2D Affine Transformation Matrix in row major order

A rectangle for bounding boxes

Line cap style

A Layout which puts elements into columns.

A Renderable element for data sources

Unlike most other Renderable's DataElem is a placeholder in the scene graph. nspl does not insert the individual data rows into the scene graph but represent them with a DataElem. The data source will be enumerated at the time when the rendering context renders the DataElem.

A DataRenderer can render a datum a a side effect

DataRenderers describe the visual representations of single data rows. DataRenderers operate in a side effect with the provided context specific shape and textbox renderer.

It is guaranteed that the render method is called in a loop on all rows of a data source, after which the clear method is called exactly once.

Data renderers interpret the data rows as it is applicable for their function e.g. the point renderer takes 2 numbers for the x, y coordinates and potentially numbers for the color value, and the top and bottom error bars. In contrast the box and whiskes renderer takes 5 numbers for the min/max/median/mean and the horizontal coordinate. If the data row is too short for the given data renderer then an error is thrown.

A Renderable of an Either of Renderables

A Renderable of a sequence of Renderables

A Renderable of a sequence of Eithers of Renderables

A Renderable of a sequence of Options of Renderables

Describes the name and size of the font set used to draw letters

This description is independent of the rendering context. Each rendering context has to provide a GlyphMeasurer to compute the concrete space occupied by the given Font (font name and font size)

A Font paired with a GlyphMeasurer forms a FontConfiguration

A Layout which does nothing.

A Layout which stacks elements beside each other and aligns the vertical axis.

Semantic information about parts of a plot

Layouts tranform the bounding box of their members.

Describes a line segment with the two end points

Class which holds common settings of plots.

This class is immmutable.

The intended use of this class is to call the specialized copy methods on the default instance in org.nspl.par e.g.

org.nspl.par.withXLog(true).withMain("some text")

or equivalently

org.nspl.par.xlog(true).main("some text")

For each member of this class there are two copy methods:

• One following the naming convention withX.. e.g. def withXLog(v:Boolean) : Parameters
• the other omitting the with prefix, e.g. def xlog(v:Boolean) : Parameters

A shape built up by a path

A path is a sequence of of path operations:

• move to point
• line to point (from last point)
• quadratic to (from last point)
• cubic to (from last point)

Final rendered bounds (if available) and identifier of a plot area

A raw reference used for reference based equality tests

Used to identify certain parts of a composit plot

2D point

Relative font size

A relative font size of 1 represents the horizontal space taken by one letter

Basic unit of the scene graph.

A Renderer provides a way to render a type into a RenderingContext

Concrete RenderingContext implementations need a Shape and TextBox renderer.

Abstract rendering context

Provides methods to manipulate a state machine of transformation states

Description of a 2D shape

A Renderable describing a shape

Path without curves. Points are joined by line segments.

Font independent Stroke

Width and dash are expressed in terms of doubles

Font dependent Stroke

Width and dash are expressed in terms of a relative font size

A Layout which puts elements into rows.

A Renderable describing a text box

See the apply factory method in its companion object on how to construct one

Holds a text layout

A Layout which stacks elements on top of each other and aligns the horizontal axis.

A drag event over a plot area.
