//from doc
//When the canvas has to be redrawn, the Paint function of each objects in the pad is called.
//In case of histograms, TH1::Paint invokes directly THistPainter::Paint.
//
// Yes, TCanvasStock::Update()
//      => THistPainterStock Constructor
//      => THistPainterStcok::Paint()

//Can be used in two ways:
// 1. derive HistPainterStock from HistPainter, keep all default values, choosen version until now
// 2. derive .. directly from TVirtualHistPainter, need to rewrite a lot more, (more flexible ?)
//      not sure because I can overload all functions I want, like reading options...
//      deriving allow to set up by default all members not used

//In fact quite general and flexible
// can use it only for drawing candle DataCSV data
// could keep for default painting for all indicators, need more work, more function to rewrite
// should implement for e.g. 30-70 for particular indicator, can be added as function in normal Paint, but more difficult for feedback (pass the limit ??), 
// much easier if different Paint, need structure in the code ( maybe a kind of new Hparam ?? )
//
// Object in separate class, here paint axis, frame, title..

/*
 * Bug with axis solved, 20/01/11
 * SetBinLabel called only by PaintCandle, so PaintAxis should be done after ! Seems logic, label assigned only to StockCSV 
 *             (what about StockdCSV ??)
 *
 * Of course should be done in PaintAxis(), need PaintAxis to set the new label, need a coherent way to design axis, graph and shift !!!
 * Could update the axis, e.g., shift graph to future
 *
