Struct SeriesAnno

pub struct SeriesAnno<'a, DB: DrawingBackend> { /* private fields */ }

The annotations (such as the label of the series, the legend element, etc) When a series is drawn onto a drawing area, an series annotation object is created and a mutable reference is returned.

Implementations

impl<'a, DB: DrawingBackend> SeriesAnno<'a, DB>

pub fn label<L: Into<String>>(&mut self, label: L) -> &mut Self

Set the series label

• label: The string would be use as label for current series

pub fn legend<E: IntoDynElement<'a, DB, BackendCoord>, T: Fn(BackendCoord) -> E + 'a>( &mut self, func: T, ) -> &mut Self

Set the legend element creator function

• func: The function use to create the element Note: The creation function uses a shifted pixel-based coordinate system. And place the point (0,0) to the mid-right point of the shape
