我正在使用 matlab2tikz 为我的图形生成 tikz 代码。当使用下面的图形代码编译文档时，我收到错误：
Package pgfplots Error: No such element: \pgfplotsarrayselect64\of{pgfpl@cm@mymap}
现在真正让我感到困惑的是，当我用另一个数据集生成相同的图形时，它工作得很好！据我所知，除了包含的数据点外，实际的 tikz 代码是相同的。第二个数据集图形中的什么原因导致它在编译时失败？
我更新了 Mixtex 中的所有软件包，但似乎没什么用。如果您能告诉我我做错了什么，我将不胜感激，因为我越来越急切地想找到问题所在。

答案1
这只是颜色图定义中的一个错误。
colormap={mymap}{[1pt] rgb(0pt)=(0,1,1); rgb(63pt)=(1,0,1)},
尝试用以下方法修复它：
colormap ={mymap}{rgb(0pt)=(0,1,1); rgb(63pt)=(1,0,1)},
