RuCd - Waterfall extended set-up

* Z-Axis - Select from the drop-down menu the spacing to use for the Z-axis. Choose from:
 RPM - the FFTs will be spaced depending on the RPM at which they were recorded
 Timestamp - the FFTs will be spaced depending on the time the data was recorded
 Even spacing - the FFTs will be evenly spaced along the Z-axis

* No. Spectra -Use the numeric keypad to enter the number of Spectra to be displayed on the waterfall. The user can display between 2 and 60 traces.

* Trace Offset - Use the drop-down menu to select the angle of the waterfall Z-axis. Choose between 0, 22.5 and 45 degrees from the Y-axis.

* Trace Height - Use the drop-down menu to control the amount of the screen used for the Y-axis and the Z-axis: if High, then spectra are taller but closer together; if Low, then spectra are lower and further apart.

* Disp Order - Select whether to display the order of the plot in forward or reverse. If Display order is Forward, then the spectrum nearest the user is the earliest collected spectrum of those displayed, with later collected spectra behind it. If Display order is Reverse, then the spectrum nearest the user is the latest collected spectrum of those displayed, with earlier collected spectra behind it

* Blanking - Select from the drop-down menu the percentage of the overall signal data to be blanked. This will suppress the data below a certain level on the Y-axis.
