I have large data set arranged in four column in a file like this
# X Y Z f
0 0 0 0
1 0 0 0
2 0 0 0
3 0 0 0
4 0 0 0
5 0 0 0
6 0 0 0
7 0 0 0
...
where (x,y,z)
is coordinate of each point in 3D mesh (between [0,1]
in each direction and each direction divided into 256 interval) and f
is the value of field at each point. I want to plot the data in a way that at each point, a colored circle, its color specified according to the value of f
plotted. Since it is very large data set, the solution provided in link does not work properly, and I have incorrect plot like this
# X Y Z f
is not exist in the file.I only added to make it clear which column correspond to which variable. – Pejvak(0,0,0)
looks ok. But if I don't have the data I cannot tell whether it is correct or not. So, you want to say that z should also be within[0,1]
? Could you please describe exactly what you think is incorrect? – theozh(x,y,z)
I want to plot small circle colored byf
value. I do not know if it is possible in gnuplot. – Pejvak
