我想制作一个堆叠图，其中 xticks 显示样本数量。但我的 xticks 介于间隔之间，无论我怎么尝试都无法修复。更奇怪的是，我有 21 个样本，但图表只显示 20 个作为最后一个。这是我的代码：
\begin{figure}[bh]
\begin{tikzpicture}
\begin{axis}[
ybar stacked,
xtick = data,
xmin=1, xmax=21,
%xtick = {1,...,22},
%x tick label as interval = false,
%xticklabels = {1,...,22},
%xtick distance = 2
%xticklabels={1,, ,, ,, ,, ,,10,, ,, ,, ,, ,,21,,},
%xtick distance = 1,
%xlabel near ticks,
enlargelimits=true,
ybar interval=0.05,
bar width = 0.14cm
]
\addplot[ybar,fill=red]
coordinates {(1,30)
(2,30)
(3,30)
(4,80)
(5,50)
(6,40)
(7,90)
(8,30)
(9,80)
(10,50)
(11,85)
(12,75)
(13,35)
(14,50)
(15,40)
(16,50)
(17,80)
(18,30)
(19,10)
(20,80)
(21,80)
};
\addplot[ybar,fill=green]
coordinates {(1,52)
(2,61)
(3,53)
(4,54)
(5,62)
(6,64)
(7,57)
(8,45)
(9,45)
(10,46)
(11,54)
(12,57)
(13,52)
(14,63)
(15,50)
(16,51)
(17,47)
(18,57)
(19,33)
(20,30)
(21,58)
};
\end{axis}
\end{tikzpicture}
\end{figure}

像这样？
\documentclass[margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}
\begin{document}
\begin{tikzpicture}
\begin{axis}[width=12cm,
ybar stacked,
bar width = 3mm,
xtick = {1,...,21},
xticklabels = {1,...,21},
x tick label style = {font=\scriptsize},
enlargelimits=0.05,
