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?
