzpicture}

\end{document}

I've used sample codes from similar questions and tweaked a bit. I managed to shift the 2nd and 3rd x axes in negative y-direction which I'm happy about. However, my results also shifted. Note that they have different scaling.

Is there a solution for this problem?

You should not shift the whole environment axis, but only the x axis labels themselves:

\begin{tikzpicture}
    \pgfplotsset{    
    every axis x label/.style={
    at={(ticklabel* cs:1.05)},
    yshift = -7.5pt,
    anchor=west,},
    width=14cm,
    every axis y label/.style={at={(current axis.above origin)},
    anchor=north east,
    yshift = 1cm,} }
    \begin{axis}[
    scaled y ticks = false,
      y tick label style={/pgf/number format/fixed,
      /pgf/number format/1000 sep = \thinspace % Optional if you want to replace comma as the 1000 separator 
      },
      xmin=0,xmax=1400,
      xlabel={$p ~\text{[mbar]}$},
      ylabel={$H ~\text{[m]}$},
      ymin=0, ymax=32000,
      ytick={0, 4000, 8000, 12000, 16000, 20000, 24000, 28000, 32000},
      xtick={0,200,400,600,800,1000,1200,1400},
      ymajorgrids=true, xmajorgrids=true,
      axis y line*=left, axis x line*=bottom]
      \addplot[color=red,smooth,thick] coordinates { 
      (1013.25, 0) (616.4,4000) (356.0,8000) (193.3,12000) (102.9,16000) (54.7,20000) (29.3,24000) (15.9,28000) (8.7,32000) };
      \addplot[color=black, dashed,very thick] coordinates {(0,11000) (1400,11000)};
      \addplot[color=black, dashed, very thick] coordinates {(0,20000) (1400,20000)};
    \end{axis}
    \begin{axis}[
        xmin=0,xmax=1.4,%--- CF
        xtick={0,0.2,0.4,0.6,0.8,1.0,1.2,1.4},
        hide y axis,
         axis x line*=none,
        ymin=0, ymax=32000,
        xlabel={$\rho ~[\text{kg}/ \text{m}^3]$},
        x label style={yshift=-0.8cm},
        x tick label style={yshift=-0.8cm}
        ]
    \addplot[color=blue,smooth,thick] coordinates { 
      (1.225,0) (0.82,4000) (0.53,8000) (0.31,12000) (0.17,16000) (0.09,20000) (0.05,24000) (0.02,28000) (0.013,32000) };
    \end{axis} 
      \begin{axis}[
        xmin=160,xmax=300,%--- CF
        xtick={160,180,200,220,240,260,280,300},
        hide y axis,
        axis x line*=none,
        ymin=0, ymax=32000,
        xlabel={$T ~\text{[K]}$},
        x label style={yshift=-1.6cm},
        x tick label style={yshift=-1.6cm}
        ]
    \addplot[color=black,thick] coordinates { 
      (288.150,0) (262.150,4000) (236.150,8000) (216.650,11000) (216.650,12000) (216.650,16000) (216.650,20000) (220.650,24000)(224.650,28000)(228.650,32000) };
    \end{axis}   
\end{tikzpicture}

Note that you have to shift the tick labels (x tick label style) as well as the x axis label (x label style) by the same amount.

[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:
