Hey Cory Thanks for the tip with the array [(0,0,0) .... (0,0,0), (x,y,time),(0,0,0)...(0,0,0)] While this was easy to do, I still get a point in Paraview at 0/0 for each time, or, if I choose to draw a line, one that starts at 0/0 - which is kind of understandable, when looking at my table, which is 0 everywhere but on one point. Can you give me another hint on how to proceed? I only want PV to draw ONE point at (x,y)...
