Tutorials

[Introduction Introduction]: how SVGFig basically works
[PlottingTutorial Plotting Tutorial]: tutorial for plotting mathematical functions
[ExampleGallery Example Gallery]: shows what SVG can do

[http://code.google.com/p/svgfig/w/list?q=label:Reference Click here] for an alphabetized list of all SVGFig reference pages. (Note that you can search their contents.)

[ClassSVG SVG]: class representing an SVG image
[DefCanvas canvas and canvas_outline]: functions for explicitly laying out the SVG canvas; good for changing the aspect ratio
[Defload load and load_stream]: functions for loading SVG files from files or XML streams
[DefTemplate template]: loads an SVG template, replacing all instances of "<REPLACEME />" with an SVG object

SVG graphics helpers
[DefRgb rgb]: expresses an rgb triple as a hex string
[DefMake_symbol make_symbol]: makes a <symbol /> element from a template of standard shapes
[DefMake_marker make_marker]: makes a <marker /> element from a template

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

for making transformation functions
[DefTotrans totrans]: turns a string expression or complex function into an R^2^-to-R^2^ function
[DefWindow window]: creates a transformation by mapping a rectangle of "inner" coordinates to a rectangle of "outer" coordinates
[DefRotate rotate]: creates a simple rotation of the plane

[ClassPath Path]: a transformable representation of an SVG path
[DefPathtoPath pathtoPath]: converts SVG <path /> objects into transformable Paths
[ClassCurve Curve]: draws a parametric function; implements the adaptive sampling algorithm
[DefFuncRtoR2 funcRtoR2]: turns a string expression into a parametric function suitable for drawing with Curve
[DefFuncRtoC funcRtoC]: turns a complex string expression into a parametric function
[DefFuncRtoR funcRtoR]: turns a one-dimensional function into a parametric function
[ClassPoly Poly]: draws a line through a sequence of points; may be piecewise linear, Bézier, a velocity curve, or smooth
[ClassDots Dots]: draws SVG symbols at a set of points
[ClassYErrorBars YErrorBars and XErrorBars]: draw error bars (usually used with Dots), including multiple bars (e.g. for correlated and uncorrelated errors)

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

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