Struct IsolineChart 

pub struct IsolineChart { /* private fields */ }

Isoline chart builder (unfilled contour lines).

Implementations

impl IsolineChart

pub fn x(self, values: &[f64]) -> Self

Set custom x axis values.

Values must be strictly monotonically increasing. Length must match grid_width.

pub fn y(self, values: &[f64]) -> Self

Set custom y axis values.

Values must be strictly monotonically increasing. Length must match grid_height.

pub fn x_scale(self, scale: ScaleType) -> Self

Set x-axis scale type.

pub fn y_scale(self, scale: ScaleType) -> Self

Set y-axis scale type.

pub fn levels(self, levels: Vec<f64>) -> Self

Set level values for isolines.

Each level generates one contour line. If not set, auto-generates 10 evenly spaced levels.

pub fn color(self, hex: u32) -> Self

Set line color as 24-bit RGB hex value (format: 0xRRGGBB).

pub fn stroke_width(self, width: f32) -> Self

Set line stroke width in pixels.

pub fn opacity(self, opacity: f32) -> Self

Set line opacity (0.0 - 1.0).

pub fn title(self, title: impl Into<String>) -> Self

Set chart title (rendered at top of chart).

pub fn size(self, width: f32, height: f32) -> Self

Set chart dimensions.

pub fn build(self) -> Result<impl IntoElement, ChartError>

Build and validate the chart, returning renderable element.
