How to understand the tide graph
• Vertical axis: Height, Horizontal axis: Time
• The information is mostly accurate under moderate weather conditions. However,
storms and weather fronts can influence forecasted tide times and heights.
• Drag the time scale at the bottom of the screen sideways then read the tide height
at the selected time (drag to the left to display the future information, right for the
past information).
• To set the time scale to the current time, select the clock mark at the bottom left-
hand corner of the screen. The color of the clock mark turns gold.
• To return to the chart plotter display, select [Close] at the top right-hand corner of
