d3
Thin wrapper over the data-driven documents (d3) library for use with gopherjs.
This is just enough of the d3 library to allow you to complete the Mark Bostock's excellent tutorial, but writing entirely in go.
The calls are not very regularized because they haven't been thought through with respect to statically-typed programming model.
Install
go get -u github.com/iansmith/d3
Check out the demo.

Functions ¶
func Max ¶
func Max(v js.Object, fn ExtractorFunc) int64
Max is d3.max with a function that passes over each object in the array supplied as the first argument. If the second function is nil, we assume that the array contains (JS) integers.
Types ¶
type Axis ¶
type Axis interface {
ScaleO(OrdinalScale) Axis
Scale(LinearScale) Axis
Orient(e Edge) Axis
Ticks(int64, string) Axis
}
Axis is a VERY thin wrapper over d3.svg.axis
type ExtractorFunc ¶
ExtractorFunc is a fun that can pull the int value from an object
type ExtractorFuncF ¶
ExtractorFuncF is a fun that can pull the float value from an object
type ExtractorFuncO ¶
ExtractorFuncO is a fun that can pull the named (usually ordinal) value from the object
type FilterFunc ¶
FilterFunc converts "raw" objects to their formatted counterparts. Raw version has only string fields, but formatted version should have the parsed values. If this func returns nil, that item is ignored.
type LinearScale ¶
type LinearScale interface {
Domain([]int64) LinearScale
DomainF([]float64) LinearScale
Range([]int64) LinearScale
Linear(js.Object, ExtractorFunc) int64
LinearF(js.Object, ExtractorFuncF) float64
Invert(js.Object, ExtractorFunc) int64
Func(ExtractorFunc) func(js.Object) int64
FuncF(ExtractorFuncF) func(js.Object) float64
}
LinearScale is a wrapper around the d3 concept of the same name.
func ScaleLinear ¶
func ScaleLinear() LinearScale
ScaleLinear is d3.scale.linear and returns a LinearScale
type OrdinalScale ¶
type OrdinalScale interface {
Domain(js.Object) OrdinalScale
RangeBands([]int64) OrdinalScale
RangeBand() int64
RangeBandF() float64
RangeBands3([]int64, float64) OrdinalScale
Ordinal(obj js.Object, fn ExtractorFuncO) int64
}
OrdinalScale wraps d3.scale.ordinal
func ScaleOrdinal ¶
func ScaleOrdinal() OrdinalScale
ScaleLinear is d3.scale.ordinal and returns a Ordinal
type PropertyName ¶
type PropertyName string
PropertyName is the name of a CSS property like "width"
type Selection ¶
type Selection interface {
Append(TagName) Selection
SelectAll(Selector) Selection
Data(js.Object) Selection
Enter() Selection
Style(PropertyName, func(js.Object) string) Selection
StyleS(PropertyName, string) Selection
Text(func(js.Object) string) Selection
TextS(string) Selection
Attr(PropertyName, int64) Selection
AttrF(PropertyName, float64) Selection
AttrS(PropertyName, string) Selection
AttrFunc(PropertyName, func(js.Object) int64) Selection
AttrFuncF(PropertyName, func(js.Object) float64) Selection
AttrFunc2S(PropertyName, func(js.Object, int64) string) Selection
AttrFuncS(PropertyName, func(js.Object) string) Selection
Call(Axis) Selection
}
Selection is the d3 concept of zero or more selected elements.
