Hi, That indeed solved my problem. Thanks!

Hey Luis, You need to specify not only points, but some types of cells (with connectivity information) in your VTP file. If you want just disconnected vertices, here is an example: <VTKFile type="PolyData" version="0.1" byte_order="LittleEndian"> <PolyData> <Piece NumberOfPoints="6" NumberOfVerts="6"> <PointData Scalars="Elevation"> <DataArray type="Float32" Name="Elevation" format="ascii" RangeMin="0.08345169574" RangeMax="0.6968934536"> 0.58468127251 0.08345169574 0.18121850491 0.42782235146 0.63408386707 0.6968934536 </DataArray> </PointData> <CellData> </CellData> <Points> <DataArray type="Float32" Name="Points" NumberOfComponents="3" format="ascii" RangeMin="0.57506519638" RangeMax="1.9611330035"> -0.20559799671 0.2926761806 1.837474823 -0.13291372359 -0.59396106005 -0.53818535805 -0.54464870691 -0.11054357141 0.14777646959 -0.59555768967 0.78732067347 1.0635436773 0.6602383852 -0.33984100819 1.6050319672 1.8132208586 0.72800821066 0.16815713048 </DataArray> </Points> <Verts> <DataArray type="Int32" Name="connectivity" format="ascii" RangeMin="0" RangeMax="5"> 0 1 2 3 4 5 </DataArray> <DataArray type="Int32" Name="offsets" format="ascii" RangeMin="1" RangeMax="6"> 1 2 3 4 5 6 </DataArray> </Verts> </Piece> </PolyData> </VTKFile> A good way to test the file formats is to create the type of data you want with ParaView Sources and then Save As the data format you want to use. (Here I created a Point Source, followed by the Tetrahedralize filter to create an Unstructured Grid with each point being its own cell, and then an Extract Surface filter to turn it back into PolyData. I just ran the Elevation filter to create a scalar attribute.)

If I show the legend, the max and min values are correct. If I show the values as labels, they are correct. What I would like to know is how I can get the points to show the right color. BTW, Paraview crashes if I change the file to only use 2 components.....
