Changing the Ordinate Unit of the Order Levels Graph

The order levels are displayed in the original linear unit of the temporal signal versus time. When the original unit of the temporal signal is Pa, the order levels may be displayed in Pa vs. time, dB SPL vs. time, or dB(A) vs. time.

Note: When the initial signal's unit is not Pa, the display unit cannot be changed from the signal's original unit.

Prerequisites: You must already have created a Graph to display order levels over time as described in Displaying Order Levels in a Graph.

To Change the Units of the Order Level Graph:

1. Right-click the graph to display the context menu.
2. Choose the Change Y axis submenu.
3. Choose the desired unit from the Change Y axis submenu.

If the initial signal's unit is not Pa, the Change Y axis submenu will not be available.
