你可以给迷你图分组，同一分组中的迷你图可以共享一些通用的设置。 你可以使用 groupSparkline 和 ungroupSparkline 方法来分组或者取消分组。例如：
你可以使用 sparklineType 方法来改变迷你图的类型。比如：
你也可以使用 data 方法来获取或者设置数据。使用 dataOrientation 方法来获取或者设置数据方向。使用 dateAxisData 方法来自定制迷你图的数据轴数据。 使用 dateAxisOrientation 方法来获取或者设置轴方向。使用 displayDateAxis 方法来获取或者设置是否显示数据轴。例如：
因为迷你图可供设置的配置还有很多，你可以使用 setting 方法来获取或者设置这些迷你图的更多配置。 例如：
当迷你图被设定为一组是，同组中的迷你图将共享统一的设置，接下来，你会看到如何应用迷你图的设置.
迷你图提供了一个事件，这个事件在迷你图变化的时候会被触发。例如：
