format property

String? format
getter/setter pair

A format string for the axis label. The context is available as format string variables. For example, you can use {text} to insert the default formatted text. The recommended way of adding units for the label is using text, for example {text} km.

To add custom numeric or datetime formatting, use {value} with formatting, for example {value:.1f} or {value:%Y-%m-%d}.

See format string for more examples of formatting.

The default value is not specified due to the dynamic nature of the default implementation.
