- Hi, I got a trivial question about 3-D plot. I have a datafile as follows:
-
- # x y z
- 10.0 1.0 90
- 10.0 1.5 100
- 10.0 2.0 90
- 12.5 1.0 90
- 12.5 1.5 100
- 12.5 2.0 90
- 15.0 1.0 90
- 15.0 1.5 100
- 15.0 2.0 90
-
- What I want to draw is a 3-d surface with grid lines. The gnuplot command I
- typed were: set term x11
- set parametric
- splot "datafile" w linesp
- Instead, I got a plot in which each two consecutive data points are connected
- by a line. It is not a good display at all. Is there some way to get the grid
- surface or I missed something?
- I appreciate your help.
