(categorical-domain? dom)True if domain is a sequence of non-numeric values (categorical).
True if domain is a sequence of non-numeric values (categorical).
(format-log-ticks ticks)Format log scale tick values. Values are always clean 1-2-3-5 multiples of powers of 10, so formatting is straightforward: integers >= 1 shown without decimals, sub-1 values use minimal decimal places.

(format-ticks sx ticks)Format tick values: integers shown without decimals, floats rounded to the precision implied by the tick step size (avoids floating-point noise like 0.30000000000000004). Falls back to wadogo formatting only when the step cannot be determined (< 2 ticks).

(log-ticks [lo hi] n)Generate clean log-scale tick values for a [lo hi] domain, targeting approximately n ticks. Uses ggplot2-style 1-2-5 nice numbers instead of wadogo's linear-in-log-space approach (which produces irrational values like 3.162...). Returns a vector of tick values (doubles).
Strategy:
Generate clean log-scale tick values for a [lo hi] domain, targeting approximately n ticks. Uses ggplot2-style 1-2-5 nice numbers instead of wadogo's linear-in-log-space approach (which produces irrational values like 3.162...). Returns a vector of tick values (doubles). Strategy: - Powers of 10 only when they give >= 3 ticks (strongly preferred) - 1-2-5 intermediates per decade when more ticks are needed - 1-2-3-5 intermediates for dense sub-decade ranges - Bounding powers of 10 are included when they fall within a small margin (15% of log-span) of the domain edges
Create a wadogo scale mapping domain values to a pixel range.

(pad-domain [lo hi] scale-spec)Add padding to a numeric domain. When lo == hi (constant data), pads by ±1 or ±5% of |lo|, whichever is larger.

(scale-kind domain scale-spec)Determine the wadogo scale type (:categorical, :log, or :linear) from domain and spec. Passes through vector dispatch values like [:linear :doc] for doc defmethods.
