    Welcome to TeX.SE. It's helpful that you have added your code, however it is very long and contains many things that are not relevant for the issue. This makes it harder to answer because it is not clear where to look. Maybe you can edit the code to remove anything that is unrelated, like color definitions, minipages, tabular column definitions, all packages that are not pgfplots, any axis option that does not influence the issue. Make sure it still compiles after you have removed everything. You could also add a screenshot to illustrate what the problem is.

  • Remove text width=1.5cm,anchor=north east from your definition of x tick label style.

Your example code can be drastically simplified to the following MWE that still shows the alignment issue:

\documentclass[12pt]{article}

\usepackage{pgfplots}
\usepgfplotslibrary{units}

\begin{document}

\begin{tikzpicture}
\pgfplotscreateplotcyclelist{defaultCycle}{ybar interval}
\begin{axis}
[   cycle list name=defaultCycle,
    x tick label style ={font=\normalsize,text width=1.5cm,anchor=north east,rotate=0,align=center},
    y tick label style ={font=\normalsize,text width=2cm,anchor=east,rotate=0,align=right},
    ]
        \addplot+ table [x={x},y={y},col sep=semicolon] {
        x;  y;  z
        -6; 25; 0
        2;  22; 0
        9;  14; 0
        17; 14; 0
        };
\end{axis}
\end{tikzpicture}


\end{document}

enter image description here

Let's add draw=red to the x tick label style and we get the following output:

enter image description here

As one can see from the above image, each number is placed inside of a box that is 1.5cm wide. Numbers are horizontally centered within their box, and each boxes upper right corer is aligned with the corresponding tick, since youused text width=1.5cm and anchor=north east. Removing the two before mentioned options from the definition of x tick label style results in:

Applied to your example code, one ends up with the following:

  • this is very helpful but it still doesn't make the actual xticks line up with the bar lines

  • I apparently misunderstood your question.Could you add a sketch of the expected output to your question?

  • As far as I can tell, the ticks don't line up with the outlines of the bars since the numbers don't match. You have an x tick at -5 but a bar that has an x value of -6. What kind of output/alignment do you expect?

  • i want the bar to match the xtick so the -6 should line up with the bar

  • i have also added an expected output, the numbers in the image are just exemplary

Seems you want xtick=data, in additiion to removing your xticklabel style as Ieandriis described.
