Expand description

Trait for custom price formatting on the Y axis.

Implement this trait to control how numeric prices are displayed as labels. All formatters must be Send + Sync so they can be shared across the render pipeline.

fn format(&self, price: f64) -> String

Format a price value into a display string

§Arguments
  • price - The price value to format
§Returns

Formatted string to display on the price axis

Source

fn clone_box(&self) -> Box<dyn PriceFormatter>

Clone this formatter into a Box

Provided Methods§

Source

fn format_tick(&self, price: f64) -> String

Format a price axis tick. Defaults to format; override it to write ticks differently from crosshair and price tag labels.

Dyn Compatibility§

In older versions of Rust, dyn compatibility was called "object safety".
