Single target angles graph
The Angles graph is available for single target echograms and displays a scatter plot of the minor-axis angle vs. the major-axis angle for each single target in a selection or region.
To display an angles graph for a selection:
- Make a selection.
- On the Shortcut (right-click) menu, point to Graph selection, and then click Angles.
To display an angles graph for a region:
- Select an existing region or define a new region.
Note: If you wish to graph a bad data region, you must clear the Exclude bad regions option on the Analysis page of the Variable Properties dialog box.
- On the Shortcut (right-click) menu, point to Graph selection, and then click Angles.
See About Beam Geometry for a brief description of angles in Echoview.
Note: Linking this graph to an extending selection, could cause performance problems.
Legend
- Each target is displayed in the same color with which it is displayed on the single targets echogram. That is, the color conveys the target strength of the target according the selected color scheme.
- Fish tracks are displayed by connecting single target squares with a line of the same color as the region which defines the track on the underlying single targets echogram. These are randomly assigned.
- The first target in a fish track is displayed as a triangle pointing upwards.
- The last target in a fish track is displayed as a triangle pointing downwards.
