  dataset.addValue(300, "上海", "葡萄");
  dataset.addValue(300, "广州", "葡萄");
  dataset.addValue(400, "北京", "香蕉");
  dataset.addValue(400, "上海", "香蕉");
  dataset.addValue(400, "广州", "香蕉");
  dataset.addValue(500, "北京", "荔枝");
  dataset.addValue(500, "上海", "荔枝");
  dataset.addValue(500, "广州", "荔枝");
  return dataset;
 }
}

 

症状：

导出图片后一堆方框，乱码，分析后认为没有设置字符集

解决办法：

并不需要设置字符集，只要设置字体也可以，用ＦＯＮＴ类
