[Tex/LaTex] PGF barplot with two y axis

bar chartpgfplotstikz-pgf

I added a new axis to my barplot and that has a different scale as the first one.
The second axis is shifted and does not have the same height as the first one.
What do I need to change so that the right Y-Axis is not shifted and the line goes from the left to the right axis?
My Code so far:

        \legend{Data1, Data2}
    \end{axis}

    \addplot[style={green,fill=green,mark=none}]

You have to use same attributes to the y ticks in both the axis like

        scaled y ticks = false,
        ymin=-0.1,ymax=40,

and remove scale only axis, too. Further, you have to plot all bars inside the same axis environment so that they are properly spaced. I have commented out the lines that are not necessary and we keep the second axis environment just for the right y axis. Also, I have drawn the second x axis and used axis on top so that bars don't cover the x axis. So many changes that I can't write on all of them. Please see the code.

[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:

You can use

 y filter/.expression={y==0 ? nan : y}

in the options of \addplot.
