Dear, could someone help me please?
I have a file with 4 column.
I would like plot a graphic 4D, where the axis x, y and z are the column from 1 to 3, respectively, and the color code is the column 4.
I built a graphic, is attached, but I would like make a surface. I read it is possible using mesh comand. But I could not.
Thank you advanced

Hi,
As per my understanding you are able to create a 3-D plot. However, you need guidance in representating an additional column of data using color codes. The above requirement can be sovled using 'mesh' or 'surf' command (for creating mesh or surface plot).
The following example could help you with your requirement:
[X,Y] = meshgrid(-8:.5:8);
Z = sin(X) + cos(Y);
C = X.*Y;
mesh(X,Y,Z,C);
or
[X,Y] = meshgrid(-8:.5:8);
Z = sin(X) + cos(Y);
C = X.*Y;
surf(X,Y,Z,C);
