.SH "Detailed Description"
.PP 
A class which draws a coordinate grid. 

The \fBQwtPlotGrid\fP 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 \fBsetXDiv()\fP and \fBsetYDiv()\fP. The \fBdraw()\fP member draws the grid within a bounding rectangle.
