Labeling a bar chart in Latex

Question

I have the following bar Chart in Latex:

\begin{figure}
    \centering
    \begin{tikzpicture}
        \begin{axis}[
            ybar,
            symbolic x coords={CRITICAL, HIGH, MEDIUM, LOW},
            x tick label style={rotate=50, anchor=north east},
            ymin=0, 
            bar width=0.8cm,
            nodes near coords, 
            axis x line=bottom,
            axis y line=left,
            enlarge x limits=1,
            ylabel={Anzahl},
        ]
        \addplot[draw=black, fill=red] coordinates {(CRITICAL, 3)};
        \addplot[draw=black, fill=orange] coordinates {(HIGH, 17)};
        \addplot[draw=black, fill=yellow] coordinates {(MEDIUM, 33)};
        \addplot[draw=black, fill=blue] coordinates {(LOW, 54)};
        \end{axis}
    \end{tikzpicture}
    \caption{Severity from the difference between Grype/Snyk and Docker Scout}
    \label{balkendiagramm_grype_scout}
\end{figure}

I get this:

I would like the text to be centered under the bar. Furthermore, HIGH should also be listed. The last LOW should also be removed. How can I do this?

I think this will help you.

\documentclass{article}
\usepackage{graphicx} % Required for inserting images
\usepackage{subcaption}% Offers an user interface to sub-captions.
\usepackage{float}% Improves the interface for defining floating objects
\usepackage{pgfplots}

\pgfplotsset{compat=newest}

\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}
    \begin{axis}[
        symbolic x coords={
            CRITICAL, 
            HIGH, 
            MEDIUM, 
            LOW},
        xtick={CRITICAL,HIGH,MEDIUM,LOW},
        x tick label style={rotate=50,anchor=east},
        bar width=0.8cm,
        nodes near coords, 
        nodes near coords align={vertical},
        axis x line=bottom,
        enlarge y limits=0.1,
        enlarge x limits=0.2,
        ybar=-0.8cm, % because of bar width=0.8cm
        ymin=0, 
        axis y line=left,
        ylabel={Anzahl},
    ]
    \addplot[draw=black, fill=red]    coordinates {(CRITICAL, 3)};
    \addplot[draw=black, fill=orange] coordinates {(HIGH, 17)};
    \addplot[draw=black, fill=yellow] coordinates {(MEDIUM, 33)};
    \addplot[draw=black, fill=blue]   coordinates {(LOW, 54)};
    \end{axis}
\end{tikzpicture}
