The Graph Editor allows users to adjust animation curves over time for any animatable property. F-Curves.
The curve view allows you to view and edit F-curves. An F-curve has several key parts:
The curve defines the value (Y axis) of the property over time (X axis).
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.
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.
See F-Curves for more info.
Playhead & 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.
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.
- 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 curves so the maximum or minimum point equals 1.0 or -1.0.
Automatically recalculate curve normalization on every curve edit. This is useful to prevent curves from jumping after tweaking it.
- Proportional Editing O
See Proportional Editing.
- Auto Snap
Auto snap the keyframes for transformations.
- Pivot Point
Pivot point for rotation.
- Bounding Box Center
Center of the selected keyframes.
- 2D Cursor
Center of the 2D Cursor. Playhead + Cursor.
- Individual Centers

- Create Ghost Curves (framed F-curve icon)
Creates a picture with the current shape of the curves.
