Histogram Frequency Scale
This is the scale used to plot the Histogram bars. This scale shows either the number of observations in each plotted bar or the relative frequencies per bar (an option on the View menu).
This is the X-Axis scale used to plot the Histogram.
Histogram Interval Size Selection
An optional Interval size may be entered into this box. Entering a value of zero generates a Histogram using the default interval size.
This displays the Histogram or Frequency Plot. A superimposed normal curve is optional.
The title will be added here above the word Histogram. This title may be edited.
Variables may be selected from this list for display in the chart. Clicking an item on this list will redraw the chart.
Histogram Constant X-Axis
Checking this Checkbox will fix the X-Axis so multiple groups can be checked using the same scale.
Histogram First Interval Midpoint
The first interval used may be set here. If greater than the smallest value, a smaller value will be used that is a multiple of the interval size selected and which will generate an interval midpoint of the selected value.
