- First of all, thanks to the developers of gnuplot for a fine program.
- I've been using it for labs and instruction in the senior undergraduate
- climatology course that I teach.
-
- I would like to use splot to contour and draw a surface of gridded
- data read from a file. Is this possible? All I can do so far is plot
- the actual data points. Here is what I do:
-
- set parametric
- set surface
- splot "test.data"
-
- which plots the data points, but no surface connecting them.
-
- when I "set contour" there is an error message: "Can not contour non
- grid data!" even though the data is defined on a regular grid. I have
- no difficulty with surface plots of functions. I'm using gnuplot 3.2
- on unix DECstations.
