如何绘制小条与长条的组合？

Question

所有组中的第一个条形不可见。如何使其可见？

这是不起作用的 MWE。

我想要一个与以下类似且具有相同 yticks 的条形图：

Answer 1

由于条形图的高度层次较大，因此您可能需要使用对数图。可以通过调整按键来控制刻度标签和刻度。

\documentclass{article}
\usepackage[a4paper, left=1in, right=1in, top=1.5in, bottom=1.5in]{geometry}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepackage{subcaption}

\usetikzlibrary{patterns}

\pgfplotsset{compat=1.11, width=10cm, height=7cm,
    /pgfplots/ybar legend/.style={
        /pgfplots/legend image code/.code={%
            \draw [#1] (0cm,-0.1cm) rectangle (0.6cm,0.1cm);},
    },
}

\begin{document}


\pgfplotstableread[col sep=comma]{

    workload,       EMRSAY,     L-BOUND,    L-MSPAN
    {128M,64R},     0.004,      0.4,        0.4
    {128M,128R},    0.005,      0.6,        0.6
    {256M,64R},     0.006,      0.8,        0.8

不绘制 y 轴刻度：
