On a 32-bit system the limitation on number of points is roughly 8 million. On a 64-bit system there is effectively no limit. > Or do I need to use different command?? You said the command does work for 500 points, right? I can think of two possible problems. 1) There is a single bad line (only 2 coordinates readable instead of 3 coordinates x/y/z). In this case you may be able to force the correct interpretation by saying instead splot "PARTICLE_TRACK_000" using 1:2:3 with lines 2) The input stream is truncated due to some buffer size limitation in Windows. That seems unlikely to me, but perhaps someone more familiar with Windows configuration can help. > > Mat M Tamimi > mtamimi@netzero.net
