Candlestick charts visualise price movement using Open, High, Low, and Close values, making them a fundamental tool for trading systems, financial analytics platforms, and time-series applications.
Frequently Asked Questions
Q: What is a candlestick chart in JavaScript?
A: A candlestick chart displays price movement over time using OHLC (Open, High, Low, Close) data, making it one of the most widely used chart types for financial analysis and trading applications.
Q: Why use CategoryAxis for candlestick charts?
A: CategoryAxis provides consistent spacing between candles, ensuring financial data is displayed clearly even when time intervals are irregular.
