如何删除甘特图中多余的空白水平网格线？

Question

我对甘特图中出现的额外空白水平网格线感到有些问题。这是代码：

\documentclass[a4paper, 11pt]{article}

\usepackage{pgfgantt}


\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{enumerate}
\usepackage{eurosym}
\usepackage[hidelinks, hyperfootnotes=false]{hyperref}
\usepackage{amsmath}
\usepackage{enumitem}
\usepackage{fancyhdr}
%\usepackage{pagecounting}
\usepackage{float}
\usepackage{ifoddpage}
\usepackage[inner=25mm, outer=25mm, bottom=25mm, top=25mm]{geometry}
\usepackage{lastpage}
\usepackage{scrextend}
\usepackage{csquotes}
\usepackage[style=verbose-note,firstinits=true,doi=false, eprint=false, sorting=none, maxbibnames=99, maxcitenames=99]{biblatex}

\begin{document}


\begin{figure}[h]
%\hspace*{-20px}
\begin{ganttchart}[vgrid={*1{black}},hgrid={*1{black}}, x unit=0.6cm, y unit chart=0.5cm, bar top shift = -0.295mm,bar label node/.append style={align=left}]{1}{24}
{\fontsize{8}{10}\selectfont
\gantttitlelist{1,...,24}{1}\\
\ganttbar[bar height=0.24mm,bar/.append style={fill=gray!20}]{1}{1}{4}\\
\ganttbar[bar height=0.24mm,bar/.append style={fill=gray!20}]{2}{5}{5}\\
\ganttbar[bar height=0.24mm,bar/.append style={fill=gray!20}]{2}{6}{8}\\
\ganttbar[bar height=0.24mm,bar/.append style={fill=gray!20}]{4}{9}{10}
}
\end{ganttchart}
\end{figure}

\end{document}

这是我得到的输出：

Answer 1

您“创建”了它，并通过 转移后看到了它bar top shift = -0.295mm,。

为了看到它，我做了以下事情：

• 删除了这里不需要的所有包
• 将条形图作为宏（简写符号）进行比较
• （%最后的避免在“执行”时插入不需要的空格）
• 注释掉你的甘特图选项，直到找到问题根源
• （为此我逐行放置它们以便%根据需要删除
• 显示没有和有的结果 bar top shift = -0.295mm,

\documentclass[a4paper, 11pt]{article}

\usepackage{pgfgantt}

% removed packages, which are not needed here

\newcommand\bars[0]{% for short-hand notation
