Customizing the Display of Data
Echograms
Echograms are a representation of what is detected by the sensors with the acoustic signals.

Display Configuration
Read this section to know how data are displayed on Scala2 and how to change their display.
- Control Panels
- Customization Panels
  The customization panels contain customization options for the data.
- Receiver Data
- Using the Virtual Charger Room
  You can display the fleet of sensors in Scala2 Virtual Charger Room, when sensors are connected to the Dock or trawling.
- Creating Data Pages
- Managing Windows
- Customizing the Display of Data
  - Echograms
    Echograms are a representation of what is detected by the sensors with the acoustic signals.
    - Displaying an Echogram
      You can display an echogram view on a page.
    - Echogram Display Settings
      You can apply different display settings to the echogram.
    - About the Echogram Display
    - Changing the Echogram Colors
      You can change the default colors of the echogram. The ability to configure the color palettes is interesting to highlight specific things, for example to clearly distinguish the sea bottom from fish targets.
    - Displaying the View from Surface to Seabed
      You can choose to display the echogram beginning from the water surface instead of the default view from the sensor position. Depending on the type of fishery, this is useful to see the trawl descent from the sea surface to the seabed.
    - Displaying Echograms of Seine Sensors
      You can display an echogram image of the contents of a seine purse when using a Seine sensor with side-looking option.
    - Displaying the Bottom Line
      You can display lines on an echogram to mark the bottom of the trawl and the beginning of the seabed.
    - Changing the Distance from the Door Sounder to the Bottom
      You can change the distance at which the Door Sounder echogram begins.
    - Adding a Range Marker
      You can set a range marker at a given depth, for example if you need to ensure that your trawl net stays at this depth. It is called a Variable Range Marker (VRM).
  - Zooming on Timestamp and Distance Scale
    In echograms and history plots, you can zoom in and out on the distance scale and timestamp and move them along.
  - Sensor Numerical Data
    Data such pitch and roll, temperature, depth can be displayed in dials, gauges, history plots or text format.
  - 3D Views
    You can display 3D views of different elements from the system, for example the trawl doors or trawl speed sensors.
  - Displaying the Chart View
    You can display the location and trajectory of the trawl behind the vessel if you receive GPS data and have door positioning sensors.
  - Displaying a Position Marker
    You can place a marker on plots and echograms to display the GPS position at a given time on the timestamp.
- Setting an Alarm on Incoming Data
  You can be alerted by an alarm when data received have a given value.
- Changing the Default Units
  You can change the default units of data displayed in Scala2.
- Recording and Replaying Data
  Data received by Scala2 can be replayed with ScalaReplay2 application.

Displaying an Echogram

You can display an echogram view on a page.

Before you begin

You must be in Customize mode to do this task.

Procedure

Open the drawer on the right side of the screen to display the control panels.
In the control panels, click the Mx tab. Under the sensor's name, click then drag Sonar Data to a page, where a yellow area appears.

Tip: You can change the source of an existing echogram by dragging the sonar data of another sensor above it.
If the sensor has been configured with more than one sounding direction, click the direction displayed next to the sensor name and select another one.

Note: Refer to the sensors' manuals to have more information about the configuration of the sounding mode.
On the echogram, click the wheel icon next to the name of the sensor to open the display settings. This menu allows to change settings such as the depth scale, color palette, or viewing mode. See Echogram Display Settings for more details.

For example, if you are doing bottom trawling: switch to the Bottom Expansion viewing mode to display a more precise view of the bottom and better see fish close to the bottom. This view is usually used with echosounders on the hull, but you can use it with NBTE sensors on the trawl if the reception is good and the bottom is correctly detected.

What to do next

Deactivate the Customize mode when you have finished customizing pages: click Menu
