void Plot2d_HistogramItem::draw ( QPainter *  thePainter,
const QwtScaleMap &  theXMap,
const QwtScaleMap &  theYMap,
const QRectF &   
) const
virtual

Draws histogram object

Reimplemented from Plot2d_HistogramQwtItem.

void Plot2d_HistogramItem::drawRectAndLowers ( QPainter *  thePainter,
Qt::Orientation  theOr,
const QRect &  theRect 
) const
protected

Draws bar of histogram and on it bars of histograms with lower height.

References Plot2d_HistogramQwtItem::drawBar(), getCrossedTop(), Horizontal, and myCrossed.

QList< QRect > Plot2d_HistogramItem::getBars ( ) const

Get histogram bar items

References myBarItems.

int Plot2d_HistogramItem::getCrossedTop ( const QRect &  theRect) const
protected

Returns top value of the given rect in the context of other bars.

It's necessary to remember, that theRect has inverted coordinate Y.

References getBars().

bool Plot2d_HistogramItem::isCrossItems ( ) const

Get "cross items" option

References myCrossed.

void Plot2d_HistogramItem::setCrossItems ( bool  theCross)

Set/clear "cross items" option

References myCrossed.

void Plot2d_HistogramItem::updateLegend ( QwtPlotItem *  thePlotItem,
QList< QwtLegendData > &  theLegendData 
)
virtual

Set to legend item symbol with color of item

References Plot2d_HistogramQwtItem::color(), Plot2d_SelectableItem::isSelected(), and Plot2d_SelectableItem::legendPen().
