生成图片

我正在尝试使用 Tikz 代码生成在 Geogebra 上创建的图片。 在此处输入图片描述

这张图片是我在玩一些函数时幸运得到的。现在，我使用以下代码在 Tikz 上生成图片，但它没有编译坐标。也许是其他原因导致它没有编译，我看不出来。

\begin{scriptsize}

\end{scriptsize}
\end{tikzpicture}

有什么建议么？

顺便问一下，我们如何在 Tikz 中创建随机函数（图形）？谢谢！

答案1

绘制一个简化的尝试作为建议，并调试和添加 Geogebra 输出。对于后者，draw plot和dash pattern=on 1pt off 1pt是错误的主要来源。

起点如何绘制随机函数在这儿。
