===3D group waterfall display===
This group provides general purpose tools about the Waterfall 3D graphs.
[[Image:Reports_Tools_Ribbons_470.png|framed|none]]
The first button corresponds to displayed graphs. Each Waterfall windows may displays up to 4 different graphs. It is a multi-action button.
* [[Image:Reports_Tools_Ribbons_471.png]]3D only:  Shows the 3D graph only. This graph can be a 3D plot or a color map.
* [[Image:Reports_Tools_Ribbons_472.png]]X/Y only:  Shows the X/Y extraction graph only. This graph contains the spectra at the cursor position and the X/Y sections.
* [[Image:Reports_Tools_Ribbons_473.png]]Y/Z only:  Shows the Y/Z extraction graph only. This graph contains the time (or ref) profile at the cursor position and the Y/Z sections.
* [[Image:Reports_Tools_Ribbons_474.png]] Extraction only:  Shows the Order/frequency extraction graph only. This graph contains the order/frequency profile at the cursor position and the extraction sections.
* [[Image:Reports_Tools_Ribbons_475.png]] All graphs:  Shows all the graphs in a matrix.
The second button controls which way the 3D data are plotted. It is a multi-action button.
* [[Image:Reports_Tools_Ribbons_476.png]]3D Isometric:  Plot the spectra (or trigger blocks) along a Z axis with the same scale whatever is the position. The Z axis angle is modified by the rotate button.
* [[Image:Reports_Tools_Ribbons_477.png]]3D perspective:  Plot the spectra (or trigger blocks) in a true 3D space, taking in account the perspective. The global orientation of the gathered spectra can be changed using the rotate button. This type of view allows looking at the waterfall from any side
* [[Image:Reports_Tools_Ribbons_478.png]]Time/frequency color map:  Plot the spectra (or trigger blocks) on 2D map with the color representing the point amplitude. This plot show the Time (Y) Vs frequency (X) arrangement
* [[Image:Reports_Tools_Ribbons_479.png]]Frequency/time color map:  Plot the spectra (or trigger blocks) on 2D map with the color representing the point amplitude. This plot show the Frequency (Y) Vs Time (X) arrangement
The last 3 items control the 3D graph rotation and manage the sections:
* [[Image:Reports_Tools_Ribbons_480.png]] Rotate:  Toggle the rotating mode. Allows rotating the 3D graphs with the mouse when enabled. Disabling this item return the mouse to the previous mode.
* [[Image:Reports_Tools_Ribbons_481.png]] Add section:  Add  a copy of the cursor location in each of the 3 extraction graph
* [[Image:Reports_Tools_Ribbons_482.png]] Section manager: Open the waterfall section manager.
=====3D view=====
There are 4 different views only available in 3D Waterfall areas..
1. 3D isometric
[[Image:Display_Graphs_Traces_05.png|framed|none]]
2. 3D perspective:
3. Freq/Time Colormap:
[[Image:Display_Graphs_Traces_06.png|framed|none]]
4. Time/Freq Colormap:
The 3D aspect can be swapped any time using the ''Display/Graps'' tab and ''3D'' group
=====Sections=====
Waterfall display provides extraction of section from the 3D space
[[Image:Display_Graphs_Traces_118.png|framed|none]]
These sections are linked with cursors of the 3D view:
* Fig1: for a fixed value of the X-axis of the 3D view,
* Fig2: For a fixed value of the reference
* Fig3: for a fixed value of the order (follow the evolution of an order) or frequency for order spectra waterfall.
During the acquisition, an autoscale is available on the z-axis (reference) if <nowiki>’</nowiki>z Adjust<nowiki>’</nowiki> is active.
[[Image:Display_Graphs_Traces_119.png|framed|none]]
The <nowiki>’</nowiki>Select Tacho<nowiki>’</nowiki> mode allows tracking an order in function of the selected tachometer. The extraction order could be done in function of the selected tacho.
4 Graphs are available for the windows allowing tracking different results:
9. 3D view: you can select by right-clicking on it an isometric view, a perspective view, a freq/time colormap or a time/freq colormap (useful to track orders). The 3D view is the default view.
10. 2D views: - XY section,
* YZ section,
* Order extraction (only available if a tachometer is active).
[[Image:Display_Graphs_Traces_120.png|framed|none]]
The sections are displayed in these 2D views. The sections can be managed in the section manager window (see waterfall window in chapter2 <nowiki>’</nowiki>Display<nowiki>’</nowiki>).
In the section manager, add section made a copy of each cursor (Frequency, Reference, Order) in all displayed windows. These memorized traces could be added to result by the <nowiki>’</nowiki>add to result selection.
The waterfall sections can be saved as independent results (spectra, reference profiles, extracted profiles).
The selection is achieved using the "Add to result selection" entry from the waterfall window contextual menu.

After being saved, the sections became independent results, reducing the amount of saved data when you are focusing only on extracted data.

* '''Add section: '''Creates a new section at the current position of the cursor. The extraction section is created only if a tach has been selected in the Waterfall.
* '''Select YZ section: '''Selects the active trace in the YZ graph. Useful to get the value of the cursor for this section
* '''Select XY section: '''Selects the active trace in the XY graph. Useful to get the value of the cursor for this section
* '''Select extraction section: '''Selects the active trace in the extraction graph. Useful to get the value of the cursor for this section
* Section manager: This dialog box is used to create and modify sections.
To modify a section, select the desired type and the desired section then modify the Section properties and click "Apply".
To create a new section, Select the type, set the desired properties and click "Add"
To remove a section, select the desired type and the desired section, then click "Remove".

* Section properties: The XPos, ZPos, Freq or Order defines the position of the section in the Waterfall.
When the "Advanced" box is checked, it defines the center of the band.
The width is used when the "Advanced" box is checked. It defines the bandwidth.
The advanced sections are:

* ''Z-Operator'':
This Operator is available on XY extraction view and 3 operators are available: Min, Max and Arithmetic Average.
[[Image:Display_Graphs_Traces_71.png|framed|none]]
* ''Order Extraction'':

[[Image:Display_Graphs_Traces_72.png|framed|none]]
This Operator take data spectrum by spectrum, for each spectrum there is a determination of the max value and of the corresponding order.
Using this operator it is possible to detect on which orders it is useful to work.
Note: The Max Order cannot be saved in result (not available in the <nowiki>’</nowiki>Add to result selection<nowiki>’</nowiki>).
* View: Displays all the views or only one of the three or four available views (sections, 3D)
* Z auto scale: Adjusts the Z-scale to the current range of the selected reference
* Select reference: Reference used for the Z-Axis
* Select tach: Selection of the tach that is used for the order or frequency extraction
* Add to result selection: Check the Waterfall box to add the Waterfall to the result selection.
Check the section that must be added to the result selection. These sections will be saved as individual results (spectra, trigger blocks...)

The orientation of the 3D view of the waterfall can be modified by using the rotation button
