我试图在x轴上生成月,年的图表。请在下面查看以下内容:
图表的数据是通过ajax获得的。请查看以下样本json:
{"total":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,475],[2013,11,0],[2013,12,0],[2014,1,367],[2014,2,0],[2014,3,0]],"critical":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,0],[2013,11,0],[2013,12,0],[2014,1,1],[2014,2,0],[2014,3,0]],"high":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,20],[2013,11,0],[2013,12,0],[2014,1,20],[2014,2,0],[2014,3,0]],"medium":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,24],[2013,11,0],[2013,12,0],[2014,1,135],[2014,2,0],[2014,3,0]],"low":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,42],[2013,11,0],[2013,12,0],[2014,1,26],[2014,2,0],[2014,3,0]]}
在上面的例子中[2013,4,0]应转换为x轴:2013年4月,y轴:0。
请告诉我如何实现这一目标?
感谢。

我是这样做的:
// your JSON
obj = {"total":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,475],[2013,11,0],[2013,12,0],[2014,1,367],[2014,2,0],[2014,3,0]],"critical":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,0],[2013,11,0],[2013,12,0],[2014,1,1],[2014,2,0],[2014,3,0]],"high":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,20],[2013,11,0],[2013,12,0],[2014,1,20],[2014,2,0],[2014,3,0]],"medium":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,24],[2013,11,0],[2013,12,0],[2014,1,135],[2014,2,0],[2014,3,0]],"low":[[2013,4,0],[2013,5,0],[2013,6,0],[2013,7,0],[2013,8,0],[2013,9,0],[2013,10,42],[2013,11,0],[2013,12,0],[2014,1,26],[2014,2,0],[2014,3,0]]};
// reformat into the format flot likes
seriesData = [];
for (var prop in obj) {
// push in the series, the "property" is the label
// use $.map to produce an array of [date, y-value]
// the new Date(i[0],i[1]-1).getTime(),
// will give you the epoch time for the first day of that month/year
seriesData.push({label: prop, data:$.map(obj[prop], function(i,j){
return [[new Date(i[0],i[1]-1).getTime(), i[2]]];
})});
}
// plot it!
$.plot("#placeholder", seriesData, {
xaxis: { mode: "time", timeformat: "%b %Y" }
});
小提琴here。
修改:j
已i[2]
更改,以显示正确绘制的数据。

在选项中:
xaxis: {mode: "time", timeformat: "%b %m"}
使用time plugin。
必须将数据转换为时间戳,如链接中所述。因为你当天有0,可能是这样的:
tstamp = new Date(dat[0]*1000*3600*24*30*12+dat[1]*1000*3600*24*30)
