Select Columns in the JMP Columns Viewer

The Columns Viewer option in the Cols menu helps you quickly select columns by attributes, properties, and statistics, particularly in a data table that has many columns. You can view summary statistics and properties for those columns, view quartiles in the summary statistics, subset the data, and more. And columns in the Columns Viewer window are also linked to the data table columns.

The Columns Viewer gives you a quick view of data table characteristics. For example, the Summary Statistics report shows which columns contain missing values. You can select those columns in the report and then exclude them in the data table.

Figure 4.12 Identify Missing Values 

Identify Missing Values

The Summary Statistics report shows the following information:

the total number of rows (N)

the number of rows with missing values (N Missing)

the number of categories (N Categories)

for continuous data, the Min, Max, Mean, and Std Dev

Other options include the following:

Clear Select

Deselects columns in the data table and in the Columns Viewer. This option ensures that no columns are selected before you begin selecting columns.


Creates a linked subset data table from the selected columns.

Show Summary

Creates a linked Summary Statistics report for the selected columns. Right-click to select options such as sorting by column or creating a data table. Select Show Quartiles to include lower quartiles, upper quartiles, and interquartile ranges. To create a linked data table from all columns in the report, click the Summary Statistics red triangle and select Data Table View.

Find Columns with Properties

Shows a list of column properties in the Columns with Properties report. Select the properties that you want to find and then click OK to create a linked report from all columns. Or you can select columns first in the Select Columns list and then show the list of properties just for those columns.


Each time you click the Show Summary or Find Columns with Properties buttons, a new report is added to the window. To delete a report, select Remove from the report’s red triangle menu.

Deleting rows from a data table view created from Columns Viewer is not undo-able.

2. Select Cols > Columns Viewer to open the Data Table Columns Viewer window.

3. Select Find Columns with Properties, select Formula, and click OK.
