THE HISTOGRAM WINDOW
The HISTOGRAM window is used to display the number of times each code occurred in a low amplitude
signal. The user can select which channel is to be displayed as a histogram by using the option buttons and then
pressing the "Histogram" button. In order to keep the execution time as short as possible the histogram routine
first checks to see if the span of codes (i.e. the Max code - the Min code) is less than 1500. If the span is greater
than this the program will display an error message and will not perform the histogram operation.
The Histogram window is shown in Fig. 6 below.
