HighLowOpenClose charts
The HLOCChart control represents financial data as a series of lines representing the high,
low, opening, and closing values of a data series. The top and bottom of the vertical line
represent the high and low values for the data point, while the left tick mark represents the
opening values and the right tick mark represents the closing values.
The HLOCChart control does not require a data point that represents the opening value. A
related chart is the CandlestickChart control that represents similar data as candlesticks. You
use the HLOCSeries with the HLOCChart control to define the data for
HighLowOpenClose charts. The following example shows a HighLowOpenClose chart:

connected by a continuous line. You can use an icon or symbol to represent each data point
along the line, or show a simple line without icons.
