axis(context) Render the axis to the given context, which may be either a selection of SVG containers (either SVG or G elements) or a corresponding transition.

armadillo.parallel([parallel]) Defaults to 20°.

area.y1([y]) If y is specified, sets the y1 accessor to the specified function or number and returns this area generator. If y is not specified, returns the current y1 accessor, which defaults to: function y(d) { return d[1]; } A null accessor is also allowed, indicating that the previously-computed y0 value should be reused for the y1 value. When an area is generated, the y1 accessor will be invoked for each defined element in the input data array, being passed the element d, the index i,

area.y0([y]) If y is specified, sets the y0 accessor to the specified function or number and returns this area generator. If y is not specified, returns the current y0 accessor, which defaults to: function y() { return 0; } When an area is generated, the y0 accessor will be invoked for each defined element in the input data array, being passed the element d, the index i, and the array data as three arguments. See area.x0 for more information.

area.y([y]) If y is specified, sets y0 to y and y1 to null and returns this area generator. If y is not specified, returns the current y0 accessor.

area.x1([x]) If x is specified, sets the x1 accessor to the specified function or number and returns this area generator. If x is not specified, returns the current x1 accessor, which defaults to null, indicating that the previously-computed x0 value should be reused for the x1 value. When an area is generated, the x1 accessor will be invoked for each defined element in the input data array, being passed the element d, the index i, and the array data as three arguments. See area.x0 for more

area.x0([x]) If x is specified, sets the x0 accessor to the specified function or number and returns this area generator. If x is not specified, returns the current x0 accessor, which defaults to: function x(d) { return d[0]; } When an area is generated, the x0 accessor will be invoked for each defined element in the input data array, being passed the element d, the index i, and the array data as three arguments. The default x0 accessor assumes that the input data are two-element arrays of

area.x([x]) If x is specified, sets x0 to x and x1 to null and returns this area generator. If x is not specified, returns the current x0 accessor.

area.lineY1() Returns a new line generator that has this area generator’s current defined accessor, curve and context. The line’s x-accessor is this area’s x0-accessor, and the line’s y-accessor is this area’s y1-accessor.

area.lineX1() Returns a new line generator that has this area generator’s current defined accessor, curve and context. The line’s x-accessor is this area’s x1-accessor, and the line’s y-accessor is this area’s y0-accessor.
