我有几条由一些点确定的曲线。我需要绘制它们确定的表面。也就是说，我有这个

但我需要这个
我该怎么办？谢谢。
答案1
在第一个例子中，我将代码缩减为仅前五行数据，相反，在第二个例子中，我将数据增加了一倍。
我切换到 3D 图形类型（surf）并开始查阅 pgfplots 手册http://mirrors.ctan.org/graphics/pgf/contrib/pgfplots/doc/pgfplots.pdf。关键开关是mesh/rows=3。您可以在下图中看到改进（从左图到中间图）。然后我想出了一个有趣的选项faceted color=green，但它对我们没有帮助，因为我们只需要在一个方向上绘制线条，请参见下图右侧。也许这是 Feuersänger 博士及其同事的潜在功能。因为在这种特殊情况下，我们需要x faceted color和y faceted color。
我附上一个例子，关键行是第 9 行，我正在更改它。我在行首，在 之前放了一个百分号faceted，而不是什么都没有。
\documentclass{article}
\pagestyle{empty}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[width=12cm, height=12cm,
xmin=0,view={40}{10},]
\addplot3 [surf,
mesh/rows=3, faceted color=green, line width=2pt,
]
table {
1 0 -5.5829
1 5.0000 1.3534
1 10.0000 7.7874
1 15.0000 13.7943
1 20.0000 19.4479
2 0 -5.3375
2 5.0000 1.5442
2 10.0000 7.9298
2 15.0000 13.8943
2 20.0000 19.5114
3 0 -6.0748
3 5.0000 0.9575
3 10.0000 7.4763
3 15.0000 13.5574
3 20.0000 19.2753
};
\end{axis}
\end{tikzpicture}
\end{document}
然后就到了使用分层图表的正确时机。绘制图表后，surf我们只需要在上面放置（折线）线。作为绘图奖励，我激活了该shader选项。此绘图策略说明了下一个源代码和图形预览。唯一的缺点是我需要重新排列您的数据并将其加倍。我相信我们可以以某种方式对其进行优化，但我将保留图表原样以进行进一步改进。
