title: Merge PointData from multiple files in Paraview
body: <p>I am tasked with combining multiple files in Paraview for a representation.
  To be precise, I have a .vtk file that defines the whole mesh structure, which works fine. I have a second file (text-based, e.g. csv) with a single value per line, where each line is a PointData value, i.e.:</p>
  
  <pre><code>[PointData[0]]
  [PointData[1]]
  [PointData[2]]
  [...]
  [PointData[n-1]]
  </code></pre>
  
  <p>I tried playing around with programmable sources and filters, but couldn't get it to work. I would appreciate your help. I hope the description was clear, but I added a picture of the setup to clarify the situation.</p>
