Struct Config 

pub struct Config {
    pub chart_area: ChartArea,
    pub top_x: AxisOptions,
    pub bottom_x: AxisOptions,
    pub left_y: AxisOptions,
    pub right_y: AxisOptions,
    pub chart_title: ChartTitleOptions,
    pub grid: GridOptions,
    pub legend: Legend,
    pub picked_points: Option<PickedPointsConfig>,
    pub picked_data: Option<DataSelectionsConfig>,

}

Fields

chart_area: ChartArea

top_x: AxisOptions

bottom_x: AxisOptions

left_y: AxisOptions

right_y: AxisOptions

chart_title: ChartTitleOptions

grid: GridOptions

legend: Legend

picked_points: Option<PickedPointsConfig>

picked_data: Option<DataSelectionsConfig>

Typed point/bin/cell/contour selections. Additive to the legacy picked_points field so existing documents and hosts keep their exact point-only contract.

colorbar: Option<ColorBarOptions>

The colourbar and, with it, the chart’s z scale. None (key absent in JSON) is a chart with no z dimension — the shape of every document written before field series existed.

draw_style: DrawStyle

Chart-global render style. Precise (default, key absent in JSON) is identical to current rendering; every other variant is an opt-in stylized mode. No per-series mixing.

Implementations

impl Config

pub fn scaled(&self, scale: f32) -> Self

Multiply every pixel-based visual dim by scale. Data ranges, colors, and scale enums are untouched. For resolution-invariant high-DPI export.

pub fn scale_in_place(&mut self, s: f32)

impl Config

pub fn auto_significant_digits_all(&mut self)

impl Config

pub fn fit_to_data_area( &mut self, target: DataArea, strategy: FitStrategy, ) -> Result<(), LayoutError>

pub fn resize_chart_area( &mut self, new_area: ChartArea, ) -> Result<(), LayoutError>

pub fn resize_chart_area_scaled( &mut self, new_area: ChartArea, ) -> Result<(), LayoutError>

pub fn set_side_margin( &mut self, side: Side, value: f32, ) -> Result<(), LayoutError>

pub fn set_margins( &mut self, margins: Margins, strategy: FitStrategy, ) -> Result<(), LayoutError>

impl Config

pub fn nudge(&mut self, element: Element, dx: f32, dy: f32) -> NudgeResult

Apply a measurement-free approximate containment policy. Text-bearing elements use representative anchors here; exact glyph bounds are kept in the Selectable path and no text measurer is required by nudge.

pub fn nudge_x(&mut self, element: Element, dx: f32) -> NudgeResult

pub fn nudge_y(&mut self, element: Element, dy: f32) -> NudgeResult

impl Config

pub fn margins(&self) -> Margins

pub fn data_area(&self) -> Result<DataArea, LayoutError>

pub fn colorbar_band(&self, side: &Side) -> f32

How far this side’s axis band is pushed in from the chart-area edge by the colourbar band. Zero on the three sides the bar is not on, and when it is hidden.

Public because everything that positions chrome against the chart edge — the axis title’s placement, its hit box, its nudge anchor — needs the same number, and computing it separately in each is how they drift apart.

pub fn validate(&self) -> Result<(), LayoutError>

impl Config

pub fn apply_axis_preset(&mut self, preset: AxisPreset)

Apply preset to all four axes at once. See AxisPreset for what is (and is not) touched.

impl Config

pub fn auto_ticks_all( &mut self, top_x: (f64, f64), bottom_x: (f64, f64), left_y: (f64, f64), right_y: (f64, f64), target_count: usize, ) -> Result<(), TickError>

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
