我有这种格式的json：
[
{
"2007": [
{
"date": "2014-1-11",
"val": "4"
},
{
"date": "2014-1-11",
"val": "5"
}
],
"2008": {
"date": "2014-1-11",
"val": "6"
}
}
]
尝试使用highcharts显示数据，其中每年（json节点）是一个系列的名称，年节点的子节点是一个行字符，其中y轴为val，x轴为日期：

jsonString应采用什么格式才能正确显示？

你的JSON应该包含x / y参数的对象数组（点），而不是自定义。日期应为时间戳（以毫秒为单位的时间），但值为数字。
[{"x": 1389398400000,"y": 4},{"x": 1389398400000,"y": 5},{"x": 1389398400000,"y": 6}]
