Struct vega_lite_4::BinParamsBuilder

pub struct BinParamsBuilder { /* fields omitted */ }

Builder for BinParams.

Implementations

impl BinParamsBuilder

pub fn anchor<VALUE: Into<f64>>(&mut self, value: VALUE) -> &mut Self

A value in the binned domain at which to anchor the bins, shifting the bin boundaries if necessary to ensure that a boundary aligns with the anchor value.

Default value: the minimum bin extent value

pub fn base<VALUE: Into<f64>>(&mut self, value: VALUE) -> &mut Self

The number base to use for automatic bin determination (default is base 10).

Default value: 10

pub fn binned<VALUE: Into<bool>>(&mut self, value: VALUE) -> &mut Self

When set to true, Vega-Lite treats the input data as already binned.

pub fn divide<VALUE: Into<Vec<f64>>>(&mut self, value: VALUE) -> &mut Self

Scale factors indicating allowable subdivisions. The default value is [5, 2], which indicates that for base 10 numbers (the default base), the method may consider dividing bin sizes by 5 and/or 2. For example, for an initial step size of 10, the method can check if bin sizes of 2 (= 10/5), 5 (= 10/2), or 1 (= 10/(5*2)) might also satisfy the given constraints.

Default value: [5, 2]

pub fn extent<VALUE: Into<BinExtent>>(&mut self, value: VALUE) -> &mut Self

A two-element ([min, max]) array indicating the range of desired bin values.

pub fn maxbins<VALUE: Into<f64>>(&mut self, value: VALUE) -> &mut Self

Maximum number of bins.

Default value: 6 for row, column and shape channels; 10 for other channels

pub fn minstep<VALUE: Into<f64>>(&mut self, value: VALUE) -> &mut Self

A minimum allowable step size (particularly useful for integer values).

pub fn nice<VALUE: Into<bool>>(&mut self, value: VALUE) -> &mut Self

If true, attempts to make the bin boundaries use human-friendly boundaries, such as multiples of ten.

Default value: true

pub fn step<VALUE: Into<f64>>(&mut self, value: VALUE) -> &mut Self

An exact step size to use between bins.

Note: If provided, options such as maxbins will be ignored.

pub fn steps<VALUE: Into<Vec<f64>>>(&mut self, value: VALUE) -> &mut Self

An array of allowable step sizes to choose from.

pub fn build(&self) -> Result<BinParams, String>

Builds a new BinParams.

Errors

If a required field has not been initialized.
