答案1

通常情况下，调整您设置为 的比例因子scale=2.00即可完成工作。但是在这种情况下，您有固定最小大小的节点，还有文本。因此在这种情况下您可以使用。以下是您的图形在比例因子为时scalebox的样子0.75：0.50

enter image description here

不幸的是，这种方法也会缩放文本。我不确定是否有一种简单的自动化方法来调整这个数字，而无需返回到最初用于生成它的软件。

我认为直接用 来画一个图形并不难tikz，但需要一定的学习时间。如果你要画很多不同的图形，我建议你先学习一下，tikz这样你就能更好地控制图形了。

笔记：

  • 使用此方法，您需要将 放置scalebox{}{}在浮动环境中，而不是tikzpicture。

我能想到的唯一其他选择是根据比例因子调整圆圈minimum size，但由于信息太多，输出会变得混乱：

\pgfmathsetmacro{\MinSize}{3*\Scale/2}
\node [draw, thick, minimum size=\MinSize cm, circle, red] at (0.5,1.3) {};
\node [draw, thick, minimum size=\MinSize cm, circle, blue] at (0.0,0) {};
\node [draw, thick, minimum size=\MinSize cm, circle, brown] at (1,0) {};
\node [draw, dotted, minimum size=\MinSize cm, circle, magenta] at (2.2,0.25) {};
\node [draw, dotted, minimum size=\MinSize cm, circle, violet] at (1.65,1.05) {};
\node [draw, dotted, minimum size=\MinSize cm, circle, green] at (1.45,2.15) {};

以下是从 2.00 更改为 1.5 和 1.0 后的输出scale（添加了颜色，以便我可以使用代码跟踪输出）：

enter image description here

正如您所见，该图相当混乱，因此无法通过这种方式获得太大的缩放比例。

代码：使用\scalebox缩放：
