Hi all,

I am wondering hoow to properly use setSymbolExtent on a QwtPlotTradingCurve. I started from the stockchart example, where the value is defined as 12 * 500 * 1000.0 with this comment:
Qt Code: 
  1. // as we have one sample per day a symbol width of 12h avoids overlapping symbols
To copy to clipboard, switch view to plain text mode 

So, what does 500 and 1000.0 stand for? How could I use setSymbolExtent to have a "good" view of my candlestick chart? By good I mean no overlapping candles whatever the number of candles is.

Note that I am aware of this thread, but it is still not answered, and that I do not have a QwtScaleWidget.

Hope you could help.

Best regards
