Struct StackLayout 

pub struct StackLayout { /* private fields */ }

Computes stacked layout from grouped data. Equivalent to D3’s d3.stack().

Implementations

impl StackLayout

pub fn new() -> Self

Create a new StackLayout with default settings (StackOrder::None, StackOffset::None).

pub fn order(self, order: StackOrder) -> Self

Set the stacking order.

pub fn offset(self, offset: StackOffset) -> Self

Set the stacking offset.

pub fn layout( &self, keys: &[String], series_names: &[String], values: &[Vec<f64>], ) -> Vec<StackedPoint>

Compute stacked layout.

Arguments

• keys: the categories (x-axis values), e.g., [“Jan”, “Feb”, “Mar”]
• series_names: the series (stacking groups), e.g., [“Hardware”, “Software”, “Services”]
• values: a 2D structure where values[series_index][key_index] = the value (outer = series, inner = keys)

Returns

A Vec<StackedPoint> for every (key, series) combination.

Trait Implementations

impl Default for StackLayout

fn default() -> Self

Returns the “default value” for a type.
