想截取最新的十行里第一列和第二列的数据制作数据在chartjs里做图表，请问各位大大怎么操作呢？

直接用js就行了，labels是横坐标数组，datas是具体的数据
var rawData = `2017.06.15_12:24:55 3046 9
2017.06.15_12:25:25 3017 9
2017.06.15_12:25:55 3003 9
2017.06.15_12:26:26 3039 9
2017.06.15_12:26:56 3078 9
2017.06.15_12:27:26 3343 10
2017.06.15_12:27:56 3272 10
2017.06.15_12:28:26 3260 10
2017.06.15_12:28:57 3406 10
2017.06.15_12:29:27 3744 11
2017.06.15_12:29:57 4031 12
2017.06.15_12:30:27 4201 13
2017.06.15_12:30:57 4222 13
2017.06.15_12:31:28 4036 12
2017.06.15_12:31:58 3893 12
2017.06.15_12:32:28 3823 11
2017.06.15_12:32:58 3806 11
2017.06.15_12:33:28 4843 14
2017.06.15_12:33:59 4782 14
2017.06.15_12:34:29 4517 13`;

var labels = [];
var datas = [];
rawData.split("\n").forEach(function(value, key) {

    var arr = value.split(' ');
    labels.push(arr[0]);
    datas.push(arr[1]);
    if (key > 10) {
            return;
    }

});

var rawData = <?php echo file_get_contents('路径/xxx.txt');?>;

十条的问题我写错了，forEach那段代码改成这样就是十条了
rawData.split("\n").forEach(function(value, key) {

if (key >= 10) {
  return;
}
var arr = value.split(' ');
labels.push(arr[0]);
datas.push(arr[1]);

});
