Hi,

I am new on Paraview. I have VTK file format and I would like to show the temperature gradient in paraview. However, I do not now to how operated. I saw some examples on Youtyob but it did not give me what I am looking for.

The file is describing the temperature of a tip needle going through the object. So, how I could represent that in Paraview?

the file consists with:

- cell id information
- cell type
- temperature gradient data (x,y,z)

This question seems to be on the basic operation of ParaView. I suggest you take some time to go over some of the early exercises in the ParaView tutorial (which you can download by going to the `Help` menu and selecting `ParaView Tutorial`).

If you want a more specific answer, I think we need a more specific question. So, you open the .vtk file, `Apply` it, and then color it by the temperature gradient. What do you see? And what do you want to see?
