Detailed Description¶
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 gridlines. The locations of the gridlines 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.Member Function Documentation¶
void QwtPlotGrid::draw (QPainter *painter, const QwtScaleMap &xMap, const QwtScaleMap &yMap, const QRect &canvasRect) const [virtual]¶
Draw the grid. The grid is drawn into the bounding rectangle such that gridlines 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 rect of the plot canvas
Implements QwtPlotItem.
