highcharts 线性图表

//引入highcharts.js

<script type="text/javascript">
$(function(){

rotation : 67  //这个是控制x坐标轴 x值的字体方向

//题外话：突然想起来前几天朋友说腾讯的一个面试题，写一个二维数组的json格式？？你能写出来么？？====》要看这个二维数组是关联还是索引数组哦~~  四种！！

echo json_encode(array(array(1,2,3),array(4,5,6))).'<br/>';
echo json_encode(array(array(1=>'1',2=>'b',3=>'c'),array(4=>'d',5=>'e',6=>'f'))).'<br/>';
echo json_encode(array('a'=>array(1,2,3),'b'=>array(4,5,6))).'<br/>';
echo json_encode(array('a'=>array(1=>'1',2=>'b',3=>'c'),array(4=>'d',5=>'e',6=>'f'))).'<br/>';

答案：
[[1,2,3],[4,5,6]]
[{"1":"1","2":"b","3":"c"},{"4":"d","5":"e","6":"f"}]
{"a":[1,2,3],"b":[4,5,6]}
{"a":{"1":"1","2":"b","3":"c"},"0":{"4":"d","5":"e","6":"f"}}

===》由此可见：索引用方括号[]   关联用大括号{}=====》引申  来！写一个三维的   array('a'=>array(1,2,3),array('b'=>array(1,2,3)));

{"a":[1,2,3],"0":{"b":[1,2,3]}}
