When drilling down highcharts, you will encounter problems if you want to display multiple series, such as the following data series returned by the drill:
var series = [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
If you return an array, you can't directly add SeriesAsDrilldown(point, series), and you won't be able to display anything directly. Only the first addSeriesAsDrilldown(point,series[0]) can be obtained.
In order to display a series normally, we want to show all the content in the series. So what should we do if we change it? It's actually very simple:
Remove the addSeriesAsDrilldown(point, series) sentence directly and replace it with the following method:
for(var i = 0; i < series.length; i ++){
chart.addSingleSeriesAsDrilldown(e.point, series[i]);
}
chart.applyDrilldown();
What does it mean? In fact, you can open drilldown.src.js see the corresponding addSeriesAsDrilldown and addSingleSeriesAsDrilldown methods, and I won't explain it in detail here
Drilling down can realize the display of multiple series, how about it, it's simple.
