Drawing tools and annotations include vertical range annotations that span an entire plot height, making them ideal for highlighting time-based events such as recessions, earnings seasons, or crisis periods across multiple chart panels.
This sample displays S&P 500 daily candlesticks on a primary plot with a MACD indicator on a second panel. Synchronized vertical range annotations on both plots highlight the October 2007 to March 2009 bear-market period, providing clear event-focused context. An area scroller with range picker/selector controls enables interactive comparison of the annotated window against surrounding years.
