2D colour map from .csv

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 (3.1 MB).

I have followed the instructions from here 2D contour from .csv 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 (5.9 KB) from the topic of the referenced post.

I am using Paraview 6.0.1. in Linux.

Many thanks in advance,

Katie
