This may be caused by incorrectly set Peak Width parameter (PW). Peak Width parameter affects two things:
- Peak detection algorithm, i.e. what will be considered as a peak, peak start and peak end position.
- Sample bunching, i.e. how many samples will be summarized as one data point. It can be imagined as a very simple signal filter which makes the signal smoother. The formula is that approximately 30 data points is necessary for peak detection. So for instance if you set PW=1 min and Sampling rate is 100 Hz, each series of 200 points will be displayed as one point (60*100/30). Default value (0,1 min) corresponds to sample rates around 10 Hz, for higher sample rates it should be decreased.
As a remedy check the Peak Width parameters in Method Setup dialog.
