A special data structure must be provided when creating stock charts. When a com.sun.star.chart.StockDiagram is set as the current chart type, the data is interpreted in a specific manner depending on the properties Volume and UpDown. The following table shows what semantics are used for the data series.

Volume	UpDown	Series 1	Series 2	Series 3	Series 4	Series 5
false	false	Low	High	Close	-	-
true	false	Volume	Low	High	Close	-
false	true	Open	Low	High	Close	-
true	true	Volume	Open	Low	High	Close

For example, if the property Volume is set to false and UpDown to true, the first series is interpreted as the value of the stock when the stock exchange opened, and the fourth series represents the value when the stock exchange closed. The lowest and highest value during the day is represented in series two and three, respectively.
