Structs

LabelStrategyConfig

Configuration for label strategy determination.

TextMetrics

Text-shaping parameters that influence the rendered width of a label.

Enums

LabelStrategy

The strategy selected for rendering labels.

Functions

approximate_text_width

Approximate text width in pixels using a character-width table. Calibrated for ~12px font. For other sizes, use approximate_text_width_at.

approximate_text_width_at

Approximate text width scaled for a specific font size.

compute_skip_factor

After rotation, check if labels still overlap and compute skip factor.

format_tick_value_si

Format a numeric tick value with SI suffixes for large magnitudes. Returns compact labels like “1.5M”, “200K”, “3B” based on the tick step.

measure_text

Measure the rendered width of a text string under the given metrics.

strategic_indices

Select strategic indices for sampled label display. Always includes first and last; evenly distributes the rest.

truncate_label

Truncate a label to fit within max_width, adding ellipsis.

truncate_label_with_metrics

Truncate a label to fit within max_width, adding ellipsis, measuring glyphs under the provided metrics.
