Version 6.1.4                                    Wed Jan 2 2019                                   QwtPlotGrid(3)

       A class which draws a coordinate grid.

       The QwtPlotGrid class can be used to draw a coordinate grid. A coordinate grid consists of major and
       minor vertical and horizontal grid lines. The locations of the grid lines are determined by the X and Y
       scale divisions which can be assigned with setXDiv() and setYDiv(). The draw() member draws the grid
       within a bounding rectangle.

voidQwtPlotGrid::draw(QPainter*painter,constQwtScaleMap&xMap,constQwtScaleMap&yMap,constQRectF&canvasRect)const[virtual]
       Draw the grid. The grid is drawn into the bounding rectangle such that grid lines begin and end at the
       rectangle's borders. The X and Y maps are used to map the scale divisions into the drawing region screen.

       Parameters:painter Painter
           xMap X axis map
           yMap Y axis
           canvasRect Contents rectangle of the plot canvas

       Implements QwtPlotItem.

   voidQwtPlotGrid::enableX(boolon)
       Enable or disable vertical grid lines.

       Parameters:on Enable (true) or disable

           Minor grid lines can be enabled or disabled with enableXMin()voidQwtPlotGrid::enableXMin(boolon)
       Enable or disable minor vertical grid lines.

       Parameters:on Enable (true) or disable

       Seealso:enableX()voidQwtPlotGrid::enableY(boolon)
       Enable or disable horizontal grid lines.

   voidQwtPlotGrid::setMajorPen(constQColor&color,qrealwidth=0.0,Qt::PenStylestyle=Qt::SolidLine)
       Build and assign a pen for both major grid lines

       In Qt5 the default pen width is 1.0 ( 0.0 in Qt4 ) what makes it non cosmetic ( see QPen::isCosmetic() ).
       This method has been introduced to hide this incompatibility.

       Parameters:color Pen color
           width Pen width
           style Pen style

           pen(), brush()

   voidQwtPlotGrid::setMajorPen(constQPen&pen)
       Assign a pen for the major grid lines

       Parameters:pen Pen

       Seealso:majorPen(), setMinorPen(), setPen()voidQwtPlotGrid::setMinorPen(constQColor&color,qrealwidth=0.0,Qt::PenStylestyle=Qt::SolidLine)

       In Qt5 the default pen width is 1.0 ( 0.0 in Qt4 ) what makes it non cosmetic ( see QPen::isCosmetic() ).
