What does a barograph measure?

• A barometer displays the present pressure and the change of pressure since it was last set using a marker hand on the dial.
• A barograph records the history of the pressure on a paper chart, wrapped around a clock-driven drum.
• Underway on a fully crewed vessel, the logbook serves as a detailed record of pressure changes.
• On overnight anchorages, a printed barograph trace is a convenient way to learn how the pressure changed during the night when there was no watch to record it.
