Candlestick: JavaScript Data Grid Demo

Open, high, low and close, one row a day

type: 'candlestick', measures: [open, high, low, close]

This draws a candlestick chart, one candle a day from open, high, low and close, with a price axis on the right, zoom and pan, and a drawing rail for trend lines, channels, Fibonacci retracements and measuring a range. It shows a market's daily range and direction in the form traders read, straight from the grid's rows.
