The range of voltage levels measured from the waveform selected by the "Amplitude W.F. #" is divided evenly into a number of bins. Each bin counts the number of action potentials, on the waveform selected by the "Spike W.F. #", occurring when the level on the first waveform is in the range of this bin. The resulting graph shows the average number of action potentials at each waveform level sub-range.
The parameters "W.F. amplitude delay" and "W.F. amplitude window" indicate a range of points, relative to the point where the action potential occurred, used to obtain a level reading on the waveform selected by the "Amplitude W.F. #". The range of voltage levels can be restricted to a smaller range, by setting the parameters "Min W.F. amplitude" and "Max W.F. amplitude". Only action potentials whose associated waveform level readings stay within these bounds will be included in the histogram.
