Struct Contours

pub struct Contours<'a> { /* private fields */ }

Implementations

impl<'a> Contours<'a>

pub fn start(&mut self, start: f64) -> &mut Self

Sets the starting contour level value. Must be less than contours.end

default: null

pub fn end(&mut self, end: f64) -> &mut Self

Sets the end contour level value. Must be more than contours.start

default: null

pub fn size(&mut self, size: f64) -> &mut Self

Sets the step between each contour level. Must be positive.

default: null

pub fn coloring(&mut self, coloring: Coloring) -> &mut Self

Determines the coloring method showing the contour values. If fill, coloring is done evenly between each contour level If lines, coloring is done on the contour lines. If none, no coloring is applied on this trace.

default: fill

pub fn showlines(&mut self, showlines: bool) -> &mut Self

Determines whether or not the contour lines are drawn. Has an effect only if contours.coloring is set to fill.

default: true

pub fn showlabels(&mut self, showlabels: bool) -> &mut Self

Determines whether to label the contour lines with their values.

default: false

pub fn labelfont(&mut self) -> &mut Labelfont<'a>

Sets the font used for labeling the contour levels. The default color comes from the lines, if shown. The default family and size come from layout.font.

pub fn labelformat(&mut self, labelformat: &'a str) -> &mut Self

Sets the contour label formatting rule using d3 formatting mini-language which is very similar to Python, see: https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format

default: ``

pub fn operation(&mut self, operation: Operation) -> &mut Self

Sets the constraint operation. = keeps regions equal to value < and <= keep regions less than value > and >= keep regions greater than value [], (), [), and (] keep regions inside value[0] to value[1] ][, )(, ](, )[ keep regions outside value[0] to value[1]` Open vs. closed intervals make no difference to constraint display, but all versions are allowed for consistency with filter transforms.

default: =

pub fn value(&mut self, value: Any) -> &mut Self

Sets the value or values of the constraint boundary. When operation is set to one of the comparison values (=,<,>=,>,<=) value is expected to be a number. When operation is set to one of the interval values ([],(),[),(],],)(,[) value is expected to be an array of two numbers where the first is the lower bound and the second is the upper bound.

default: 0

Trait Implementations

impl<'a> Default for Contours<'a>

fn default() -> Contours<'a>

impl<'a> Serialize for Contours<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
