Enum gnuplot::PaletteType

pub enum PaletteType {
    Gray(f32),
    Formula(i32, i32, i32),
    CubeHelix(f32, f32, f32, f32),
    Custom(Vec<(f32, f32, f32, f32)>),
}

Specifies what sort of palette to use

Variants

Gray(f32)

Use a gray palette with a specified gamma

Formula(i32, i32, i32)

Use a palette with that uses a predefined formula for each color component. Each formula is identified by an integer between [-36, 36]. See gnuplot documentation, or use the pre-defined constants.

CubeHelix(f32, f32, f32, f32)

Use a cube helix palette, with a certain start (in radians), cycles, saturation and gamma.

Custom(Vec<(f32, f32, f32, f32)>)

A custom palette is specified by a sequence of 4-tuples (with at least one element). The first element is the grayscale value that is mapped to the remaining three elements which specify the red, green and blue components of the color. The grayscale values must be non-decreasing. All values must range from 0 to 1.

Trait Implementations

impl Clone for PaletteType

fn clone(&self) -> PaletteType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PaletteType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<PaletteType> for PaletteType

fn eq(&self, other: &PaletteType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<PaletteType> for PaletteType

fn partial_cmp(&self, other: &PaletteType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
