pgfplots-将高于给定值的条形图部分涂成不同的颜色

Question

我编写了下面的乳胶命令来生成屏幕截图中显示的条形图。

接下来我想做的是将条形图的每个突出显示的尖端涂上更深的颜色，如图所示。这也可以通过使用 addplot + 坐标来实现吗？

试试这个（你的其他包都是不需要的）：

\documentclass[]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{pgfplots}


\begin{document}

    \begin{center}
        \begin{tikzpicture}

                scale only axis,

        \addplot[fill=blue] coordinates {(2,0.35) (20,.7) (9,1.05)};

            \end{axis}
        \end{tikzpicture}
