How to put $MyData->addpoints (Array (150,220,300,250,420,200,300,200,100), "test"), the string test is displayed in Chinese, how to $MyData Setaxisname (0, "Hits"), display Chinese, such as $MyData->setaxisname (0, "set");
------Solution--------------------
Is it not possible to write directly in Chinese?
------Solution--------------------
Comment out the header ("content-type:text/html; Charset=utf-8 ");
------Solution--------------------
Is it the latest version?
See you later, next.
------Solution--------------------
1, the header is not, because you are the image of the way out
2, you choose the font is a Western text body, no Chinese characters can not be displayed, you need to choose a Chinese font
3, if your program is not utf-8, then all the characters to be exported must be converted into Utf-8
