plotOptions.vwap.gapSize

Defines when to display a gap in the graph, together with the gapUnit option.

In case when dataGrouping is enabled, points can be grouped into a larger time span. This can make the grouped points to have a greater distance than the absolute value of gapSize property, which will result in disappearing graph completely. To prevent this situation the mentioned distance between grouped points is used instead of previously defined gapSize.

In practice, this option is most often used to visualize gaps in time series. In a stock chart, intraday data is available for daytime hours, while gaps will appear in nights and weekends.
