23 \brief A class which draws a coordinate grid
24
25 The QwtPlotGrid class can be used to draw a coordinate grid.
26 A coordinate grid consists of major and minor vertical
27 and horizontal gridlines. The locations of the gridlines
28 are determined by the X and Y scale divisions which can
29 be assigned with setXDiv() and setYDiv().
30 The draw() member draws the grid within a bounding
31 rectangle.
