echart 坐标轴字体部分倾斜
在项目中遇到了报表的模块，针对这一块使用了echart 插件。但是在客户有一个特殊需求
如下的图片，坐标轴部分倾斜
让上图 印度和美国变成红色好处理，echarts中有对应方法，先给出变红色的html代码

但是没有设置部分倾斜的方法。无奈只能找源码，进行修改。
在源码中的 function buildAxisLabel(axisBuilder, axisModel, opt) 这个function中可以看到
但是运行后你会看到提示fontStyle 未定义，就是自己加点这个fontStyle未定义。
没关系，没定义，我们定义就是了
至此，完成。
修改完源码后在加入需要设置的fontStyle即可，再给出，最终的html代码
