Struct PlotData 

pub struct PlotData {
    pub spec: PlotSpec,
    pub points: Vec<(f32, f32)>,
    pub x_range: (f32, f32),
    pub y_range: (f32, f32),
    pub warnings: Vec<String>,
}

Prepared data for rendering a plot (frontend-agnostic).

This intermediate representation separates data extraction from rendering, allowing different frontends (TUI, GUI) to use the same data preparation logic.

Fields

spec: PlotSpec

The original plot specification.

points: Vec<(f32, f32)>

Data points as (x, y) pairs.

x_range: (f32, f32)

X-axis range (min, max).

y_range: (f32, f32)

Y-axis range (min, max).

warnings: Vec<String>

Warnings about data quality (e.g., skipped non-numeric cells).

Implementations

impl PlotData

pub fn from_spec<F>(spec: &PlotSpec, cell_value: F) -> Result<Self, String>

where F: FnMut(usize, usize) -> Option<f64>,

Extract plot data from a spec using a cell value accessor.

The cell_value closure takes (row, col) and returns the numeric value at that position, or None if the cell is empty or non-numeric.

Trait Implementations

impl Clone for PlotData

fn clone(&self) -> PlotData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlotData

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

Formats the value using the given formatter.
