Module combinators

The coordinate combinators

Coordinate combinators are very important part of Plotters’ coordinate system. The combinator is more about the “combinator pattern”, which takes one or more coordinate specification and transform them into a new coordinate specification.

Structs

• GroupBy
  Grouping the value in the coordinate specification.
• Linspace
  The coordinate combinator that transform a continuous coordinate to a discrete coordinate to a discrete coordinate by a giving step.
• LogCoord
  A log scaled coordinate axis
• LogRangeDeprecated
  The logarithmic coordinate decorator. This decorator is used to make the axis rendered as logarithmically.
• NestedRange
  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
• WithKeyPointMethod
  The coordinate decorator that allows customized keypoint algorithms. Normally, all the coordinate spec implements its own key point algorithm But this decorator allows you override the pre-defined key point algorithm.
• WithKeyPoints
  The coordinate decorator that binds a key point vector. Normally, all the ranged coordinate implements its own keypoint algorithm to determine how to render the tick mark and mesh grid. This decorator allows customized tick mark specifiied by vector. See BindKeyPoints::with_key_points for details. Note: For any coordinate spec wrapped by this decorator, the maximum number of labels configured by MeshStyle will be ignored and the key point function will always returns the entire vector

Enums

• NestedValue
  Describe a value for a nested coordinate

Traits

• BindKeyPointMethod
  Bind an existing coordinate spec with a given key points algorithm. See WithKeyPointMethod for more details.
• BindKeyPoints
  Bind a existing coordinate spec with a given key points vector. See WithKeyPoints for more details.
• BuildNestedCoord
  Used to build a nested coordinate system.
• IntoLinspace
  Makes a linspace coordinate from the ranged coordinates.
• IntoLogRange
  Convert a range to a log scale coordinate spec
• IntoPartialAxis
  The trait for the types that can be converted into a partial axis
• LogScalable
  The trait for the type that is able to be presented in the log scale. This trait is primarily used by LogRangeExt.
• ToGroupByRange
  The trait that provides method Self::group_by function which creates a GroupBy decorated ranged value.

Functions

• make_partial_axis
  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.
