How do I display the values for the harmonic cursors on a diagram? I can place the cursors in the diagram, but I can’t find a way to display the amplitude values at each cursor.

First, you create a formula which returns the Y and X values of the harmonics as a signal and then you create a column table to visualize these values. Finally you display that table in the coordinates window.
The formula should look as follows:
[code]
Dim idx, orders
orders = (10, 1, 1.0)
idx = ‘2D Diagram.2D’.CursorIndexX(0, 0)
spectrum[orders * idx]
[/code]In this example the orders 1.0, 2.0, … 10.0 are displayed. You can easily include the half multiples by setting the increment to 0.5.
The formula returns a signal with ten Amplitudes and frequency values. Just klick on the Table Wizard Icon to create a column table for it.
To place the column table in the coordinate window of the 2D diagram, proceed as follows:
[ol]
[li]Click on the name on the table column in FlexPro Explorer and drag it to the diagram.[/li]
[li]There you wait a moment until the diagram is displayed in the foreground and its coordinate window is displayed.[/li]
[li]Then you drag the table to the coordinate window and drop it there.[/li]
[/ol]Please note that in the new [b]Spectral Analysis Option[/b] there are algorithms available to automatically identify and extract the harmonics from signals.
