The Relations tool is a popup window, opened by:
Toolbar: 
Keyboard: Ctrl+R
Menu: Tools-Relations
It can also be opened with the button above where it appears in other popup tools, and from the right-click popup menus.
The Relations tool allows you to see which scales and chords are related to each other by the notes they are made up of.
It is similar in operation to the Chords and Scales mode of Relations View.
Relations can be used as a musical thesaurus, prompting chord possibilities for songwriting, or indicating scales that you can use for improvisation over a chord.
For details on using Relations for these purposes, see Relations and Songwriting or Relations and Improvisation in Tutorials View.
The Chord Matrix and Scale Matrix are colored blue and red respectively as with other areas in the ChordWizard workspace. You can change these colors with the Display Options.

Scale Matrix
Chord Matrix
There is a matrix each for scales and chords. Each cell in the matrix represents the chord or scale based on the chord or scale type in the row heading and the root note in the column heading.
By selecting a scale in the Scale Matrix (upper in the box), red dots appear in the cells of the related chords in the Chord Matrix (lower in the window). The same can occur (simultaneously) in the opposite direction, with blue dot indicators.
The example below shows the situation for a selection of D Dorian in the Scale Matrix and Dm in the Chord Matrix.
The name of the selected scale or chord appears above each matrix.
Set Filter to Scale
Sends the scale currently selected in the Scale Matrix to the filter. This helps you find suitable scale positions for playing the scale in Scales View when you return to the workspace.
Play Scale
Plays the scale currently selected in the Scale Matrix. It is disabled if there is no scale selected.
Scale Sizes
Instead of showing all scale types, you can reduce the rows of the Scale Matrix down to those of just particular sizes (numbers of notes). The following sizes can be individually included or excluded from the matrix:
5 or less - eg. Major Pentatonic, Minor Pentatonic
6 Notes - eg. Blues
7 Notes - eg. Major, Harmonic Minor
8 or more - eg. Major Bebop
If you are not sure what the size of each displayed scale type is, you can tick the Show Sizes option to have the size appear in square brackets in the matrix row headings, for example Major [7].
Set Filter to Chord
Sends the chord currently selected in the Chord Matrix to the filter. This helps you find suitable chordshapes for playing the chord in Library View when you return to the workspace.
Play Chord
Plays the chord currently selected in the Chord Matrix. It is disabled if there is no chord selected.
Chord Sizes
Instead of showing all chord types, you can reduce the rows of the Chord Matrix down to those of just particular sizes (numbers of notes). The following sizes can be individually included or excluded from the matrix:
3 or less - eg. maj, m
4 Notes - eg. 7, maj7, m7, 6
5 Notes - eg. 9, maj9, m9, 6add9
6 or more - eg. 11, m11, 13
If you are not sure what the size of each displayed chord type is, you can tick the Show Sizes option to have the size appear in square brackets in the matrix row headings, for example maj [3].
Allow Multiple Selection
This option expands the scope of the Relations tool by allowing you to select more than one chord at once in the Chord Matrix, and more than one scale at once in the Scale Matrix. You can make a multiple selection in a matrix by holding down the Ctrl key for each additional cell you want to select.
This reveals which scales are most closely related to a series of chords (similar to the Chord To Scales tool) and which chords are most closely related to a series of scales.
The related chord and scale cells will now be indicated not with a colored dot, but a number.
For example, selecting both Cmaj and Dm chords would make the number 2 appear for the scale C Major, since it is a relation of both chords. By contrast, G Major would only be indicated with the number 1, because it is a relation of Cmaj but not Dm.

Closes the Relations window and returns to the workspace.
