| 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.
