5 columns: date open low high close
The symbol is a vertical line segment, located horizontally at the x coordinate and limited vertically by the high and low prices. A horizontal tic on the left marks the opening price and one on the right marks the closing price. The length of these tics may be changed by set errorbars. The symbol will be unchanged if the high and low prices are interchanged. See set errorbars and candlesticks, and also the finance demo.
