xAxis: {
categories: eval(“[” + $.ajax({url:”{:U(‘user/dtu/getdata2’)}”,async:false}).responseText + “]”) //获取数据源操作信息
// [‘0:00’, ‘0:30’, ‘1:00’, ‘1:30’]
// $.ajax({url:”{:U(‘user/dtu/getdata’)}”,async:false}).responseText
},
yAxis: {
title: {
text: ‘ph值’

}
},
plotOptions: {
spline: {
lineWidth: 4,
states: {
hover: {
lineWidth: 5
}
},
marker: {
enabled: false
//radius: 10
},
// pointInterval: 3600000, // one hour
// pointStart: Date.UTC(2009, 9, 6, 0, 0, 0)
