Availability

2D projections graphs

Available for a region or selection on a single target echogram.

Notes:

  • A set of four graph windows can be opened or you can choose to open individual graph window at separate times.
  • Single target graphs allow you remove and add targets from fish track regions.
  • Graphed points are displayed in the single target color.

3D single target graph

Available for a region or selection on a single target echogram - single targets are displayed in 3D.

Angles graph

Available for a region or selection on a single target echogram.

Notes:

  • Single target graphs allow you remove and add targets from fish track regions.
  • Graphed points are displayed in the single target color.

Beam graph

Available for a single beam on a single sector plot.

Bottom classification graph

Available for a Bottom points variable after a bottom classification. Bottom features may be specified for the X and Y axis. The color of a point represents an assigned bottom class.

Frequency Distribution graph

Available for a region or selection on an echogram.

Frequency Response graph

Available for a region or selection on an Sv echogram and displays NASC/NASC(ref) for specified Sv variables.

Heading graph

Available for a heading variable.

Line graph

Available for a line variable. A line can represent sounder-detected bottom detections, a heave source line, altitude, bottom picks or combinations of line data.

Ping graph

Available for a single ping or a set of pings contained in a selection made using the Vertical band selection tool.

Pitch graph

Available for a pitch variable.

Relative mean dB graph

Available for a region or selection on an Sv or unspecified dB echogram.

Roll graph

Available for a roll variable.

Wideband Frequency Response graph

Available for a selection or region on a pulse compressed wideband echogram. Displays the frequency spectrum of selected Sv or TS samples or single targets.

See also: Factors that can degrade the wideband frequncy response.

Target Length vs Depth graph

Available for a region or selection on a target length echogram.

Note: Graphed points are displayed in the single target color.

Threshold Response graph

Available for a region or selection on an Sv echogram.

TS vs Depth graph

Available for a region or selection on a single target echogram.

Note: Graphed points are displayed in the single target color.
