\brief 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. |
