Options for Categorical Variables

The red triangle menus next to each variable in the report window contain additional options that apply to the variable. This section describes the options that are available for categorical (nominal or ordinal) variables.

To see the options that are available for continuous variables, see Options for Continuous Variables.

Description of Options for Categorical Variables
The Display Options sub-menu contains the following options:
Frequencies	Shows or hides the Frequencies report. See The Frequencies Report.
Horizontal Layout	Changes the orientation of the histogram and the reports to vertical or horizontal.
Axes on Left	Moves the Count, Prob, and Density axes to the left instead of the right. This option is applicable only if Horizontal Layout is selected.
The Histogram Options sub-menu contains the following options:
Histogram	Shows or hides the histogram. See Histograms.
Vertical	Changes the orientation of the histogram from a vertical to a horizontal orientation.
Std Error Bars	Draws the standard error bar on each level of the histogram.
Separate Bars	Separates the histogram bars.
Histogram Color	Changes the color of the histogram bars.
Count Axis	Adds an axis that shows the frequency of column values represented by the histogram bars.
Prob Axis	Adds an axis that shows the proportion of column values represented by histogram bars.
Density Axis	Adds an axis that shows the length of the bars in the histogram. The count and probability axes are based on the following calculations: prob = (bar width)density count = (bar width)density*(total count)
Show Percents	Labels the percent of column values represented by each histogram bar.
Show Counts	Labels the frequency of column values represented by each histogram bar.

Mosaic Plot	Displays a mosaic bar chart for each nominal or ordinal response variable. A mosaic plot is a stacked bar chart where each segment is proportional to its group’s frequency count.
Order By	Reorders the histogram, mosaic plot, and Frequencies report in ascending or descending order, by count. To save the new order as a column property, use the Save > Value Ordering option.
Test Probabilities	Displays a report that tests hypothesized probabilities. See Examples of the Test Probabilities Option for more details.
Confidence Interval	This menu contains confidence levels. Select a value that is listed, or select Other to enter your own. JMP computes score confidence intervals.
The Save sub-menu contains the following options:
Level Numbers	Creates a new column in the data table called Level <colname>. The level number of each observation corresponds to the histogram bar that contains the observation.
Value Ordering	(Use with the Order By option) Creates a new value ordering column property in the data table, reflecting the new order.
Script to log	Displays the script commands to generate the current report in the log window. Select View > Log to see the log window.

Remove	Permanently removes the variable and all its reports from the Distribution report.
