Thanks Magician, I have been using that workaround so far but it was annoying. At moment I am adding a new scalar in the file containing the localID.
Best regards , Luigi -------- Messaggio originale -------- Oggetto: Re: [Paraview] [EXTERNAL] Unable to rescale properly the color map Da: Magician A: [email protected] CC: ParaView Hi Luigi, I have the same problem when I display color contours with UNIX Timestamps. The instant solution is using Calculator filter. Subtract 1600000 from CellIDs, you may get correct results. # Of course I want to be fixed the problem about the precision of contour ranges, too.
