Latex - 放置和调整直方图的大小

Question

我可以在同一页上（实际上是同一张图片中）放置多个箱线图，但垂直方向的直方图不能超过 2 个，水平方向的直方图只能超过 1 个。如何调整直方图的大小并设置每条水平线上可以容纳的数量？也许一对应该放在一个段落中？这种格式有标准样式建议吗？

理想情况下，我希望每行并排显示 2 个直方图，每页显示 6 行。这样，我每页就能看到 6 个月的舒张压和收缩压读数。我希望能够确定自两年前心脏病发作以来每日血压读数的趋势，并向医生咨询。

数据文件是一列数字：

151
103
118
...
148

用于创建直方图的 tex 只是从 pgfplots 手册中提取出来的，有几行我不明白，但它运行得很好：

\begin{tikzpicture}
\begin{axis} [
title={September 2016},
ybar interval, % I don't think I need this line
xtick=, % I don't think I need this either
xticklabel= % I think this just gives a nicer font
{$ [ \pgfmathprintnumber\tick,%
\pgfmathprintnumber\nexttick)$}
]]

\addplot+[hist={data=x, bins=100}]
file {"c:/Documents and Settings/Dad/Desktop/bloodPressure/histsystolic_September2016.txt"};
\end{axis}
\end{tikzpicture}

非常感谢您的帮助。

所以您的意思是下面这样？

（我只是在这里绘制随机数据，因为您自己没有提供合适的数据。）
