HISTOGRAM
The Histogram allows the user to observe the data taken from a conversion and deter-
mine the relative variation of the digital codes. The histogram plot shows the digital 
codes on the X-Axis and the number of occurrences for each code on the Y-Axis. The 
statical values of the data set are shown at the bottom of the window. The Span Control 
locks in the number of codes shown on the X-Axis or allows the program to 
automatically scale the axis for every conversion.
