How to correctly define dimensions for 1D structured points legacy vtk format?

Question

I am just in the beginnings of learning how to make vtk files. I was trying to start really simple and just made a 1D structured points vtk file. Below is an extremely simple attempt:

# vtk DataFile Version 2.0
Vis Project Data
ASCII
DATASET STRUCTURED_POINTS
DIMENSIONS 2 1 1
ORIGIN 0 0 0
SPACING 1 1 1
POINT_DATA 2
SCALARS phi float 1
LOOKUP_TABLE default
0.1
0.2

However, whenever I try to load in the file on paraview I get the error "Incorrect Dimensionality"

This is probably a really stupid question but I will be forever grateful for an answer.

Thanks!
