如何制作具有多列数据的多折线图？
数据示例：

var data75 = [{"d":1,'a1':50,'a2':70},
{"d":2,'a1':90,'a2':71},
{"d":3,'a1':40,'a2':90},
{"d":4,'a1':15,'a2':70},
{"d":5,'a1':150,'a2':60},
{"d":6,'a1':53,'a2':20},
{"d":7,'a1':59,'a2':40},
{"d":8,'a1':30,'a2':50},
{"d":9,'a1':70,'a2':77},
{"d":10,'a1':52,'a2':72},
{"d":11,'a1':56,'a2':10},
{"d":12,'a1':57,'a2':40},];

d = x 轴；
a1 和 a2 = 2 个不同系列中的 y 轴；
