The tide curve shows as a shaded area, where higher tides are taller
(blue) and lower tides are shorter (red). The solid, horizontal line
(with the current tide box on the left) indicates the current tide
height. The figure to the left of the line shows the current tide level
in feet. The Mean Lower Low Water (MLLW) appears as a solid,
horizontal line near the bottom of the chart (This line only appears
if the tide ranges to the zero value or below). The numbers directly
below/above LCL and STA indicate the maximum/minimum levels,
respectively. The four data fields below the chart, indicate event
times and levels the tide changes starting in the upper left field,
going downward, then to the upper right and down again.
