PropertyDefaultMeaning
lim[0, 1]Directed domain used to place grid lines
ticks5Target count or explicit values / labeled pairs
intervalAutomaticPositive fixed tick step
stroke-widthem(1/16)Grid thickness, relative to inherited font size
direction"y"Draw horizontal lines; may be overridden

Grid lines at ticks using the count/explicit/interval rules of Axis. lim supplies the generation domain (default [0,1]).

direction="x" draws vertical lines at x values; direction="y" draws horizontal lines at y values. Mesh/HMesh default to x, VMesh to y: H/V names the scale direction. Ambient Graph limits map values. Style lines with stroke, stroke-width, stroke-dasharray, and opacity.
