Stock event markers are visual annotations added to a financial chart timeline to call out notable dates and developments. With AnyChart you can load marker groups from JSON, choose marker types like pin or flag, and anchor them to specific series values for precise placement.
This sample charts the USD/Bitcoin exchange rate as a range-area series and overlays multiple grouped event markers loaded from an external JSON file. The markers use the pin type and are positioned at the series high values, providing clear context without obscuring the data. A volume-based scroller, hover styling for markers, range picker, and range selector complete the interactive experience.
See the Event Markers documentation for all configuration options.
