Customizing the Display of Data
Echograms
Echograms are a representation of what is detected by the sensors with the acoustic signals.
Echogram Display Settings
You can apply different display settings to the echogram.

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.

Echogram Display Settings

You can apply different display settings to the echogram.

On the echogram, click the wheel icon next to the name of the sensor to open the display settings.


Filtered Data	Activated by default. The system applies filters to data to smooth the measures received.
Show Palettes	Changes the default colors of the echogram. See Changing the Echogram Colors for more details.
Vertical Display	Suited for Seine Explorer with side-looking sounding.
Fixed beam Width	Changes the method of displaying the echogram. Read About the Echogram Display for more information.
Beam Width Correction	This feature should always be activated. It homogenizes the beam widths displayed on the echogram.
Standard Mode	The echogram is displayed beginning from the sensor position.
True Mode	The echogram is displayed beginning from the water surface. See Displaying the View from Surface to Seabed for more details.
Bottom Expansion	Displays a more precise view of the bottom to better see fish close to the bottom.
Show A-Scope / Hide A-Scope	Shown on the right side of the echogram by default. The scope displays the latest received sonar data.
Set VRM	Sets a range marker at a given depth.
Draw Bottom Line	Displays a yellow line at the bottom of the trawl and a white line at the beginning of the seabed.
Thick Bottom Line	Displays a thick white line at the beginning of the seabed.
Z-Scale Synchronization	Synchronizes the depth scale on echograms placed one next to each other horizontally.
Time Synchronization	Synchronizes the time stamp and zoom on echograms and history plots placed one above each other.
Manual Z Scale	Manually adjust the depth scale.
Z Scale Follow Bottom	Keep the zoom you set on the depth scale and follow the bottom to always keep it on the image.
Z Scale Auto Range	Keep the depth value that you set on the top of the scale and adjust the zooming to always keep the bottom on the first third of the image.
Z Scale Follow Sensor	Use with Door Sounder or Door Explorer sensors to keep the view of the door on the echogram. Available only when True Mode is activated.
Vertical Smoothing / Horizontal Smoothing (Expert Mode)	Displays smoother transitions between the colors in the echogram.
