Oh dear! I wrote a little too soon Alex, sorry. The trace looks OK at first and then I realised that it had more plotted points that the number of data samples (twice as many). These are positioned at the integer points of samples on the X axis and also erroneously at 1/3 of the distance between these points. (So at X = 1, 1.33, 2 etc..) I cannot see where these points come from , any ideas?
