你可以通过使一些或所有标记可见来突出显示折线迷你图中的各个数据标记（值）。
showFirst: 迷你图组中的每一个迷你图的第一个数据点的的格式是否不同。
showHigh: 迷你图组中的每一个迷你图的最高点所对应的数据点的格式是否不同。
showLast: 迷你图组中的每一个迷你图的最末点所对应的数据点的格式是否不同。
showLow: 迷你图组中的每一个迷你图的最低点所对应的数据点的格式是否不同。
showNegative: 迷你图组中的每一个迷你图的负数数据点的格式是否不同。
showMarkers: 迷你图组中的每一个迷你图的数据标记是否显示。
你可以通过下面这些方法来设置迷你图的样式和格式：
axisColor: 轴线的颜色。
firstMarkerColor: 迷你图组中的每一个迷你图的第一个数据点的颜色。
highMarkerColor: 迷你图组中的每一个迷你图的最高数据点的颜色。
lastMarkerColor: 迷你图组中的每一个迷你图的最末数据点的颜色。
lowMarkerColor: 迷你图组中的每一个迷你图的最低数据点的颜色。
markersColor:迷你图组中的每一个迷你图的数据标记的颜色。
negativeColor: 迷你图组中的每一个迷你图的负数数据点的颜色。
seriesColor: 迷你图组中的每一个迷你图的颜色。
迷你图还提供了一些额外的配置。比如，当数据系列中有空值的时候，你可以使用 displayEmptyCellsAs 方法来控制是否显示空值。例如：
这个示例演示了如何应用这些配置：
