Candlestick And OHLC (open/high/low/close) charts
Cartesian chart component can display both candlestick and OHLC graphs. Click on radio button to change the type to OHLC. If you zoom out, the graph will change to a line at a certain level of zoom. This is done because candlesticks become unusable when there are too many of them. This is not a built-in feature, but it is easily achievable with a simple script. When you zoom in, the chart dispatches an event specifying start and end indices of the selection. The script checks the difference between these indices, and if it is bigger than 100, changes graph type to "line".
