Struct plotters::prelude::GroupBy

pub struct GroupBy<T>(_, _)
 where
    T::ValueType: PrimInt + ToPrimitive + FromPrimitive + Mul,
    T: Ranged;

The ranged value spec that needs to be grouped. This is useful, for example, when we have an X axis is a integer and denotes days. And we are expecting the tick mark denotes weeks, in this way we can make the range spec grouping by 7 elements.

Trait Implementations

impl<T> Ranged for GroupBy<T> where
    T::ValueType: PrimInt + ToPrimitive + FromPrimitive + Mul,
    T: Ranged, 

type ValueType = T::ValueType

The type of this value

fn map(&self, value: &T::ValueType, limit: (i32, i32)) -> i32

This function maps the value to i32, which is the drawing coordinate

fn range(&self) -> Range<T::ValueType>

Get the range of this value

fn key_points(&self, max_points: usize) -> Vec<T::ValueType>

This function gives the key points that we can draw a grid based on this

fn axis_pixel_range(&self, limit: (i32, i32)) -> Range<i32>

This function provides the on-axis part of its range

impl<T> DiscreteRanged for GroupBy<T> where
    T::ValueType: PrimInt + ToPrimitive + FromPrimitive + Mul,
    T: Ranged + DiscreteRanged, 

type RangeParameter = <T as DiscreteRanged>::RangeParameter

fn get_range_parameter(&self) -> Self::RangeParameter

fn previous_value(
    this: &Self::ValueType,
    param: &Self::RangeParameter
) -> Self::ValueType

Get the largest value that is smaller than this value

fn next_value(
    this: &Self::ValueType,
    param: &Self::RangeParameter
) -> Self::ValueType

Get the smallest value that is larger than the this value

impl<T> AsRangedCoord for GroupBy<T> where
    T::ValueType: PrimInt + ToPrimitive + FromPrimitive + Mul,
    T: Ranged, 

type Value = T::ValueType

type CoordDescType = Self
