Process Description

Data Filter

The Data Filter command is a JMP process that gives you a variety of ways to select, hide, or exclude subsets of data from plots and analyses. It is surfaced in many JMP Genomics reports.

Main Controls

The main controls in the Data Filter include the following:

Clear: Clears all selections that you have made on variables in the Data Filter window.

Start Over: Closes the current Data Filter session and returns you to the original Data Filter window.

Favorites: Saves your current data filter criteria as a favorite. Once you have created a favorite, selecting it resets the current conditions to the criteria in the favorite. You can also remove the favorite. To retain favorites once the current session ends, save the data filter script by selecting one of the Script options from the Data Filter red triangle menu.

Select: Click the check box to show the selected rows in the data table in a highlighted state.

Show: Shows the unselected rows with the Hide icon.

Include: Shows the unselected rows with the Exclude icon.

Note: There are two additional options when filtering: Auto clear and Conditional. These options are available from the red triangle menu for the Data Filter.

Inverse: Click the check box to invert the current selection state of the rows in the data table.

Note: Only the rows in the data table are inverted, not the selection in the Data Filter. To invert the selection in the Data Filter, from the column’s red triangle menu, select Invert Selection.

AND: Opens the Add Filter Columns list. The and operator restricts the selection. You can add variables to the filter process at any time.

OR: Opens the OR Add Filter Columns list. The or operator extends the selection. You can add variables to the filter process at any time.

Changing the Row State in the Data Table After Making Data Filter Selections

If you modify a row state that you have set in the Data Filter and subsequently alter row states in the data table, or select points in a graph or plot, the selections in the Data Filter might not match the selections in the data table. The Data Filter contains a warning message that says: Your selection was changed in another window. The Reset Selection button appears. Clicking Reset Selection changes the data table selections back to reflect the selections in the Data Filter.

Red Triangle Options for the Data Filter

The red triangle menu next to Data Filter contains the following options:

Auto clear:

If you have more than one nominal or ordinal column selected in the Data Filter, this option clears any other selections before making a new selection.

Conditional:

Limits the categories displayed for the unselected filter column. For filter columns with hierarchy, you can use the Conditional option to filter what appears in the column lists.

Use Floating Window:

Keeps the Data Filter window on top of its associated data table. If you do not want the Data Filter window to remain on top, deselect this option.

Animation:

The animation feature sequentially highlights the values of a single variable. The variable’s values highlight in the data table. However, patterns are more interesting if you first create a plot and then animate a variable using the Data Filter to see how it behaves on the plot.

To use the animation feature, from the red triangle menu next to Data Filter, select Animation. Then select the variable that you want to animate. The highlighted frame around the variable indicates which variable is selected for animation

The Animation Controls panel (shown above) is surfaced when you select Animation. It contains the following controls:

The middle button starts and stops the animation. After you start the animation cycles, the button changes to a stop button (). By default the animation begins with the first value of the topmost variable.

The backward arrow moves the animation backward one cycle. Click more than once to go backward more than one cycle.

The forward arrow moves the animation forward one cycle. Click more than once to go forward more than one cycle.

The square button hides the Animation Controls panel on the Data Filter Window. Select Animation from the menu on the Data Filter title bar again to see the Animation Controls.

Use the slider to adjust the speed of the animation (slower to faster).

The drop-down menu contains the following options:

Forward: Highlights values from first to last.

Backward: Highlights values from last to first.

Bounce: Highlights forward and then backward repeatedly.

Show Subset: Creates a new data table that contains only the following:

The rows identified by the Data Filter.

The columns selected in the active data table. If no columns are selected, then all columns are included.

Save WHERE Clause:

Once you have filtered variable values in the Data Filter, that information can be expressed as a JMP WHERE clause that is to identify specific rows of data for processing or analysis. The Data Filter builds a WHERE clause based on the value selections that you make.

The options in the Save WHERE Clause menu include the following:

to Clipboard: Creates a WHERE clause from the filter criteria and puts it on the clipboard.

to Row State Column: Creates a row state column in the data table that has a formula equivalent to the filter criteria.

to Data Table: Creates a WHERE clause from the filter criteria and saves it as a JSL command with the current data table in a table property called Filter.

to Script Window: Creates a WHERE clause from the filter criteria and appends it to the current script text window, or creates a new script if one does not exist already.

to Journal: Creates the WHERE clause from the filter criteria and appends it to the current journal, or creates a new journal if one does not already exist.

Script: Provides options for saving scripts. Red Triangle Options for Variables

Some of the red triangle options for a variable can vary, depending on the type of variable.

Options for All Types of Variables

The red triangle menu next to any type of variable contains the following generic options:

Delete

Removes the variable from the Data Filter control panel.

Clear Selection

Clears any selection in effect for that variable only.

Invert Selection

Deselects any selected values, and selects all values previously not selected, for that variable only.

Display Options

Changes the appearance of the display. Options can include the following:

Blocks Display shows each level as a block.

List Display shows each level as a member of a list, followed by its frequency.

Single Category Display shows each level, followed by its frequency, in a menu.

Check Box Display adds a check box next to each value.

Order by Count

Orders the values in decreasing sort order by count.

Find

Provides a text box where you can enter a search string for the selected column. Press the Enter key to perform the search. Once Find is selected, the following Find options appear in the red triangle menu:

Clear Find clears the results of the Find operation and returns the window to its original state.

Match Case uses the case of the search string to return the correct results.

Contains searches the data for values that includes the search string.

Does not contain searches the data for values that do not include the search string.

Starts with searches the data for values that start with the search string.

Ends with searches the data for values that end with the search string.
