Stock event markers are visual annotations placed on a financial chart timeline to flag important dates and news. AnyChart lets you create grouped event markers with custom formats, click handlers, and hover effects, making it easy to link chart data with external information.
This sample pairs an AAPL candlestick series with a sidebar feed of Apple financial news loaded from JSON. Each news entry becomes a grouped flag marker on the plot, labeled with a letter symbol. Clicking a marker opens the corresponding article, and hovering a sidebar item highlights its marker group on the chart. A volume-based scroller, range picker, and range selector round out the interactive navigation.
See the Event Markers documentation for all configuration options.
