This section explains all the functions and information you can find in the graphs, windows and infotrace. It contains also the information relative to the scales, graphic modes, display modes and the contextual menus.


===Introduction===
This section explains all the functions and information you can find in the graphs, windows, infotrace. The Display chapter also contains the information relative to the scales, graphic modes, display modes and the contextual menus.


====Add/remove====
Different windows which contain one or more graphs or traces can be created using the [[NVGate_GoToResult#Step_2_Show_results|''Results'' dialog]] or the [[NVGate_Ribbons:_Display/Graph_Tab#Add.2Fremove_window|''Add/remove window'' dialog]]. You can also add or remove some information in the Infotrace using the Infotrace properties. Manage all the display settings using the right click in almost any area. For each result type there are different available options using the right click.
Allows to display the measurement results of the active plug-in analyzers.


You can display the Add/Remove window from the '''Display''' tab.

The maximum number of traces, windows and layout available are:
<Youtube>https://www.youtube.com/watch?v=CuUHne-GEVQ</Youtube>


* 32 Traces per Window
* 32 Windows per Layout
* 16 Layouts per project.
===Display Window===
The windows allow to display signal traces. They can contain several traces in the same graph (multi-trace display) or several graphs (multi-graph display). The windows can display 1D graphs (viewmeter, RPM monitoring), 2D graphs (profiles, signal recording) or 3D graphs such as Waterfall display.

* Always on top: the window will be on top
* Default: reset the all the settings to the default settings
* Apply to: applies the settings either to All windows or just for the Active window
* Save as user preferences: save the properties settings
 
=====Active trace=====
Select the active trace of the window. When the signal changes, the Y scale is updated to the Y magnitude of the signal. Only signals with the same Y magnitude as the active signal are displayed. The others are displayed as unavailable in the info-trace.
 
The color of the cursor corresponds with the trace<nowiki>’</nowiki>s color; you can select in the infotrace the active trace and its linked cursor using arrays of the keyboard.
 
=====Remove trace=====
Removes selected trace from the window. If this trace is the active one, the active signal is changed. A trace can be removed using <nowiki>’</nowiki>Ctrl suppr<nowiki>’</nowiki>.
 
=====Memorize trace=====
Memorizes the active trace of the active window at any time (independently from Run and Stop event).
 
The memorized trace is named ''Memx: active trace name.  ''There<nowiki>’</nowiki>s an incrementation of the memorized traces id (x). You can save the memorized traces by adding it to the result selection.
 
<font color="#FF0000">
[[Image:Display_Graphs_Traces_37.png|framed|none]]
 
</font>'''Note''': you can memorize an active trace by using the insert button of the keyboard.
 
=====Clear memory=====
Clear all memorized traces. You can remove specific memorized traces with the <nowiki>’</nowiki>Remove trace<nowiki>’</nowiki> command.
 
=====AutoMemorize=====
 
[[Image:Display_Graphs_Traces_38.png|framed|none]]
 
<nowiki>’</nowiki>AutoMemorize<nowiki>’</nowiki> traces consists in memorizing traces on the stop event. Select the graph to be memorized.
 
By using an operator on an active trace and his associated memorized traces is available by right-clicking on the graphs and selecting <nowiki>’</nowiki>operators<nowiki>’</nowiki>. This operator will be automatically updated if a memorized trace is added or deleted (see also operators).
 
During a multi-run, the average on automatic memorized trace is done automatically for each run, and the average trace is automatically updated.
 
=====Auto scale Y on all=====
Sets min and max values of the Y scale to the Y min and max values of all signals displayed in the graph. A margin is added to these values to facilitate visibility. The Y width is always more than Y active signal precision.
 
=====Cascade view=====
Present the current active trace in a cascade view of the last 50 (default value) recovered results.
 
This is dedicated for monitoring used, this is not a waterfall (acquisition mode in real-time). The Z-axis represents the number of slices independently from any reference such as time or RPM evolution.
 
This function is available only for 2D spectra and trigger blocks.
 
'''Warning''': if you are in manual trigger, or if there is an absence in the time, you won<nowiki>’</nowiki>t be able to notice it with the cascade view. In the following example, a pause has been made during the measurement; on the waterfall 3Dview (with time for reference) it is possible to see this pause. In the cascade view the pause won<nowiki>’</nowiki>t be noticed (number of block for reference).
 
[[Image:Display_Graphs_Traces_39.png|framed|none]]
 
=====Unit=====
These commands are available only for results with an X-Axis that represents frequencies. The operations are performed in the spectral domain
 
* '''RMS: '''Provides the RMS (EU) value. This is the default unit.
* '''Peak: '''It is based on a sine signal, and therefore equal to 1.414 times the RMS value.
* '''Peak-Peak: '''It is based on a sine signal, and therefore equal to 2.828 times RMS value.
* '''EU²: '''Means Square value.
* '''PSD (EU²/Hz): '''Calculates the Power Spectral Density of the result. The formula used is:
 
[[Image:Display_Graphs_Traces_44.png|framed|none]]
 
Where ENBW is the Equivalent Noise Band Width that takes into account the weighting windows (1 for Rectangular, 1.5 for Hanning, 1.36 for Hamming, 3.77 for Flat top) and ''val'' the RMS value.
 
* '''ESD (EU²/Hz²): '''Calculates the Energy Spectral Density of the result. The formula used is:
 
[[Image:Display_Graphs_Traces_45.png|framed|none]]
 
Where ENBW is the Equivalent Noise Band Width that takes into account the weighting windows (1 for Rectangular, 1.5 for Hanning, 1.36 for Hamming, 3.77 for Flat top) and ''val'' the RMS value.
 
* '''RMS PSD (EU/Hz'''<sup>'''1/2'''</sup>'''): '''Calculates the RMS Power Spectral Density of the result. The formula used is:
 
[[Image:Display_Graphs_Traces_46.png|framed|none]]
 
Where ENBW is the Equivalent Noise Band Width that takes into account the weighting windows (1 for Rectangular, 1.5 for Hanning, 1.36 for Hamming, 3.77 for Flat top) and ''val'' the RMS value.
 
=====Weighting=====
These commands are available only for results with an X-Axis that represents frequencies. The operations are performed in the spectral domain
 
* '''None: '''No weighting is applied.
* '''A Weighting: '''Selects the "A" weighting
* '''More: '''Used to select specialized weighting
<br>See more details about Weightings in chapter "Appendix 2, Weighting Windows and Filters".
 
=====Add to Result selection=====
This command adds all the results displayed in the window to the list of results that must be saved in a measurement. If the result is already on the list, it is not added. Some results displayed cannot be saved (Instant trigger of the front end, profile of a DC input).
 
=====Copy graph(s)=====
This command copies the active graph in the format <nowiki>’</nowiki>wmf<nowiki>’</nowiki>, this command is not available for 3D Waterfall.
 
=====Copy bitmap=====
This command copies graph in the format <nowiki>’</nowiki>.bmp<nowiki>’</nowiki>
 
=====Copy data=====
This command copies data in order to export them in Excel. This will export all point<nowiki>’</nowiki>s values from the active graph. NVGate export values with a point as separator and in engineer mode. This command is available for all spectra and profiles (even waterfall profiles).
 
If the graph is displayed with complex values, then the <nowiki>’</nowiki>copy data<nowiki>’</nowiki> command allows to export phase and module values.
 
Example:
 
* Natural values:
Values displayed are values from the Active trace:
 
[[Image:Display_Graphs_Traces_63.png|framed|none]]
 
* Complex values:
For complex values the <nowiki>’</nowiki>Copy data<nowiki>’</nowiki> will displayed phase and module values.

=====Copy to Mask=====
Adds the result to the project template results. This result is then available for editing and use as a template.
 
=====Add Alarm=====
Dialog box to create an alarm. An alarm compares a dynamic signal with a template result. The result of the comparison can be used in the macro to perform certain tests.
 
To make this option available, a result template must be added to the window (using drag & drop for example).
 
[[Image:Display_Graphs_Traces_65.png|framed|none]]
 
Go to the "Chapter 5: Tools" to see more details about the Result template.

=====Sections=====
=====Orbit=====
Displays the AC dynamic motion of the center of a rotating shaft. It generates a two-dimensional image.
 
'''Source Signals'''<br>
 
The following results may be displayed as Orbit graphs on condition that a tachometer is associated to the plug-ins:
 
* FFT x: Raw Orbit, Synthetized Orbit  ( for customer with FFT-diag option)
* SOA x: Raw Orbit, Synthetized Orbit  (For customer with ORD-Diag option)
 
Note :
[[Image:Display_Graphs_Traces_122.png|framed|none]]
 
The Raw Orbit graph displays an entire number of complete rotations contained in one block. At least one rotation is required.
 
The FFT should better be triggered by the Ext. Sync. channel.
 
If the FFT is bad configured, it is possible that no results are shown.<br>
The FFT synthtetized Orbit is only available for customer with FFt-CBT option.
The FFT synthetized Orbit is filtered using CBT technics. this method provide a non accurate phase value on synthetiseed orbit. For acurate  synthetize Orbit phase, you need to use the SOA Synthetized Orbit.
 
 
The ORD Synthesized Orbit graph is calculated with the orders of two channels selected. For a couple "ChannelA, ChannelB" up to 8 Synthesized Orbits can be selected. Each orbit corresponds to an order which appears in the tracked order setting.
 
The display of the Synthesized Orbit is done on 360 points (1 point per degree).

|'''Multi-trace: '''
[[Image:Display_Graphs_Traces_29.png|300px|none]]
|This mode displays all window traces of the same type in one graph. In several window types, two multi-trace graphs are displayed in the same window: for example, one for the Real part and one for the imaginary part. In this mode, a''' magnitude gathering mode''' can be activated in the set preferences window: this mode displays signals by creating one area for each Y magnitude included in the window. If two or more signals have the same Y magnitude, they will be displayed in the same area.

This section explains all the functions and information you can find in the graphs, windows and infotrace. It contains also the information relative to the scales, graphic modes, display modes and the contextual menus.


Different windows which contain one or more graphs or traces can be created using the Results dialog or the Add/remove window dialog. You can also add or remove some information in the Infotrace using the Infotrace properties. Manage all the display settings using the right click in almost any area. For each result type there are different available options using the right click.

Window display 2022.JPG

The windows allow to display signal traces. They can contain several traces in the same graph (multi-trace display) or several graphs (multi-graph display). The windows can display 1D graphs (viewmeter, RPM monitoring), 2D graphs (profiles, signal recording) or 3D graphs such as Waterfall display.

Infotrace

The infotrace displays information about the graph:

  • Graph mode: magnitude, real...
  • List of traces with their states: available or not / displayed in all areas or not / not displayed. You can move into the infotrace to select a specified trace and to follow cursor’s value of this trace. Memorized traces are also displayed in the list (Memx)
  • Overall levels: Displays the RMS level in 2D windows containing spectra or time signals.
  • Cursor information: x, y, order, dx, dy if available
  • Marker arrays: Using keyboard arrows, you can select the active trace in the infotrace.

Infotrace 2022.JPG

Traces names

The traces names indicate accurately what signal is displayed. A trace label consists of:

Item Indicates Example
File Trace origin when it does not come from current analysis Measurement A
Source Trace origin when it does not come directly from a plug-in Wtf, Mem02, Oper
Plug-in The plug-in which calculated the trace FFT 1, OCT
Results type The type of result in the plug-in AcgSpct, Coh, Trigger block
Channel The channel in the plug-in [3]
Label The input Label Acc. top
Section The section in the Waterfall Z= 2500 RPM, X=375 RPM
Unit/Weighting Applied alteration Pk-Pk, PSD, (A)
Time Date Of the result 15:50:14 03/10/15

In order to simplify the trace identifications in applications that manage many measurement points (structural dynamics, Roving impact hammer) the content of the front-end identification settings are inserted in the trace labels.

Trace name 2022.JPG

The trace labels display the Component, Node and Direction when the corresponding setting is different from its default value:

  • Component = None
  • Node = 0
  • Direction = Scalar

This applies individually, setting by setting and is independent for each channel.

Contextual menu

The infotrace contextual menu is accessible by right clicking on the infotrace.

Customize: From the Infotrace, right click and select Customize.

Display Graphs Traces 23.png

This dialog box is used to select the information to be displayed in the infotrace (cursor coordinates, marker values…).

All checked items are displayed, unchecked items are not displayed.

  • Select All: Selects all items
  • Unselect All: Unselects all items
  • Ok: Applies the changes and closes the dialog box.
  • Cancel: ignores the changes and closes the dialog box.

Auto width: Sets the Infotrace area width to the width of the largest element currently displayed.

Copy marker table: Copies the marker table content to the clipboard in Excel format, in order to paste it in Excel. Each column/line of the table becomes a column/line in the Excel sheet.

See the "Copy marker" topic p 101 for more details about the marker table copy.

Close: Hides the Infotrace area.

Shaft View

The shaft view or "marguerite" shows the trigger block of FFTs and SOA around one revolution. This graph includes angular cursors (with delta-angle) useful for reading the location of peaks.

Note that in order to provide a stable trace, the corresponding plug-in must be triggered by a keyphasor. This keyphasor (any edge event) being the phase reference of each revolution. In the case of synchronous order analysis, the plug-in is automatically triggered on the tach. pulses.

Display Graphs Traces 109.png

The shaft view shows the first entire revolution contained in the trigger block. If less than one revolution is contained in the trigger block, nothing is displayed. A tachometer must be connect to the FFT or SOA plug-in in order to show traces in the shaft view.

The rotation indicator (and the angle labels arrangement 0 to 360°) is defined by the user’s preferences or directly from the window’s properties.

The keyphasor location is also user definable: It may take place every 45° along the complete revolution.

All graphs in a window have the same rotation and keyphasor location.

Waterfall graphs (2D view, 3D view, color spectrum)
Slices sorting selection in 2D/3D

NVGate is able to display unwrapped run-up/down profiles The "Sort points" selection allows displaying the data along one X scale but sort it along another reference.

The following example shows data displayed with tachometer speed on the X axis speed but sorted along to the time:

V10 release 29.png

This is useful for mixed run up/down to see hysteresis.

Second X axis in profiles
V10 release 30.png


For applications with mixed run-Up/Down (RPM, Torque, Temperature, etc...), it is useful to see the results evolution according to their occurrence (time, slice) but keeping the up/down information. This feature allows viewing the data unwrapped.

Waterfall display features different type of view of the stacked results. All views are related to the same 3D space:

Display Graphs Traces 112.gif

The Z-axis is the selected reference (RPM, time or number of slices in order of the acquisition) its range is the waterfall depth. You can change the reference for z-axis at any time. This is available for 2D and 3D view.

The Y-axis is the selected magnitude; this can be changed at any time.

The X-axis is the frequency.

Tachometer centered on FFT/SOA blocks

This allows centering tachometer speed at the center of the FFT/SOA trigger block(s). It is useful with long trigger blocks (High resolution analyses) to perfectly match the actual data with the order cursor or section.

With classical tach:

The RPM is collected at the end of the analysis block.

Display Graphs Traces 113.png

This situation leads to an offset in the waterfall calculation of the orders (cursors, sections). For a run up, as the angular speed is over evaluated, the order calculation is lower than the actual ones.

With centered tach:

The RPM is calculated as the average speed during the block duration to be synchronized with the analyzed data.

Display Graphs Traces 114.png


With the centered tachometer, the orders calculations match more accurately the actual orders in waterfall.

The computation of the angular speed takes in account the averaging, triggering and overlap used in the plug-in.

The centered speed is calculated as:

Display Graphs Traces 115.png

The RPM centering and averaging is done in the analysis plug-in prior to be connected to the waterfall. To use the centered tach simply add the said tachometer to the corresponding plug-in (FFTn or SOAn). These additional tachometers are available in the waterfall as soon as one of the result of the plug-in is added to the waterfall.

1. Add Tach to the Plug-in,

2. Add plug-in results (Spectra, orders, etc..) to the waterfall,

3. Display the waterfall

  • SOA x: Raw Orbit, Synthetized Orbit (For customer with ORD-Diag option)

Note :

Display Graphs Traces 122.png

The Raw Orbit graph displays an entire number of complete rotations contained in one block. At least one rotation is required.

The FFT should better be triggered by the Ext. Sync. channel.

If the FFT is bad configured, it is possible that no results are shown.
The FFT synthtetized Orbit is only available for customer with FFt-CBT option. The FFT synthetized Orbit is filtered using CBT technics. this method provide a non accurate phase value on synthetiseed orbit. For acurate synthetize Orbit phase, you need to use the SOA Synthetized Orbit.


The ORD Synthesized Orbit graph is calculated with the orders of two channels selected. For a couple "ChannelA, ChannelB" up to 8 Synthesized Orbits can be selected. Each orbit corresponds to an order which appears in the tracked order setting.

The display of the Synthesized Orbit is done on 360 points (1 point per degree).

By using an operator on an active trace and his associated memorized traces is available by right-clicking on the graphs and selecting ’operators’. This operator will be automatically updated if a memorized trace is added or deleted (see also operators).

During a multi-run, the average on automatic memorized trace is done automatically for each run, and the average trace is automatically updated.

Auto scale Y on all

Sets min and max values of the Y scale to the Y min and max values of all signals displayed in the graph. A margin is added to these values to facilitate visibility. The Y width is always more than Y active signal precision.

Cascade view

Present the current active trace in a cascade view of the last 50 (default value) recovered results.

This is dedicated for monitoring used, this is not a waterfall (acquisition mode in real-time). The Z-axis represents the number of slices independently from any reference such as time or RPM evolution.

This function is available only for 2D spectra and trigger blocks.

Warning: if you are in manual trigger, or if there is an absence in the time, you won’t be able to notice it with the cascade view. In the following example, a pause has been made during the measurement; on the waterfall 3Dview (with time for reference) it is possible to see this pause. In the cascade view the pause won’t be noticed (number of block for reference).
