Echogram: Lines page
The Lines page in the Echogram dialog box allows you to control the horizontal and vertical lines used in the echogram presentation. You can make the bottom easier to see, and add lines that hold additional information. The vertical scale of the echogram presentation can be changed. If you wish to add annotations to your echogram, these are enabled on this page.
How to open
This dialog box is opened from the Active menu.

Description
The settings on the Lines page are all related to visual appearance. The setting(s) you choose will only be valid for the currently active echogram. Click in any echogram view to make it active. The active echogram view is identified with a thicker border. Select Apply to All if you wish to use the chosen settings on all the echograms of the same type.
Details
Scale
When enabled, equidistant horizontal scale lines are drawn inside the view in the current foreground colour; black during day and white during night. A maximum of 10 scale lines can be selected. No scale lines are drawn when the scale line count is set to 0 (zero).
Vertical
These options control vertical markers and annotations.
•  Ticks
This function places short vertical markers on the top of the echogram. These lines are used to measure time or distance.
–  None: No vertical markers are shown.
–  Time: A short vertical line is drawn in the upper part of the echogram once every minute.
–  Distance: A short vertical line is drawn in the upper part of the echogram once every specified number of nautical miles.
Annotations
Select Text or Line to allow annotation markers to be shown. If you select Line, each text annotation is followed by a vertical line for improved visibility. Annotations can be typed in manually, set up for automatic generation, or imported from an external device.
Tip
Use the Annotations page to type comments and insert annotations into views. Several different annotation types may be added to the echograms or other views. The Annotations page is located in the Installation dialog box.
When you save raw data, the annotations you have defined are stored as annotation datagrams.
