导出后，我们会在图表中添加一些额外的文字title。但是，这有效，文本格式不符合我的想法。选择框中的title代码：
title: { text: '<span style="text-align:center; font-weight:bold;">Labor Force, Employment and Unemployment for Florida in Multiple Time Periods</span><br /><br /><span style="text-align:center; font-weight:bold;font-size:9pt">Labor Force Area Distribution Graph</span><br /><br /><span style="text-align:left; font-size:10px">The graph below shows the Counties in Florida with the highest monthly not seasonally adjusted unemployment rate in June, 2013.</span>' }
相关文字为<span style="text-align:left; font-size:10px">The graph below shows the Counties in Florida with the highest monthly not seasonally adjusted unemployment rate in June, 2013.</span>。这不是左对齐的，当它转到新行时它也有一个额外的大换行符。
这是一个实时example。
