Modify the Curve Data

1. Select one or more curves to modify.
2. Define the range of the curves to modify.
3. Under Action, click Delete/Shift, Delete, Trim, Bridge, or Hide.

   Delete/Shift

   Removes the data within the selected range and closes any gap created by this action.

   Delete

   Removes the data within the selected range without closing any gaps created by this action. Delete can only be used at the beginning or end of the curve.

   Trim

   Removes the data outside of the selected range.

   Bridge

   Bridges the curve linearly across the selected range. This replaces the data in the selected range with a straight line on a point by point basis.

   Hide

   Turns off curve points within the selected range, but does not remove any gaps created by this action.

   Replace

   Enter an expression in the Replace with Expression text box and use x and y as variables for the selected range. Click Replace to replace the points in the selected range with the expression.

4. If Interpolate is turned on, a point is inserted using the From or To values and performs the action.
5. If Interpolate is turned off, the closest point is found for the selected curves based on the From/To values and performs the action.

Or

6. Enter an expression in the Replace with Expression text box.
7. Use x and y as variables for the selected range.
8. Click Replace.
   The expression replaces the points in the selected range. For example, -y will flip all points in the selected range about the x-axis. y+1 will move the selected range up by 1 (assuming a horizontal range is selected).
