Grapher
Color information can be complicated - and 2D and 3D graphs aid visualization and help in evaluating profiles, devices and printing processes. The Grapher will plot the gamut surface (or outline) of ICC device and Space profiles - and the color list from Named Color Profiles (NCP) in (Y)xy, (L)uv, or (L)ab coordinates. It will render the pixels from image files. It will also plot color lists resulting from measurement data and synthetic test data.
Device profiles include:
Scanner/Camera (“scan”)
Monitor (“mntr”)
Printer (“pntr”) types
Note: Device Link (“link”) and abstract (“abst”) profiles have no discernible gamut surface and therefore cannot be plotted as surfaces. Their effects, however, can be graphed. For instance, an abstract profile can be applied to image / color data to create a vector graph.
Keyboard Shortcuts
While in the Grapher...
To Turn on the Slicer
Press control/command-S to turn on the slicer function.
To Open a profile from the Plot list into the Profile Inspector
Double-click the profile in the Plot list.
To open a gamut surface’s points into the worksheet as a colorlist
Hold down the option key and double-click the profile in the plot list.
To nudge the rotation of the Grapher:
Use the four arrow keys.
To nudge the rotation of the Grapher by a small amount (25%):
Hold down the command key (Mac) while using the four arrow keys.
To hide the wireframe backgrounds, choose “H”.
To switch between LCH and the regular 3D-viewing scene, choose “C”.
Grapher Help Menu
There is also a Grapher Help page which lists many of these shortcuts. Click the 
? in the top right corner of the Plot Items pane.
Keyboard Shortcuts:
delete - removes item from plot list
left/right arrows - rotate graph left / right, nudges rotation if using inertia (3D)
up/down arrows = rotate graph up/down (3D)
space - stop rotation if using inertia
g - gridlines on/off
s - slicer on/off
t - "Tone using L*" on/off
command/control - 2/3 - toggle between 2D and 3D mode
Mousing:
shift-drag - move graph around left/right(3D) and up/down
option/alt-drag - zoom in/out using mouse up/down movement
command/control-drag - move slicer up/down
Numeric Keypad:
1 - 9 - type the number that corresponds to your saved Views
'-' - slicer on/off
