Update: appears to be a problem with paraview 5.5.1 on MacOS. The code for the vector IO had been working previously, but I made some changes and thought I’d broken it, and wanted to pose the question w/o the overhead of “this used to work”.
On my desktop I have an old version of paraview, 5.3 RC3. However, it correctly displays the vectors, and allows for me to color them, etc.
The version of PV on my laptop is 5.5.1, and it does not correctly display the vectors nor allows for me to colour them.
I’ve attached two images to show what I mean.
works
