Steps to Reproduce

let base = +new Date(1988, 9, 3); let oneDay = 24 * 3600 * 1000; let data = [[base, Math.random() * 300]]; for (let i = 1; i < 20000; i++) { let now = new Date((base += oneDay)); data.push([+now, Math.round((Math.random() - 0.5) * 20 + data[i - 1][1])]); } option = { tooltip: { trigger: 'axis', position: function (pt) { return [pt[0], '10%']; } }, title: { left: 'center', text: 'Large Ara Chart' }, toolbox: { feature: { dataZoom: { yAxisIndex: 'none' }, restore: {}, saveAsImage: {} } }, xAxis: { type: 'time', boundaryGap: false }, yAxis: { type: 'value', boundaryGap: [0, '100%'] }, dataZoom: [ { type: 'inside', start: 0, end: 20 }, { start: 0, end: 20 } ], series: [ { name: 'Fake Data', type: 'line', smooth: true, symbol: 'none', areaStyle: {}, data: data } ] }; myChart.dispatchAction({ type: 'takeGlobalCursor', key: 'dataZoomSelect', // 启动或关闭 dataZoomSelectActive: true });

Current Behavior

myChart.dispatchAction({ type: 'takeGlobalCursor', key: 'dataZoomSelect', // 启动或关闭 dataZoomSelectActive: true });

Hi @pissang @Ovilia

As above, dispatching this action:

myChart.dispatchAction({
    type: 'takeGlobalCursor',
    key: 'dataZoomSelect',
    dataZoomSelectActive: true // activate or inactivate
})

Does not activate the zoom select feature of the chart. However, using the toolbox button does work. It is expected that this should work via actions, from the documentation: https://echarts.apache.org/en/api.html#action.dataZoom.takeGlobalCursor

This means that it is broken for anyone using a customised toolbox which triggers the zoom selection via actions. This is broken in each version of ECharts, at least from 5.2.2 onwards (more than 1 year), maybe further back.

Are you able to help with this?

Many thanks!
