Validating and Applying the Expression String			Associating Comments with an Expression
Chapter 24, Expressions

You can view a valid expression in a graph view by clicking the Graph button. The graph view displays the shape of the expression curve plotted over time. The initial time extents are the same as those of the composition.

You can also display the expression curve in the Animation Curve Editor Viewer with other animation curves. The expression curve is visually differentiated by being displayed in a green line and will always appear underneath animated curves. The expression curves cannot be selected nor modified. To Display the curve, select the attribute containing the expression from the Composition Browser.

Note: You can zoom the view by placing the cursor inside the view and using the Up and Down arrow keys, or by using Ctrl + Space + click. You can also pan the view by simultaneously holding down the Spacebar on the keyboard and the left mouse button.

Note: To return to the main Expresso Calculator view, select the Graph button again.
