[Tex/LaTex] pgfplots – bar chart with bars starting at -120 instead of 0

pgfplots

I would like a plot like the one here shown (wanted)
As using ybar, the origin is fixed at 0, I'm getting a plot with the bars starting from zero instead of -120.

You can shift the labels with an offset

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\pgfplotstableread{
a b c
1 10 20
2 45 130
3 30 60
}\mytable
\begin{document}
\begin{tikzpicture}
\begin{axis}[ybar,xtick=data,enlarge y limits={upper=5},ymin=0,
yticklabel={\pgfmathparse{\tick-120}\pgfmathprintnumber{\pgfmathresult}}]
\addplot table[x=a,y=b] {\mytable};
\addplot table[x=a,y=c] {\mytable};
\end{axis}
\end{tikzpicture}
\end{document}

By default, all the markers are drawn in one layer on top of the plots. This is done so clipping for them can be switched on or off independently from the normal clipping. You can tell PGFPlots to use an individual layer for each set of markers, instead of putting them all on the same topmost layer, by setting clip mode=individual. This means that later plots will be drawn on top of the preceding markers, which is what you want in this case:

\documentclass{standalone}
\usepackage{tikz} 
\usepackage{pgfplots}
\pgfplotsset{compat=1.6}

\begin{filecontents}{TableForErrorBarQuestion.txt}
xValue1 yValue1 Deltay1     xValue2 yValue2 Deltay2

I would really not recommend this plot because basically it's not readable and all data is dominated by Step 3 and predicted ones. First the question,

The plot goes up because you enlarge both limits, you need enlarge x limits=0.15,
I didn't get that error with your code.
You can do that via both declaring a width and a height dimension.

I cleaned up a bit, the code and the result is

As you can see, most of your data vanished and you have strange entries in your legend because those datasets are invisible.

Instead I can think of two options,

clean up the legend and mention only step3, step 5+6, and predicted columns with a disclaimer that the remaining step contribution is negligible and comparable
Combine your negligible entries into a sum and plot that but I can't judge whether it would be a good idea here for your application.
