pub struct DerivedColorMap<ColorType> { /* private fields */ }
Expand description
This struct is used to dynamically construct colormaps by giving it a slice of colors. It can then be used when being intantiated, but not with associated functions.
use plotters::prelude::{BLACK,BLUE,WHITE,DerivedColorMap,ColorMap};
let derived_colormap = DerivedColorMap::new(
&[BLACK,
BLUE,
WHITE]
);
assert_eq!(derived_colormap.get_color(0.0), BLACK);
assert_eq!(derived_colormap.get_color(0.5), BLUE);
assert_eq!(derived_colormap.get_color(1.0), WHITE);
Implementations§
source§impl<ColorType: Color + Clone> DerivedColorMap<ColorType>
impl<ColorType: Color + Clone> DerivedColorMap<ColorType>
sourcepub fn new(colors: &[ColorType]) -> Self
pub fn new(colors: &[ColorType]) -> Self
This function lets the user define a new colormap by simply specifying colors in the correct order. For calculation of the color values, the colors will be spaced evenly apart.

&self,

) -> HSLColor
fn get_color_normalized( &self, h: FloatType, min: FloatType, max: FloatType ) -> HSLColor
A slight abstraction over get_color function where lower and upper bound can be specified.
source§fn get_color(&self, h: FloatType) -> ColorType
fn get_color(&self, h: FloatType) -> ColorType
Takes a scalar value 0.0 <= h <= 1.0 and returns the corresponding color.
Typically color-scales are named according to which color-type they return.
To use upper and lower bounds with ths function see get_color_normalized.
