Create a pgfplots chart with two histograms in same plot

Question

Is it possible to create a plot with pgfplots with the histogram of two variables in the same chart, with a different color each?

This an example code I am using, but it creates a histogram where bars are not over each other. It has dummy data.

\documentclass{minimal}

\usepackage{pgfplots}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[
        ybar interval,
        xtick=,
        xticklabel={$\left [ \pgfmathprintnumber\tick, \pgfmathprintnumber\nexttick \right )$},
        axis x line=bottom,
        axis y line=left
    ]
        \addplot+ [hist={data=x, data max=10, data min=0}] table [row sep=\\, y index=0] {
data\\
1 \\
2 \\
3 \\
4 \\
3 \\
4 \\
5 \\
6 \\
4 \\
5 \\
6 \\
3 \\
5 \\
6 \\
7 \\
8 \\
6 \\
8 \\
8 \\
8 \\
3 \\
5 \\
8 \\
};
        \addplot+ [hist={data=x, data max=10, data min=0}] table [row sep=\\, y index=0] {
data\\
1 \\
2 \\
3 \\
7 \\
8 \\
3 \\
5 \\
6 \\
3 \\
8 \\
2 \\
1 \\
6 \\
3 \\
5 \\
8 \\
};
    \end{axis}
\end{tikzpicture}
\end{document}

As mentioned by @stefan-pinnow , this discussion helped in finding that the problem was the interval keyword. The solution then was defining the chart just as ybar:

\documentclass{minimal}

\usepackage{pgfplots}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[
        ybar,
        % xtick=,
        % xticklabel={$\left [ \pgfmathprintnumber\tick, \pgfmathprintnumber\nexttick \right )$},
        axis x line=bottom,
        axis y line=left
    ]
        \addplot+ [opacity=0.5, hist={data=x, data max=10, data min=0}] table [row sep=\\, y index=0] {
data\\
1 \\
2 \\
3 \\
4 \\
3 \\
4 \\
5 \\
6 \\
4 \\
5 \\
6 \\
3 \\
5 \\
6 \\
7 \\
8 \\
6 \\
8 \\
8 \\
8 \\
3 \\
5 \\
8 \\
};
        \addplot+ [opacity=0.5, hist={data=x, data max=10, data min=0}] table [row sep=\\, y index=0] {
data\\
1 \\
2 \\
3 \\
7 \\
8 \\
3 \\
5 \\
6 \\
3 \\
8 \\
2 \\
1 \\
6 \\
3 \\
5 \\
8 \\
};
    \end{axis}
\end{tikzpicture}
\end{document}
