HighCharts堆叠图表xAxis与json不工作

Question

这是我从json中获得的字符串

var str = "6,21,22,23,24,25,26,27,28";
xAxis: {
categories: []   // want to update this part (HighCharts)
},

我无法用

更新xAxis

Highcharts.charts[0].xAxis[0].update({categories:[str]}, true);

请帮助是否有语法问题??

Answer 1

您需要将字符串转换为字符串数组，例如:

chart.xAxis[0].setCategories(str.split(','));
