An area series is similar to a line series but use a filled polygon
The backend that drawing a bitmap
The element that contains a bitmap on it
The boxplot element
The candlestick data point element
A 2D Cartesian coordinate system described by two 1D ranged coordinate specs.
The helper object to create a chart context, which is used for the high-level figure drawing. With the help of this object, we can convert a basic drawing area into a chart context, which allows the high-level charting API being used on the drawing area.
The context of the chart. This is the core object of Plotters. Any plot/chart is abstracted as this type, and any data series can be placed to the chart context.
A circle element
Describe a cross
The abstraction of a drawing area. Plotters uses drawing area as the fundamental abstraction for the high level drawing API. The major functionality provided by the drawing area is 1. Layout specification - Split the parent drawing area into sub-drawing-areas 2. Coordinate Translation - Allows guest coordinate system attached and used for drawing. 3. Element based drawing - drawing area provides the environment the element can be drawn onto it.
This is the dummy backend placeholder for the backend that never fails
The container for a dynamically dispatched element
An empty composable element, which is the start point of an ad-hoc composable element
Describes a font
Grouping the value in the coordinate specification.
The color described by HSL color space
The series that aggregate data into a histogram
The line series object, which takes an iterator of points in guest coordinate system and creates the element rendering the line plot
The coordinate combinator that transform a continous coordinate to a discrete coordinate to a discrete coordinate by a giving step.
A log scaled coordinate axis
The logarithmic coodinate decorator. This decorator is used to make the axis rendered as logarithmically.
An multi-line text element. The Text element allows only single line text
and the MultiLineText supports drawing multiple lines
A nested coordinate spec which is a discrete coordinate on the top level and for each value in discrete value, there is a secondary coordinate system. And the value is defined as a tuple of primary coordinate value and secondary coordinate value
The palette of 99% accessibility
The palette of 100% accessibility
The palette of 99.99% accessibility
A color in the given palette
An element of a series of connected lines
An element of a single pixel
The point plot object, which takes an iterator of points in guest coordinate system and create an element for each point
An element of a filled polygon
The quartiles
The color described by its RGB value
The ranged coordinate for date
The ranged coordinate for the date and time
The coordinate that for duration of time
The representation of the rectangle in backend canvas
A rectangle element
The SVG image drawing backend
Style for any of shape
The surface series.
A single line text element. This can be owned or borrowed string, dependents on
String or str moved into.
Style of a text
Describe a triangle marker
Enums
The error description of any drawing area API
Describes font family. This can be either a specific font family name, such as “arial”, or a general font family class, such as “serif” and “sans-serif”
Describes the font style. Such as Italic, Oblique, etc.
Specifying text transformations
The enum used to specify the position of label area. This is used when we configure the label area size with the API ChartBuilder::set_label_area_size(struct ChartBuilder.html#method.set_label_area_size)
Describe a value for a nested coordinate
The value that used by the segmented coordinate.
Describes where we want to put the series label
Constants
The predefined black color
The predefined blue color
The predefined cyan color
The predefined green color
The predefined magenta color
The predefined red color
The predefined transparent
The predefined white color
The predefined yellow color
Traits
Allows a value turns into a relative size
Any color representation
The trait that translates some customized object to the backend coordinate
The trait indicates the coordinate is discrete This means we can bidirectionally map the range value to 0 to N in which N is the number of distinct values of the range.
The drawing backend trait, which implements the low-level drawing APIs.
This trait has a set of default implementation. And the minimal requirement of
implementing a drawing backend is implementing the draw_pixel function.
A type which can be converted into a root drawing area
The trait that makes the conversion from the statically dispatched element to the dynamically dispatched element
The trait that allows some type turns into a font description
Convert a range to a log scale coordinate spec
The trait that converts a normal date coord into a yearly one
The trait for the types that can be converted into a partial axis
The trait for types that can decorated by SegmentedCoord decorator.
The trait that converts a normal date coord into a yearly one
The trait for the type that is able to be presented in the log scale. This trait is primarily used by LogRangeExt.
The trait that indicates we have a ordered and ranged value Which is used to describe any 1D axis.
The trait that provides method Self::group_by function which creates a
GroupBy decorated ranged value.
Functions
Generates a frequency response plot for a given audio processor
Make a partial axis based on the percentage of visible portion.
We can use into_partial_axis to create a partial axis range specification.
But sometimes, we want to directly specify the percentage visible to the user.
Type Definitions
The type used to returns a drawing operation that can be failed
