======================================================
{
"datastreams":[
{

"id":"temp",
"datapoints":[
{
"value":25
}
]
}
]
}


{"datastreams":[{"id":"temp","datapoints":[{"value":25}]}]}
type1以折线图方式展示，type3用的json方式展示

=======================================================
{
"datastreams":[
{

"id":"temp",
"datapoints":[
{
"value":25
}
]
},

{

"id":"temp2",
"datapoints":[
{
"value":25
}
]
}

]
}
传多个数据点
=======================================================
增加时间戳
{
"datastreams":[
{

"id":"temp",
"datapoints":[
{
"at":"2013-04-22 22:22:22",
"value":25
}
]
}
]
}
=======================================================
{
"datastreams":[
{

"id":"temp",
"datapoints":[
{
"at":"2013-04-22 22:22:22",
"value":"25"
}
]
}
]
}
=======================================================

{
"datastreams":[
{

"id":"temp",
"datapoints":[
{
"at":"2013-04-22 22:22:22",
"value":"25:ffdfdf"
}
]
}
]
}
=======================================================
{"datastreams":[{"id":"location","datapoints":[{"value":{"lon":106,"lat":29}}]}]}
显示地图，type1显示地图，type3显示json
{"GPS":{"lat":29.62514,"lon":106.48901}}

=======================================================
{
"datastreams":[
{

"id":"temp",
"datapoints":[
{
"value":25
}
]
}
]

,
"datastreams2":[
{

"id":"temp",
"datapoints":[
{
"value":25
}
]
}
]
}

以上为多个数据流
