(x,y) 值定义非结构化网格。结果我不得不使用

set dgrid3d

通过插值来构建规则网格，因为 gnuplot 暂时不执行三角测量。 数据波动很大，良好的分辨率需要使用非常密集的网格。我尝试过

set dgrid3d 512,512

和

set dgrid3d 900,900

并使用 pm3d 绘制文件，请参见下文。在后一种情况下，分辨率更好，但正如您所看到的，仍然存在颜色跳跃：有没有办法使颜色沿整个绘图平滑变化？（仅在振荡较慢的区域，颜色确实会变化）顺利）。我还使用

set contour

将 3D 绘图投影到 (x,y) 平面，然后使用

set cntrparam levels

将 1000 个轮廓投影到 (x,y) 平面上，以获得更好的分辨率，以及

set palette maxcolors 1024

但这不会改变任何东西。如果有人能给我提示...

512x512 点网格与 dgrid3d

900x900 点网格与 dgrid3d

Answer 1

我真的不明白 Delaunay 三角测量在这种情况下有什么帮助。 dgrid3d 的高斯内核似乎是更好的选择。但无论如何，您可以在 gnuplot 6 中进行三角测量。这种模式目前尚未记录，因为实现仅按照需要完成，作为生成凹壳的一个步骤。 绘图样式

with polygons

从三角形的第一个顶点获取颜色。更完整的实现可以允许其他选项，例如平均顶点 z 值。

set style fill solid border lc "black"
plot 'DATA' using 1:2:3 delaunay with polygons lc palette
