为 tikzpicture 垂直条添加背景图案

Question

如何分别用对角线和网格图案替换图片中所示的蓝色背景？

我目前无法找到适合我这种图表的简洁解决方案。

代码

\begin{tikzpicture}
    \begin{axis}[
        ybar,
        bar width=1.0cm,
        enlargelimits=0.75,
        width=7.5cm, 
        height=6cm,
        xlabel={Predictive models}, ylabel style={align=center},
        ylabel={Predicitve accuracy (\%)},
        symbolic x coords={ensemble voting, lung cancer calculator},
        xtick=data, 
        xticklabel style={text width=2cm, align=center}
    ]
    \addplot coordinates {
        (lung cancer calculator,91.2)
        (ensemble voting,91.4)
    };
    \end{axis}
\end{tikzpicture}

\addplot您可以在选项中使用 TikZ 绘图选项。

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.8}
\usetikzlibrary{patterns}
\begin{document}

\begin{tikzpicture}
    \begin{axis}[
        ybar,
        bar width=1.0cm,
        enlargelimits=0.75,
        width=7.5cm, 
        height=6cm,
        xlabel={Predictive models}, ylabel style={align=center},
        ylabel={Predicitve accuracy (\%)},
        symbolic x coords={ensemble voting, lung cancer calculator},
        xtick=data, 
        xticklabel style={text width=2cm, align=center}
    ]
    \addplot[pattern=crosshatch] coordinates {
        (lung cancer calculator,91.2)
        (ensemble voting,91.4)
    };
\end{axis}
\end{tikzpicture}

\end{document}
