从 geogebra 导出图形

Question

我在 geogebra 中绘制了以下内容：

我尝试将其导出到 latex，它会生成以下代码

但它会产生：

我不太清楚我做错了什么？

Answer 1

显然，geogebra 不知道如何正确导出到tikz。无论如何，您都应该向 geogebra 提交错误报告。

\fill正如 Loop Space 所写，您应该用替换第一个命令\draw。这还不够，输出非常丑陋。作为第一个修复，您可以尝试减小字体大小，这样标签就不会互相接触（font=\scriptsize下面的选项）。此外，这两个标签“消耗”并且$\lambda \gamma^*_\pi(t)$非常接近。这真的应该是一个还是两个标签？也许您可以在 geogebra 文件中修复这个问题。下面，我决定合并这两个标签并将它们对齐anchor=north（否west）。我不确定这是否是您想要的。

根据您要转换为 LaTeX 的图像数量，您可能需要更精确地了解如何使用 放置标签tikz。否则，您只需使用标签的精确坐标即可。
