Hi all,
What I am trying to is hopefully (!) very very simple, but I am still struggling to find a solution. I am trying to plot a colour map from a csv file containing columns x, y, z. I would like to have a 2D plot coloured by the z coordinate. There are a lot of zeros in the z coordinate, but there are some non-zero values. Here is the file [eta\_road\_9.csv](https://discourse.paraview.org/uploads/short-url/KEnYggmPHpkuXMcOCXsQDiW9Xu.csv) (3.1 MB).
I have followed the instructions from here [2D contour from .csv](https://discourse.paraview.org/t/2d-contour-from-csv/2913) and done
Upload file → Apply
Table to Points → X Column=x\_coords, Y Column=y\_coords, Z Column=height→ Tick 2D Points → Apply
Delaunay2D → Apply
The issue is that in the Delaunay2D filter there is no option to colour by “height“, the only option is Solid Colour”. The same issue also happens when I try to plot the data [data-to-contour.csv](https://discourse.paraview.org/uploads/short-url/r0HTbrOVaCxmk18WonXK8yESJXU.csv) (5.9 KB) from the topic of the referenced post.
I am using Paraview 6.0.1. in Linux.
Many thanks in advance,
Katie
