service StockDiagram
Description specifies a diagram which can be used for presenting stock quotes.
Note that the data must have a specific structure for stock
diagrams. Let us assume that data is interpreted, such that
series are taken from columns (see property
Diagram ::DataRowSource ). Then you need tables of
the following structures for different types:
Volume is false UpDown is false
Volume is true UpDown is false
Volume is false UpDown is true
Volume is true UpDown is true
Volume Open Low High Close … … … … …

Properties' Details
Volume
boolean Volume ;
Description indicates if a stock chart contains data representing the
volume of stocks.
The values of the volume are represented as columns like
those of a BarDiagram .
If this property is set to true , the values of the first
series of the chart data are interpreted as volume.
UpDown
boolean UpDown ;
Description indicates if a stock chart contains data representing the
value of stocks on the opening and closing date.
The difference will be indicated by bars. The color
of the bar will be significant for positive or negative
differences between open and closed data.
If this property is false , the values of the first
series (or second if StockDiagram ::Volume is
true ) of the chart data are interpreted as the day's lowest
value. The next series is interpreted as the day's highest
value, and the last series is interpreted as the closing
value.
If this property is set to true , one additional series
is needed with the opening value of the stocks. It is assumed
as the series before the series with the day's lowest
value.
