怎么把 $mydata->addpoints(array(150,220,300,250,420,200,300,200,100),test);的字符串test显示为中文，怎么把 $mydata->setaxisname(0,hits);显示中文，比如 $mydata->setaxisname(0,套);。。
------解决方案--------------------
直接中文写上去不行吗？
------解决方案--------------------
注释掉 header(content-type:text/html; charset=utf-8);
------解决方案--------------------
是最新版的吗？
待会下一个看看
------解决方案--------------------
1、header 是不要的，因为你是以图片方式输出
2、你选用的字体是西文字体，没有汉字当然不能显示，你需要选一款中文字体
3、如果你的程序不是utf-8的，那么所有要输出的汉字都必须转成utf-8的
