如何更改字幕而不是标题?
series: {
cursor: 'pointer',
point: {
events: {
click: function() {//alert ('Category: '+ this.category +', value: '+ this.y);
var drilldown = this.drilldown;
if (drilldown) { // drill down
this.series.chart.setTitle({
text: drilldown.name
});
} else { // restore
}
}
}
}
}
},
会是这样的吗:
this.series.chart.setSubTitle({
text: 'vlabla'
});
我尝试了上面的它不起作用
请帮助任何人?
最佳答案
图表中有drilldown和drillup事件可用于调用chart.setTitle()
。要仅设置字幕并保持标题不变,可以将标题选项对象设置为null:
chart.setTitle(null, {
text: "after drilldown subtitle" //subtitle options
});
