The Drivers Editor.

Main Region

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

Axes

The curve defines the relationship between two properties: The current (driven) property (Y axis) and the driver (X axis).

See F-Curves.

Handles

Each point on the driver curve has a handle that helps determine the relationship between the two values. They can be selected and modified to change the shape of the curve.

See Handle Types for more information.

Normalize

Normalize curves so the maximum and minimum points equal 1.0 and -1.0 respectively.

Auto

Automatically recalculate curve normalization on every curve edit. Disabling this setting may be useful to prevent curves from jumping after tweaking.

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.

Create Ghost Curves (square with curve icon)

Makes a visual indication in the background of the editor with a snapshot of the current state of the selected curves. This is useful to have a base for comparison on top of which to make edits.

Filter (funnel icon)

Type Filter

Filter curves by property type.

Sort Data-Blocks (az icon)

Object 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).

This option may affect the playback speed for heavy scenes.
