Ok. Let me rephrase my question. Maybe someone speaks Matlab? Full Matlab Code below (see [1]).
Let's assume I have a 2x2 matrix with color values C=[1 2; 3 4]. Now I can visualize this matrix with on a 2x2 grid with surf in Matlab. What I get is one square with the color values on each node (see Case 1 in the Matlab code). This is what Paraview does! What I want is the following: I define a new grid, which is 3x3. So one value more in each direction than I have color values. On this grid the color values live cell-centered. If I now visualize this in Matlab, I get a 2x2 block matrix with color values from 1-4. This is what I want! To sum up: I want to keep my color values, but I want to define a new cell-centered grid (with size(C,1)+1) where these color values live on. Is this somehow possible in Paraview? Thank you! Henrik [1] % Full Matlab Code to visualize the two cases.

Januar 2018 21:13 An: paraview@paraview.org Betreff: [Paraview] Visualize equdistant cell-centered data Dear all, I have a "Structured (Curvilinear) Grid" (*.vts), which gets read in as 314531 cells and 330000 points. I would like to tell Paraview that this is equidistant cell-centered data (330000 cells). I want every cell to get one color, such that color interpolation becomes correct. Can I somehow convert the data I have? Thank you! Henrik Büsing
