Focus Cluster your grid data

You have chosen to analyse your conceptual representation using the Focus Cluster method.

The Focus algorithm sorts both the and the to bring similar and together.

It plots the matches between items as a tree.

Showing a list of your Focus Cluster Parameters

You can show or hide a list of the parameters that control what is displayed.

Clicking on shows them, and clicking on hides them.

Focus Cluster Parameters

There are five sub-sections to the Focus Cluster Parameters panel, the top row of buttons, "Plot" section, "Text" section, "Style" section and "Use" section.

Clicking on the "Focus Cluster" button causes the plot to be produced again with the new parameters.

Clicking on the "Continue" button returns to the main page.

Clicking on the "Image" button on the left displays a menu of options for preserving the current plot:

Plot the analysis graphically

The "Plot" check box when checked causes the Focus Cluster analysis to be plotted.

The "Title" check box when checked causes the plot to be titled.

The "Numbers" check box when checked causes the and numbers to be shown.

The "Shading" check box when checked causes the ratings to have a background shading according to their value.

The "Interior" check box if checked specifies that items may be matched to interior items of a cluster, not just its edges.

The "Scale" value specifies the scale of the and trees
(or the scale and scale separated by a comma if different, e.g. 70,150)

The "Power" value specifies the Minkowski metric used in the cluster distance measure.


The radio buttons under "Rows" determine whether the rows in the display will be the or the .

The check boxes under "Notes" determine whether the annotation of the and/or will be shown in parentheses after their names.

The radio buttons under "Tree" determine whether the tree associated with the columns should be at the top or on the right side.

The "Cutoff" values specify how low a match is to be shown in the and trees respectively

The radio buttons after "Values" determine whether values should be shown as numbers or categories, as specified in the grid or as forced by the analyst.

Output the analysis in textual form

The "Text" check box when checked causes the Focus Cluster analysis to be output in textual form.

The check boxes determine whether matches, links and sorts will be shown for the and .

Set the style of the plot

The "Style" sub-section top row allows the font and font size used in the plot to be changed, and the plot to be shown without a background or in black and white.

The next two rows enable the colors used in the plot to be specified by clicking the color swatches.

The final row enables the identifier used in the plot title to be specified. An item may be created on the "Options" page named "ID" and used as a customized identifier for the grid, and/or some combination of the name, note, date and time may be specified. If nothing is specified the default identifier is the name followed by the note in parentheses.

The style parameters are common to all analyses so that changing them in one applies consistent changes to the others.

Use selected items and weights

The "Use" sub-section specifies whether only selected and will be displayed.

The "All" button at the top selects all and to be analyzed (equivalent to selecting all of them on the main page).

If any of the "Data Types" check boxes on the main page are checked this sub-section also gives the options to use and weights in analyses.

The selection and weight parameters are common to all analyses so that changing them in one applies them to the others.
