new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

For series: dispatchAction({type: 'highlight', seriesIndex?: number | number[], seriesId?: string | string[], seriesName?: string | string[], dataIndex?: number | number[], name?: string | string[]}). For geo component (since v5.1.0): dispatchAction({type: 'highlight', geoIndex?: number | number[], geoId?: string | string[], geoName?: string | string[], name?: string | string[]}).

The downplay action downplays specified data graphics. For series: dispatchAction({type: 'downplay', seriesIndex?: number | number[], seriesId?: string | string[], seriesName?: string | string[], dataIndex?: number | number[], name?: string | string[]}). For geo component (since v5.1.0): dispatchAction({type: 'downplay', geoIndex?: number | number[], geoId?: string | string[], geoName?: string | string[], name?: string | string[]}).

select action - series data

The select action selects specified data. Selected data will apply the style of series-bar.select. dispatchAction({type: 'select', seriesIndex?: number | number[], seriesId?: string | string[], seriesName?: string | string[], dataIndex?: number | number[], name?: string | string[]}).

unselect action - series data

The unselect action unselects specified data. dispatchAction({type: 'unselect', seriesIndex?: number | number[], seriesId?: string | string[], seriesName?: string | string[], dataIndex?: number | number[], name?: string | string[]}).

dispatchAction usage pattern

Chart actions in ECharts are triggered through the dispatchAction method on the chart instance. All action parameters marked with ?: are optional.

dispatchAction for triggering component actions

Actions can be triggered programmatically through myChart.dispatchAction({ type: '' }) method. This unified approach manages all actions and may record user event paths. This replaces the ECharts 2.x approach of myChart.component.tooltip.showTip.
