Gnuplot以不同颜色覆盖透明3D表面和平面
我想画一个和这个相似的数字 在gnuplot中。因此,在曲面上有一条线穿过略微透明的平面。点不是很重要。对于我的工作流程,我使用gnuplottex。到目前为止,我在这里: 这是我的密码Gnuplot以不同颜色覆盖透明3D表面和平面,3d,gnuplot,transparency,latex-environment,3d,Gnuplot,Transparency,Latex Environment,我想画一个和这个相似的数字 在gnuplot中。因此,在曲面上有一条线穿过略微透明的平面。点不是很重要。对于我的工作流程,我使用gnuplottex。到目前为止,我在这里: 这是我的密码 \documentclass{standalone} \newif\ifwindows \IfFileExists{/dev/null}{\windowsfalse}{\windowstrue} \ifwindows \usepackage[miktex,cleanup]{gnuplottex} \els

我尝试了ps和pdf输出的pslatex
和cairolatex
终端。问题是,我希望将网格从平面中移除,并以单调(或至少不同)的颜色着色。网格可以通过nosurface
删除,但我仍然可以看到一个各种颜色的平面。
PS:我知道PS的透明度不太好,但在本例中,带有
pslatex
终端的表面实际上工作得很好。使用多点打印完成了以下操作:
