Introduction

The Graph Editor allows users to adjust animation curves over time for any animatable property. F-Curves.

The Graph Editor.

Main Region

The curve view allows you to view and edit F-curves. An F-curve has several key parts:

Curve

The curve defines the value (Y axis) of the property over time (X axis).

See F-Curves.

Keyframes

Keyframes are user-defined values on certain frames and are represented by little black squares which become orange if selected.

See Keyframes for more information.

Handles

Each keyframe has a handle that helps determine the values of the curve between keyframes. These handles are represented by extruding lines with circular ends and can be selected and modified to change the shape of the curve.

See Handle Types for more information.

A simple curve.

Navigation

As with most editors, you can:

Pan

Pan the view vertically (values) or horizontally (time) with click and drag MMB.

Zoom

Zoom in and out with the mouse wheel Wheel.

Scale View

Scale the view vertically or horizontally Ctrl-MMB.

In addition, you can also use the scrollbars to pan and zoom the view.

Playhead & 2D Cursor

Graph Editor 2D Cursor.

The current frame is represented by a blue vertical line called the Playhead.

As in the Timeline, you can change the current frame by LMB-dragging in the scrubbing area at the top of the editor.

The blue horizontal line is called the 2D Cursor. This can be enabled or disabled via the View Menu or the View Properties panel.

These two lines can be used as a reference for moving and scaling keyframe handles.

See Graph Editor's View Properties.

View Axes

For Actions the X axis represents time, the Y axis represents the value to set the property.

Depending on the selected curves, the values have different meaning: For example rotation properties are shown in degrees.

Realtime Updates

When transforming keyframes, changes to the animation data are propagated to other views.

Show Cursor

Toggles the visibility of the Playhead & 2D Cursor.

Show Sliders

A toggle option that shows the value sliders for the channels. See the Fig. The Action editor's channels region..

Show Group Colors

Display groups and channels with colors matching their corresponding groups.

AutoMerge Keyframes

Automatically merge nearby keyframes.

Use High Quality Display

Display F-curves using anti-aliasing and other fancy effects (disable for a better performance).

Show Handles Ctrl-H

Toggles the display of a curve's handles in the curve view.

Only Selected Curve Keyframes

Only shows the keyframes markers on the selected curves.

Only Selected Keyframes Handles

Only shows the handles for the currently selected curves.

View All Home

Reset viewable area to show all keyframes.

View Selected NumpadPeriod

Reset viewable area to show selected keyframes.

View Frame Numpad0

Centers the area to the Playhead.

Preview Range

Set Preview Range P

Interactively define frame range used for playback. Allows you to define a temporary preview range to use for animation playback (this is the same thing as the Playback Range option of the Timeline editor header).

Clear Preview Range Alt-P

Clears the preview range.

Auto-Set Preview Range Ctrl-Alt-P

Automatically sets the preview range to playback the whole action or the selected NLA strips.

Markers Menu

Markers are used to denote frames with key points or significant events within an animation. Like with most animation editors, markers are shown at the bottom of the editor.

Markers in animation editor.

For descriptions of the different marker tools see Editing Markers.

View Controls

View controls.

Show Only Selected (mouse cursor icon)

Only include curves related to the selected objects and data.

Show Hidden (dashed object icon)

Include curves from objects/bones that are not visible.

Show Only Errors (warning triangle icon)

Only include curves and drivers that are disabled or have errors. Useful for debugging.

Filter popover (funnel icon)

Only include curves with keywords contained in the search field.

Multi-Word (az icon)

Fuzzy/Multi-Word name filtering matches word snippets/partial words, instead of having to match everything. It breaks down the search string based on white-space placement. e.g. "lo ro" will filter all location and rotation, while "lc rt" will not work.

Type Filter

Filter curves by property type.

Data-block Sort (az icon)

Objects data-blocks appear in alphabetical order, so that it is easier to find where they occur (as well as helping to keep the animation of related objects together in the NLA for instance).

If you find that your playback speed suffers from this being enabled (it should only really be an issue when working with lots of objects in the scene), you can turn this off.

Normalize

Normalize curves so the maximum or minimum point equals 1.0 or -1.0.

Auto

Automatically recalculate curve normalization on every curve edit. This is useful to prevent curves from jumping after tweaking it.
