Animated current information is available in the chart application<br />
wherever a diamond-shaped symbol with a "C" is displayed:<br />
This symbol identifies the location of a current station and the<br />
availability of current information for the location.<br />
When you select a current station symbol the chart context menu is<br />
displayed, which provides the Animate option.<br />
When you select Animate the animate menu is displayed and the<br />
diamond-shaped current symbols are replaced with dynamic current<br />
arrows which indicate the direction and strength of the currents:<br />
Current animation.<br />
• Arrows indicate the direction of current flows.<br />
• The length of the arrow indicates the flow rate.<br />
• The color of the arrow indicates the flow speed:<br />
– Red: increasing current flow speed.<br />
– Blue: decreasing current flow speed.<br />
The animation can be viewed continuously or incrementally at a<br />
time interval that you specify. You can also set the date for the<br />
animation, and start or restart the animation at any point within a<br />
24-hour period. If the system does not have a valid date and time<br />
the date used will be midday for the system default date.<br />
Note: Not all electronic charts support the animated currents<br />
feature.<br />
