Trait charts::BarDatum

pub trait BarDatum {
    fn get_category(&self) -> String;
    fn get_value(&self) -> f32;
    fn get_key(&self) -> String;
}

A trait that defines interaction with a data point used in a bar chart. This provides greater flexibility in using different data sources as one can simply implement this trait and be able to use that data in a bar chart.

Required methods

fn get_category(&self) -> String

Return the category of the datum.

fn get_value(&self) -> f32

Return the value of the datum.

fn get_key(&self) -> String

Return the key of the datum. This is optional in a simple bar chart (just return an empty string), but is required in a stacked bar chart as the stacked entries are differentiated by the key.
