FrameTicks

Status: Experimental

present and registered, but lightly documented and not yet covered by dedicated tests.

Description

FrameTicks

is an option for Graphics and Plot that specifies the tick marks on the edges of a frame.

Notes

FrameTicks -\> Automatic (the default) draws major and minor ticks with labels on every drawn frame edge; FrameTicks -\> None keeps the frame box but draws no ticks; the {{left, right}, {bottom, top}} form selects Automatic or None per edge.

Examples (3)

Every input below was run against the current Mathilda build and its output recorded.

Applications (3)

An inert option keyword: it just names the left of a rule

In[1]:= FrameTicks -> None
Out[1]= FrameTicks -> None

Per-edge forms pass through unevaluated too

In[2]:= FrameTicks -> {Automatic, None}
Out[2]= FrameTicks -> {Automatic, None}

Accepted by Plot, which builds a Graphics

In[3]:= Head[Plot[Sin[x], {x, 0, 3}, FrameTicks -> None]]
Out[3]= Graphics

Implementation notes

Definition. FrameTicks is an option for Graphics and Plot that specifies the tick marks on the edges of a frame. FrameTicks -> Automatic (the default) draws major and minor ticks with labels on every drawn frame edge; FrameTicks -> None keeps the frame box but draws no ticks; the {{left, right}, {bottom, top}} form selects Automatic or None per edge. It is an inert option keyword — no builtin and no value of its own (it carries no attributes), declared with its docstring in info.c.

Representation. A bare EXPR_SYMBOL. It is read as the left of a FrameTicks -> value rule by the 2D renderer in src/graphics/render.c: the option loop matches name == SYM_FrameTicks and interprets the value — Automatic/True turns ticks on for every drawn edge, None/False keeps the frame box but suppresses ticks and labels, and a {{l, r}, {b, t}} nesting is read per edge.

Usage & limits. Meaningful only inside a Graphics/Plot call that draws a frame; with Frame -> False there are no frame edges to tick. The symbol itself performs no computation — all behaviour is in the renderer's reading of the rule.

Attributes: none registered.

Notes

FrameTicks is an option for Graphics and Plot controlling the tick marks on a frame's edges: Automatic (the default) draws labelled major and minor ticks on every drawn edge, None keeps the frame box but no ticks, and a {{left, right}, {bottom, top}} form selects Automatic or None per edge. It is an inert keyword with no value of its own; all behaviour lives in the 2D renderer's reading of the FrameTicks -> value rule. It only bites when a frame is actually drawn.
