这是对前两个问题的后续回答：
1：使用 pgfplots 和 tikzscale 的字体大小缩放和节点放置问题
2：将多列TikZ / pgfplots groupplot缩放到页面宽度
我想将多列组图缩放到一定宽度（通常为\textwidth
），同时保持字体大小和节点位置不变。从问题 1 中我了解到，使用时tikzscale，不应为环境定义hight和/或，以保持字体大小和节点位置不变。问题 2 的答案是，我应该使用来缩放到所需的整体宽度。但如果没有定义和，那么和的组合将产生错误： widthaxistikzscalegroupplotshightwidthgroupplottikzscale
！包 pgfplots 错误：错误：绘图高度“-77.46211pt”太小。在保持标签大小不变的情况下无法实现此操作。抱歉，标签大小仅为近似值。您需要调整高度。
绘图将无法正确缩放。
我的问题的简短版本是：“如何将多列组图缩放到一定宽度，同时仍保持字体大小和节点位置？”
以下 MWE 说明了这个问题。

Manually scaling height and width of the plots requires a lot of tries until an ``acceptable'' result is reached. At least the font size and node placement are correct.
\includegraphics[width=250pt]{A.tikz}
Width and height are defined and tikzscale is used. The plots scale nicely to the desired width, but font size and node placement problems occur.
\input{B.tikz}
Without defined height and width and without tikzscale, the plots are too large to fit the desired textwidth. Font size and node placement work fine.
\includegraphics[width=250pt]{B.tikz}
No definition of width and height, but using tikzscale will produce an error. The plot is not scaled correctly but font size and node placement look fine.

答案1
免责声明：这不是一个完整的答案，因为它只涉及绘图宽度、标签字体大小等，而不涉及节点大小和位置。不幸的是，作为评论，它太长了。
groupplots我发现通过补偿图之间的水平间距可以获得适当的字体大小。
您的\includegraphics命令仍通过选项调用width=\textwidth，但环境内每个图的宽度groupplots必须设置为1/x*\textwidth-y，其中x是水平放置的组图数，y是指定的水平分隔。
输出：
据我所知，tikzscale-d 数字的宽度接近完美，并且字体没有扭曲。
但不幸的是，这也不能解决节点放置问题。我希望这是一个很好的起点，其他人可以为您提供帮助。我tikzscale也经常使用，如果有一个强大的扩展解决方案就太好了groupplots。
