[Paraview] pvti example with data in cells question

[Nikolay Khokhlov]

 Hello,

I'm trying to use pvti format to save data.
I've create example with 8 cells, but I've got different view when open files *.vti and file pvti separately (image attached).
What could be the problem?


File x.pvti:
<?xml version="1.0"?>
<VTKFile type="PImageData" version="0.1">
  <PImageData WholeExtent="0 4 0 2 0 0" Origin="0.000000 1.000000 0.000000" Spacing="0.100000 0.100000 0.000000" GhostLevel="0">
    <Piece Extent="0 2 0 2 0 0" Source="./1.vti"/>
    <Piece Extent="2 4 0 2 0 0" Source="./2.vti"/>
      <PCellData Scalars = "vx" >
          <PDataArray type="Float32" Name="vx" />
      </PCellData>
  </PImageData>
</VTKFile>

File 1.vti:
<?xml version="1.0"?>
<VTKFile type="ImageData" version="0.1">
  <ImageData WholeExtent="0 2 0 2 0 0" Origin="0.000000 1.000000 0.000000" Spacing="0.100000 0.100000 0.000000">
    <Piece Extent="0 2 0 2 0 0">
      <CellData Scalars = "vx" >
        <DataArray type="Float32" Name="vx" format="ascii">
            1 2 3 4
        </DataArray>
      </CellData>
    </Piece>
  </ImageData>
</VTKFile>

File 2.vti:
<?xml version="1.0"?>
<VTKFile type="ImageData" version="0.1">
  <ImageData WholeExtent="0 2 0 2 0 0" Origin="0.200000 1.000000 0.000000" Spacing="0.100000 0.100000 0.000000">
    <Piece Extent="0 2 0 2 0 0">
      <CellData Scalars = "vx" >
        <DataArray type="Float32" Name="vx" format="ascii">
             5 6 7 8
        </DataArray>
      </CellData>
    </Piece>
  </ImageData>
</VTKFile>
