Alongtrack Display page
The Alongtrack Display page of the Variable Properties dialog box is used to control the way data is displayed for the alongtrack display of an Sv variable.
To display an along track cruise track, on the Filesets window, select an Sv variable, configure a display grid and select Cruisetrack. Or use View menu, Cruise Track, Acoustic Variable and set a grid for the Alongtrack variable.
Default and Custom properties for thickness and colors on map based windows are available on the Cruisetrack Display page of the EV File Properties dialog box.

Color scheme |
Choose from pre-defined or customized color schemes. User-defined color schemes can be created and edited with the Echocolor application supplied with Echoview. Note that if you add, remove or change the color-scheme files in this folder you will need to restart Echoview before those changes take effect. The grid color is determined by the alongtrack color scheme. Except in the case where it is overriden by the Custom, Grid color settings on the Cruisetrack Display page of the EV File Properties dialog box. Note: If a user created custom color scheme has the same name as a predefined color scheme, its name will have " (.evc file)" appended to it to denote this. See About color schemes for further information. |
Note: The three cruise track color settings are only available for some analysis variables. Alongtrack displays of Mean Sv, Minimum Sv, and Maximum Sv are displayed with the Echogram color settings. Alongtrack displays of ping status display the user-defined colors.
