我所有函数的最后一部分都丢失了。我在这里找到了一些类似的帖子，建议更改域/样本。我尝试了许多不同的样本值，最多 10000 个，但没有一个能解决问题或导致内存错误。有什么想法可以解决这个问题吗？

按照以下方式更改代码的相应行：
samples=1000,
axis y line=center,
axis x line=middle,
]
\draw (7,8.5) node[anchor=north west] {$h$};
\addplot+[mark=none, domain=0:17,color=black] {(17^3-x^3)^(1/3)};
\addplot+[mark=none, domain=0:16, color=black] {(16^3-x^3)^(1/3)};
\addplot+[mark=none, domain=0:15, color=black] {(15^3-x^3)^(1/3)};
\addplot+[mark=none, domain=0:14,color=black] {(14^3-x^3)^(1/3)};
\addplot+[mark=none, domain=0:13,color=black] {(13^3-x^3)^(1/3)};
现在的输出是：
