Customizing the Display of Data
Sensor Numerical Data
Data such pitch and roll, temperature, depth can be displayed in dials, gauges, history plots or text format.
Display Types
You can choose between different types of display when you drag numerical data to a page.

- Customizing the Display of Data
  - Echograms
    Echograms are a representation of what is detected by the sensors with the acoustic signals.
  - 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.
    - Display Types
      You can choose between different types of display when you drag numerical data to a page.
    - Changing the Display of Page Elements
      You can change the title, font, unit of measure and arrangement of data displayed on pages.
    - Displaying Catch Monitoring
      You can be alerted when the codend is full.
    - Displaying Single Trawl Spread
      If you have a trawl with door sensors, you can display a plot to see the distance between the trawl doors. For twin trawls, you can also see the distance between both doors and the clump.
    - Displaying Twin Trawl Spread
      You can display a diagram of twin trawl spread in order to see the distance between the port and starboard doors, and between the clump and port/starboard doors. This way, if the trawl is asymmetric you can adjust accordingly and see live results very easily.
  - 3D Views
    You can display 3D views of different elements from the system, for example the trawl doors or trawl speed 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 Scala.
- Recording and Replaying Data
  Data received by Scala can be replayed with Scala Replay application.

Label

There are also dials specific to certain types of data:


Name	Types of data	Illustration	Display details
Horizon	Pitch Roll		Displays horizon line according to pitch and roll. Red dot in the middle indicates pitch angle and red arrow on top indicates roll angle.
Wind dial	True wind speed True wind direction True wind angle Apparent wind angle Apparent wind speed		Vessel is displayed in the middle in grey. Apparent wind angle is displayed in blue and true wind angle in orange.
Heading dial	Heading (True) Heading (Magnetic)		Red arrow displays North. Cardinal points are displayed around.
Trawl Speed Dial	For trawl speed type sensors: Water speed along Water speed across		Leeway angle is displayed for port (P) or starboard (S).
Water Speed (WS) Dial	For speed log type of device, data received from NMEA inputs: Water speed along Water speed across		Leeway angle is displayed for port (P) or starboard (S). Vessel is displayed in the middle in grey.
