The chartRegistry object maintains sets of all instantiated dc.js charts under named groups and the default group. See ChartRegistry for its methods.
General configuration object; see Config for members.
d3.js compatiblity layer
Clear given group if one is provided, otherwise clears all groups.
Parameters: Name Type Descriptiongroup String
Group name
Remove given chart instance from the given group, creating the group if necessary. If no group is provided, the default group constants.DEFAULT_CHART_GROUP will be used.
chart Object
dc.js chart instance
group String <optional>
Group name
Clear all filters on all charts within the given chart group. If the chart group is not given then only charts that belong to the default chart group will be reset.
Parameters: Name Type Argument Descriptiongroup String <optional>
Determine if a given chart instance resides in any group in the registry.
Parameters: Name Type Descriptionchart Object
dc.js chart instance
Returns a function that given a string property name, can be used to pluck the property off an object. A function can be passed as the second argument to also alter the data being returned.
This can be a useful shorthand method to create accessor functions.
Parameters: Name Type Argument Descriptionn String f function <optional>
var xPluck = pluck('x');
var objA = {x: 1};
xPluck(objA) // 1
var xPosition = pluck('x', function (x, i) {
// `this` is the original datum,
// `x` is the x property of the datum,
// `i` is the position in the array
return this.radius + x;
});
selectAll('.circle').data(...).x(xPosition);
Redraw all charts belong to the given chart group. If the chart group is not given then only charts that belong to the default chart group will be re-drawn. Redraw is different from re-render since when redrawing dc tries to update the graphic incrementally, using transitions, instead of starting from scratch.
Parameters: Name Type Argument Descriptiongroup String <optional>
Reset zoom level / focus on all charts that belong to the given chart group. If the chart group is not given then only charts that belong to the default chart group will be reset.
Parameters: Name Type Argument Descriptiongroup String <optional>
Add given chart instance to the given group, creating the group if necessary. If no group is provided, the default group constants.DEFAULT_CHART_GROUP will be used.
chart Object
dc.js chart instance
group String <optional>
Group name
Re-render all charts belong to the given chart group. If the chart group is not given then only charts that belong to the default chart group will be re-rendered.
Parameters: Name Type Argument Descriptiongroup String <optional>
Start a transition on a selection if transitions are globally enabled (disableTransitions is false) and the duration is greater than zero; otherwise return the selection. Since most operations are the same on a d3 selection and a d3 transition, this allows a common code path for both cases.
Parameters: Name Type Argument Default Descriptionselection d3.selection
the selection to be transitioned
duration Number | function <optional>
the duration of the transition in milliseconds, a function returning the duration, or 0 for no transition
delay Number | function <optional>
the delay of the transition in milliseconds, or a function returning the delay, or 0 for no delay
name String <optional>
the name of the transition (if concurrent transitions on the same elements are needed)
