Class: seriesChart

dc. seriesChart

new seriesChart(parent [, chartGroup])

A series chart is a chart that shows multiple series of data overlaid on one chart, where the series is specified in the data. It is a specialization of Composite Chart and inherits all composite features other than recomposing the chart.

Examples:

Parameters:
Name Type Argument Description
parent String | node | d3.selection

Any valid d3 single selector specifying a dom block element such as a div; or a dom element or d3 selection.
chartGroup String <optional>

The name of the chart group this chart instance should be placed in. Interaction with a chart will only trigger events and redraws within the chart's group.

// do a scatter series chart
chart.chart(dc.scatterPlot)

Returns:
Type
function | dc.seriesChart

// Default value sort
_chart.valueSort(function keySort (a, b) {
    return d3.ascending(_chart.keyAccessor()(a), _chart.keyAccessor()(b));
});
