.SH "Detailed Description"
.PP 
\fBQwtPlotTradingCurve\fP illustrates movements in the price of a financial instrument over time\&. 

\fBQwtPlotTradingCurve\fP supports candlestick or bar ( OHLC ) charts that are used in the domain of technical analysis\&.
.PP
While the length ( height or width depending on \fBorientation()\fP ) of each symbol depends on the corresponding OHLC sample the size of the other dimension can be controlled using:
.PP
.IP "\(bu" 2
\fBsetSymbolExtent()\fP
.IP "\(bu" 2
setSymbolMinWidth()
.IP "\(bu" 2
setSymbolMaxWidth()
.PP
.PP
The extent is a size in scale coordinates, so that the symbol width is increasing when the plot is zoomed in\&. Minimum/Maximum width is in widget coordinates independent from the zoom level\&. When setting the minimum and maximum to the same value, the width of the symbol is fixed\&.
