Select Regular from the Graphs - Graphs of Input Data - Histogram menu to create a histogram of the values of the currently highlighted variable without a normal fit to the data. If the selected variable is categorical (usually 10 or less categories), then STATISTICA will use those categories as the histogram intervals. If the variable has either more than 10 categories or the values are non-integers (continuous), then STATISTICA will divide the values into about 10 to 12 intervals based on the range of the values. These intervals are then used in the histogram.
