Reference Table of Contents

Fundamentals

• SVG: class representing an SVG image
• canvas and canvas_outline: functions for explicitly laying out the SVG canvas; good for changing the aspect ratio
• load and load_stream: functions for loading SVG files from files or XML streams
• template: loads an SVG template, replacing all instances of "

  <replaceme>

  </replaceme>

  " with an SVG object

• SVG graphics helpers
• rgb: expresses an rgb triple as a hex string
• make_symbol: makes a

  <symbol>

  </symbol>

  element from a template of standard shapes
• make_marker: makes a

  <marker>

  </marker>

  element from a template

• Fig: holds a set of transformable primitives and globally-positioned SVG objects, composes transformations when nested
• Plot: a Fig with coordinate axes
• Frame: a Fig in a coordinate frame

• for making transformation functions
• totrans: turns a string expression or complex function into an R²-to-R² function
• window: creates a transformation by mapping a rectangle of "inner" coordinates to a rectangle of "outer" coordinates
• rotate: creates a simple rotation of the plane

Fig Primitives

• General features of all primitives

• Path: a transformable representation of an SVG path
• pathtoPath: converts SVG

  <path>

  </path>

  objects into transformable Paths
• Curve: draws a parametric function; implements the adaptive sampling algorithm
• funcRtoR2: turns a string expression into a parametric function suitable for drawing with Curve
• funcRtoC: turns a complex string expression into a parametric function
• funcRtoR: turns a one-dimensional function into a parametric function
• Poly: draws a line through a sequence of points; may be piecewise linear, Bézier, a velocity curve, or smooth
• Dots: draws SVG symbols at a set of points
• YErrorBars and XErrorBars: draw error bars (usually used with Dots), including multiple bars (e.g. for correlated and uncorrelated errors)

• Line: draws a line between two points; if the coordinate transformation is non-linear, the line may be curved
• LineGlobal: draws a straight line between two points, one or both of which are in global coordinates
• VLine and HLine: draws vertical and horizontal lines (provided as a convenience)
• Rect: draws a rectangle joining four points
• Ellipse: draws an ellipse with semimajor axis and a semiminor length (does not need to be aligned with the X-Y axis)
• Grid, HGrid, and VGrid: draws a set of horizontal and vertical lines

• Text: places text at a local coordinate
• TextGlobal: places text at a global coordinate

Coordinate Axes

• Standard tick specification methods

• Axes: draws an orthogonal coordinate axis in the local coordinate system
• Ticks: superclass of everything with tick marks; implements the tick-guessing algorithm
• CurveAxis: draws ticks along a parametric function
• LineAxis: draws ticks along a line; useful for measuring the distance between points
