An OHLC/HLC line series is basically a line series, the only noticeable difference is the
number of values associated with each data point. An OHLC/HLC line series is primarily
intended to be used in the stock market, displaying prices evolution against time. The line
displayed corresponds to only one of the values associated with a data point, the 'close'
value, although the remaining values(open,high,low or just high and low) are presented
inside tooltips, small popup windows displayed when mouse cursor hovers over a data
point. One topic of this tutorial explains the usage of tooltips.
There are parameters to specify the thickness, style(solid or dashed) and a few other properties.
Any OHLC series type is 'ohlc'. To specify an OHLC/HLC line series the parameter
seriex_type must be passed values 2 or 3, to identify an OHLC or HLC line series,
respectively.
The number of values passed to the seriex_values parameter must always be a multiple
of 4. Every sequential set of 4 values is assigned to one data point, corresponding to the
open, high, low and close values.
