| # Compare two grids |

You have chosen to compare the similarities and difference between two conceptual representations.

The compare algorithm sorts the differences between and the in the two grids to bring the most similar items to the left and top.

It plots the matches between items in the grids as a graph.

## Showing a list of your Compare 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.

## Compare Parameters

There are four sub-sections to the Compare Parameters panel, the top row of buttons, "Plot" section, "Style" section and "Use" section.

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

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

- Copy the plot in a separate window so that you can retain a copy.
- Download the plot as a scalable vector graphics (SVG) file.
- Download the plot as a PNG file at one of 3 resolutions.
- Download the plot as a JPG file at one of 3 resolutions.

  ## Plot the analysis graphically

  The "Plot" check box when checked causes the Compare 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 "Scale" value specifies the width of the and graphs.

  The "Cutoff" value specifies how low a match is to be shown in the and graphs

  The "Threshold" value specifies where a threshold of good and poor matches is to be shown in the and graphs

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

  The radio buttons under "Graph Matches" determine whether numeric values of the matches and cumulative percentages will shown.

  The check boxes under "Direction" determine which grid should be the basis of the comparison.

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

  If the comparison is based on both common and common The radio buttons under "Comparison" determine whether the comparison should use the Minus technique to show differences or that items should be separately matched.

  The check box under "Minus Format" determine whether a Minus analysis should show the rating differences or the actual ratings.

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

  ## 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.
