The candlesticks style is only relevant for 2-d data plotting of financial
data. Five columns of data are required; in order, these should be the x
coordinate (most likely a date) and the opening, low, high, and closing
prices. The symbol is an open rectangle, centered horizontally at the x
coordinate and limited vertically by the opening and closing prices. A
vertical line segment at the x coordinate extends up from the top of the
rectangle to the high price and another down to the low. The width of the
rectangle may be changed by set bar. The symbol will be unchanged if the
low and high prices are interchanged or if the opening and closing prices
are interchanged. See set bar and financebars.
