Candlestick chart is one of the most common ways to display financial data such as stock trading prices over time. Creating candlestick charts with amCharts is really easy and you get a lot of advanced features such as grouping right out of the box (try zooming in and out).
Key implementation details
To create a candlestick chart we add
CandlestickSeries to an
XYChart. We configure all the value fields for open/close/low/high values and also for grouping (
lowValueYGrouped, etc.). We enable grouping by setting
true on the
DateAxis (X axis in this demo). And the engine takes care of the rest.
