如何去掉编译后的文档中显示的“1.2.11.2.1”？

我正在使用 Overleaf 中的课程编写讲义report。我想添加之前在另一个文档中制作的图表（名为图 1.2.1），并将其上传到main.tex。我使用了import，结果发生了这种情况。

文本

这是我当时的代码：

We call set $C$ the graph of the function $y=f(x)$. The figure below is a graph of the function $f(x)=x^2$ defined over all real numbers.

\import{figures/}{fig 1.2.1}

这是我的代码fig 1.2.1.tex。

1.2.11.2.1 出现在图表之前，我找不到删除它的方法。

TikZ如果我的代码给您带来任何困扰，我深感抱歉。由于我最近才开始探索和的世界pgfplots，因此非常欢迎对我的代码提出任何建议和更正。

答案1

我认为您的代码不能正常工作 :) 首先，在图中您有，这是错误的。如果您想指定形状，则 的draw=rectangle参数应该是颜色名称。但是，是默认值，因此如果您没有更改默认值，您可以直接执行。drawdraw, rectanglerectangledraw

其次，我还必须补充\usepackage{amsmath, amssymb}一点。main.tex

也就是说，它看起来import不喜欢文件名中的空格，如果我将文件重命名fig1.2.1.tex并进行main.tex相应的更改，它似乎可以正常工作。
