Module format 

Public value and label formatting helpers.

format_value renders a single data Value the way ggplot-rs shows it in hover tooltips (rounded numbers, calendar dates for datetimes). The label_* axis/legend formatters from crate::scale::format are re-exported here so hosts can format numbers consistently with the plot.

Functions

format_timestamp

Format a timestamp (seconds since the Unix epoch, UTC) with the same strftime subset the datetime scales use for their labels — %Y %y %m %-m %b %B %d %-d %e %a %A %H %M %S %% — and the month / weekday names of locale (English without). For hosts that format a date the way an axis would, e.g. in their own tooltips.

format_value

Format one data value for display (tooltips, data labels):

format_value_locale

format_value in the conventions of locale: numbers get its decimal and thousands marks, datetimes its date format and month names.
