Struct Chart 

pub struct Chart<'a, LX, LY>
where
    LX: AsRef<str> + 'a,
    LY: AsRef<str> + 'a,
{ /* private fields */ }

A widget to plot one or more dataset in a cartesian coordinate system

Examples

Chart::default()
    .block(Block::default().title("Chart"))
    .x_axis(Axis::default()
        .title("X Axis")
        .title_style(Style::default().fg(Color::Red))
        .style(Style::default().fg(Color::White))
        .bounds([0.0, 10.0])
        .labels(&["0.0", "5.0", "10.0"]))
    .y_axis(Axis::default()
        .title("Y Axis")
        .title_style(Style::default().fg(Color::Red))
        .style(Style::default().fg(Color::White))
        .bounds([0.0, 10.0])
        .labels(&["0.0", "5.0", "10.0"]))
    .datasets(&[Dataset::default()
                    .name("data1")
                    .marker(Marker::Dot)
                    .graph_type(GraphType::Scatter)
                    .style(Style::default().fg(Color::Cyan))
                    .data(&[(0.0, 5.0), (1.0, 6.0), (1.5, 6.434)]),
                Dataset::default()
                    .name("data2")
                    .marker(Marker::Braille)
                    .graph_type(GraphType::Line)
                    .style(Style::default().fg(Color::Magenta))
                    .data(&[(4.0, 5.0), (5.0, 8.0), (7.66, 13.5)])]);

Implementations

impl<'a, LX, LY> Chart<'a, LX, LY>

where LX: AsRef<str>, LY: AsRef<str>,

pub fn block(self, block: Block<'a>) -> Chart<'a, LX, LY>

pub fn style(self, style: Style) -> Chart<'a, LX, LY>

pub fn x_axis(self, axis: Axis<'a, LX>) -> Chart<'a, LX, LY>

pub fn y_axis(self, axis: Axis<'a, LY>) -> Chart<'a, LX, LY>

pub fn datasets(self, datasets: &'a [Dataset<'a>]) -> Chart<'a, LX, LY>

pub fn hidden_legend_constraints( self, constraints: (Constraint, Constraint), ) -> Chart<'a, LX, LY>

Set the constraints used to determine whether the legend should be shown or not.

Examples

let constraints = (
    Constraint::Ratio(1, 3),
    Constraint::Ratio(1, 4)
);
// Hide the legend when either its width is greater than 33% of the total widget width
// or if its height is greater than 25% of the total widget height.
let _chart: Chart<String, String> = Chart::default()
    .hidden_legend_constraints(constraints);

Trait Implementations

impl<'a, LX, LY> Default for Chart<'a, LX, LY>

where LX: AsRef<str>, LY: AsRef<str>,

fn default() -> Chart<'a, LX, LY>

Returns the “default value” for a type.

impl<'a, LX, LY> Widget for Chart<'a, LX, LY>

where LX: AsRef<str>, LY: AsRef<str>,

fn render(self, area: Rect, buf: &mut Buffer)

Draws the current state of the widget in the given buffer. That the only method required to implement a custom widget.
