如何修复 tikzpicture 代码中的问题？

我已经使用 geogebra 创建了 tikzpicture 代码，但尺寸太大，超出了页面大小。我尝试进行一些更改，但图形被打乱了。如何解决这个问题。我需要有关更改代码的建议。

答案1

您可以尝试x post scale=0.5缩小y post scale=0.5轴。

注意：我在下面的代码中将\draw [fill=uuuuuu] (7.,0.) circle (2.0pt);其改为，因为它会产生错误。可能是由于您没有提供前言，所以出现了一些软件包错误。\draw [fill=black] (7.,0.) circle (2.0pt);

编辑：要缩小整个图片，您可以使用包\adjustbox{max width=\textwidth}{content}中的图片adjustbox。见下文。

编辑：Adjustbox：将图片尺寸缩小至文本宽度。
