+## Customize Style Explicitly
 
 It is a common way to set style explicitly. Throughout ECharts [option](${optionPath}), style related options can be set in various place, including [itemStyle](${optionPath}series.itemStyle), [lineStyle](${optionPath}series-line.lineStyle), [areaStyle](${optionPath}series-line.areaStyle), [label](${optionPath}series.label), etc.

+## 直接的样式设置
 
 直接的样式设置是比较常用设置方式。纵观 ECharts 的 [option](${optionPath}) 中,很多地方可以设置 [itemStyle](${optionPath}series-bar.itemStyle)、[lineStyle](${optionPath}series-line.lineStyle)、[areaStyle](${optionPath}series-line.areaStyle)、[label](${optionPath}series-bar.label) 等等。这些的地方可以直接设置图形元素的颜色、线宽、点的大小、标签的文字、标签的样式等等。
