我在用着文字图创建图形和其他东西，有点懒，不想编写所有内容。我选择将代码导出tikz 到 以便使用tikzpicture。如果我不需要缩放任何东西，结果会很棒，但是当涉及到缩放时，事情就不那么好了。
我尝试了内置的缩放选项tikzpicture，但这不会缩放文本，因此显示效果不正确。然后我尝试使用命令\pgftransformscale，这让情况有所改善，但它只给了我想要的效果，就与一起使用时的缩放而言\pgflowlevel。但是位置不对，我不知道如何移动它。这里有一个简短的例子来说明我的意思。第一个是原始大小，第二个是较小的大小，比例因子为原来的一半

我想知道是否有办法移动渲染的对象，或者是否有另一种可以自行完成缩放的方法。
答案1
稍微改变一下比例，你就能得到一张合适的图片。因此，用下面的代码更改缩放图片的初始行。
\begin{tikzpicture}[baseline=(current bounding box.center),transform canvas={scale around={0.5:(5,-5)}}]% <- Changed
但我认为懒惰不是一个有效的借口，因为你已经体验过无法控制最终的图片，因此需要付出更多努力。事实上，通过以下方法做到这一点非常简单pgfplots
\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\noindent Soit le graphique suivant:
\begin{tikzpicture}[mydot/.style={blue,inner sep=1pt,fill,circle}]
\begin{axis}[no marks,
xmin=-5,xmax=5,
ymin=-5,ymax=5,
grid=both,
axis lines=middle,
axis line style={-|},
xtick={-5,...,5},
ytick={-5,...,5},
minor tick num=1,
x=1cm,y=1cm
]
\addplot {x+2};
\addplot {1.5*x+1};
\addplot {-x-4};
\node[mydot] at (axis cs:0,1) {};
\node[mydot] at (axis cs:0,2) {};
\node[mydot] at (axis cs:0,-4) {};
\end{axis}
\end{tikzpicture}
\end{document}
