isogonal
A line drawn on a map or a chart joining points of equal variation (magnetic declination). On aeronautical charts, isogonic lines appear as irregular dashed lines (−3° E), and their values also are indicated alongside the lines. The annual change in their values is indicated at the bottom of the chart. Also called an isogonic lines.
