addplot3[surf] 创建线而不是表面

Question

我一直在尝试创建表面图，但无法使其工作。任何帮助都将不胜感激。我尝试使用，surf它只会生成线条而不是表面（图 1）。注意：虽然我最初能够生成输出，但该surf图不再编译：“Package tikz Error”。我尝试使用带有 -shell-escape 标志的 pdflatex 和 lualatex 进行编译。

图1

我也尝试使用patch样式图。这会产生乱码（图 2）

太感谢了。

Answer 1

PGFPlots 需要知道每行数据中有多少个坐标。使用您当前使用的格式，它无法推断此信息，因为它只能看到一行长坐标（换行符不足以中断序列）。

为了使情节正确运作，你可以

• 放mesh/cols=13
• 放mesh/rows=13
• 在第一行数据后添加一个空行
