问题描述
我有一个函数依赖于phi和theta，我想在一个球体的表面上绘图。
日期存储在一个带有列的.txt文件中：
I have a function dependent on phi and theta, which I want to plot on the surface of a sphere.The date is stored in a .txt file with the columns:
1: x = R*sin(theta)*cos(phi)
2: y = R*sin(theta)*sin(phi)
3: z = R*cos(theta)
4: density
我使用以下gnuplot代码来绘制：
I use the following gnuplot code to plot:
set terminal wxt size 800,800
set mapping cartesian
set view equal xyz
set xlabel 'x'
set ylabel 'y'
set zlabel 'z'
splot "densityprofile_100.000.txt" u 1:2:3:4 with pm3d
pause -1
不幸的是，Gnuplot似乎无法正确表示球体上的颜色。似乎有一些影子，我无法摆脱;看到图片在这里：
Unfortunately Gnuplot doesn't seem to be able to properly represent the colours on the sphere. There seems to be some shadow, which I can not get rid off; see the picture here:
当我用鼠标转动球体时，阴影变得越来越小，但没有完全消失的位置。
提供任何帮助。
When I turn the sphere with my mouse, the shadow gets smaller and bigger, but there is no position in which it fully disappears.Any help is appreciated.
推荐答案
通过添加以下行，找到了解决我的问题的方法：
I found the solution to my problem by adding the following line:
set pm3d depthorder
