Specifying the Graph Type

The Graph Editor can represent any property as a value graph or speed graph. Turn back to the section “Understanding Value and Speed Graphs,” earlier in this chapter, to review how the graphs work. Later sections explain how to manipulate the graphs.

To specify the graph types displayed in the Graph Editor:

  1. In the Graph Editor, click the Graph Type and Options button, and then choose any of the following options in the pop-up menu (Figure 9.45):
    • Auto-Select Graph Type—After Effects determines the most appropriate type of graph to display for editing.
    • Edit Value Graph—After Effects displays the visible properties’ value graph for editing.
    • Edit Speed Graph—After Effects displays the visible properties’ speed graph for editing.
  2. In the Graph Editor, the type of graph you choose appears for the visible properties (Figure 9.46).

    Figure 9.45 Selecting an option in the Graph Editor’s Graph Type and Options pop-up menu...

    Figure 9.46 ...displays that type of graph for the visible property. Here, the property’s speed graph is visible for editing.

  3. To display the type of graph you did not specify in step 1 for reference, select Show Reference Graph (Figure 9.47).
  4. For example, if you chose Edit Speed Graph in step 1, then selecting Show Reference Graph makes the value graph visible. However, you can’t edit the reference graph (Figure 9.48).

    Figure 9.47 Selecting Show Reference Graph...

    Figure 9.48 ...makes the other graph visible (in this case, the value graph). The reference graph can’t be edited, but it reflects the changes you make to the other graph.
