Struct PlotMarks 

pub struct PlotMarks {
    pub line: Marker,
    pub point: Marker,
    pub bar: Marker,
    pub column_eighths: &'static [&'static str; 8],
    pub axis: Set<'static>,
    pub tick_x: &'static str,
    pub tick_y: &'static str,
    pub grid_across: &'static str,
    pub grid_down: &'static str,
}

The marks ratatui’s Chart, Canvas and BarChart draw, and their axis and legend lines; ratatui ignores the locale, so each set names its own.

Fields

line: Marker

A line: an XY line, a density curve, a fit drawn over bars, a dense Q-Q plot.

point: Marker

One mark per point: a scatter, a box plot’s strokes, a sparse Q-Q plot.

bar: Marker

A column from zero up to each point: the XY bar style and the histogram.

column_eighths: &'static [&'static str; 8]

A vertical bar’s top, one to eight eighths of a cell filled from the bottom; the last is a whole cell, the bar’s body.

axis: Set<'static>

The axes and the legend frame.

tick_x: &'static str

A tick on the x axis line and on the y axis line, pointing at its label.

tick_y: &'static str

grid_across: &'static str

The grid: a dotted line across the plot at a y tick, and down it at an x tick.

grid_down: &'static str

Implementations

impl PlotMarks

pub fn column_set(&self) -> Set<'static>

The vertical bars a BarChart draws with.

pub fn is_mark(marker: Marker, symbol: &str) -> bool

Whether a canvas drawing with marker put this symbol in its cell, rather than an axis or a label. Braille’s blank pattern counts: the grid draws it.

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

Redraw ratatui Chart axes and legend frame (always line::NORMAL) in this set’s axis lines, found by shape: the axes are the └ with │ above and an unclosed ─ run to its right; the legend is a closed box. Labels with those characters stay. A chart too small for both axes changes every line cell. A no-op under Unicode.

Trait Implementations

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PlotMarks

impl Debug for PlotMarks

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
