4. From the filter menu, select one of the following actions:

   Removes the data outside of the selected range.

   Delete

   Hide

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

   Replace

   Click Expression to replace the points in the selected range with the expression. You can also replace curve points (on a point-by-point basis) within a specified range with an expression. 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.

   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.

   Shift/Delete

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