	50	\brief Series for creating a candlestick chart.
	51
	52	QCandlestickSeries represents a series of data shown as candlesticks. The purpose of this class
	53	is to act as a container for single candlestick items. Each item is drawn to its own category
	54	when using QBarCategoryAxis. QDateTimeAxis and QValueAxis can be used as alternatives to
	55	QBarCategoryAxis. In this case, each candlestick item is drawn according to its timestamp value.
	56
	57	\note The timestamps must be unique within a QCandlestickSeries. When using QBarCategoryAxis,
	58	only the first one of the candlestick items sharing a timestamp is drawn. If the chart includes
	59	multiple instances of QCandlestickSeries, items from different series sharing a timestamp are
	60	drawn to the same category. When using QValueAxis or QDateTimeAxis, candlestick items sharing a
	61	timestamp will overlap each other.
	62
	63	See the \l {Candlestick Chart Example} {candlestick chart example} to learn how to create
	64	a candlestick chart.

		57	HCandlestickModelMapper allows the use of a QAbstractItemModel-derived model with data in rows
		58	as a data source for a candlestick series. It's possible to manipulate the data either through
		59	QAbstractItemModel or QCandlestickSeries.
		60
		61	The following QML example creates a candlestick series with three candlestick sets (assuming the
		62	model has at least four rows). Each candlestick set would contain data defined by timestamp,
		63	open, high, low and close columns. The name of a set would be defined by the vertical header of
		64	the row.

		31	\example candlestickchart
		32	\title Candlestick Chart Example
		33	\ingroup qtcharts_examples
		34
		35	\brief Shows how to create a candlestick chart.
		36
		37	\image examples_candlestickchart.png
		38
		39	To display a candlestick chart, we start by creating QCandlestickSeries to handle daily data. We
		40	are also specifying custom increasing and decreasing body colors.
		41
		42	\snippet candlestickchart/main.cpp 1
		43
		44	QFile is used for accessing a text file where the non-continuous data is kept. The
		45	\c CandlestickDataReader is an auxiliary class for reading the text file and finding the open,
		46	high, low, close, and timestamp values from the data. The \c CandlestickDataReader is explained
		47	in more detail later. The method \c readCandlestickSet() reads the values and sets them to the
		48	QCandlestickSet item which the method returns for the caller. The returned QCandlestickSet item
		49	is added to the series. We are also saving custom categories list for later use.
		50
		51	\snippet candlestickchart/main.cpp 2
		52
		53	Below, a new QChart instance is created and the previously created series object is added to it.
		54	We also define a title, and set an animation as
		55	\l {QChart::AnimationOption} {QChart::SeriesAnimation}.
		56
		57	\snippet candlestickchart/main.cpp 3
		58
		59	Here, we ask the chart to create default axes for our presentation. Then, we set custom
		60	categories for the horizontal axis by querying the pointer for the axis from the chart, and then
		61	setting the categories from previously saved custom categories list. We also set the range for
		62	the vertical axis by querying the pointer for the axis from the chart, and then setting the min
		63	and max values for that axis.
		64
		65	\snippet candlestickchart/main.cpp 4
		66
		67	Below, we set the legend to be visible and place it at the bottom of the chart.
		68
		69	\snippet candlestickchart/main.cpp 5
		70
		71	Finally, we add the chart onto a view. We also turn on the antialiasing for the chartView.
		72
		73	\snippet candlestickchart/main.cpp 6
		74
		75	The chart is ready to be shown. We set the chart to be the central widget of the window. We also
		76	set the size for the chart window and show it.
		77
		78	\snippet candlestickchart/main.cpp 7
		79
		80	Here, the method \c readCandlestickSet() is explained in detail. First, a line is read from
		81	the file, rejecting any lines starting with # as they are considered comment lines.
		82
		83	\snippet candlestickchart/candlestickdatareader.cpp 1
		84
		85	In the file, the data is arranged as a space-delimited sequence of numbers. On this snippet the
		86	line is split into single number strings which are stored in a QStringList.
		87
		88	\snippet candlestickchart/candlestickdatareader.cpp 2
		89
		90	To select values from the continuous data, following code is used. The values in a \c strList
		91	are stored in the following order: timestamp, open, high, low, close.
		92
		93	\snippet candlestickchart/candlestickdatareader.cpp 3
		94
		95	Finally, the following snippet shows how to create a new QCandlestickSet and provide it with all
		96	the necessary values.
		97
		98	\snippet candlestickchart/candlestickdatareader.cpp 4
