This class is a subclass of IlvSingleScaleDisplayer that allows you to display a scale with a straight-line axis.

| ) |
Constructor.
Initializes a new IlvRectangularScaleDisplayer object.
| coordInfo | The coordinate information to which the scale is connected. |
| defaultPalette | The default palette used to draw the various parts of the scale (axis, step labels, axis label). Each individual part can be assigned a different palette afterwards. |

| IlUInt | nbSteps, | ||
| const char *const * | stepLabels, | ||
| IlUInt | nbSubStepsBetween, | ||
| IlvPalette * | defaultPalette | ||
| ) |
Constructor.
Initializes a new IlvRectangularScaleDisplayer object.
| coordInfo | The coordinate information to which the scale is connected. |
| nbsteps | The number of major steps. |
| stepLabels | The labels of the major steps. |
| nbSubStepsBetween | The number of minor steps between two major steps. |
| defaultPalette | The default palette used to draw the various parts of the scale (axis, step labels, axis label). Each individual part can be assigned a different palette afterwards. |

virtual |
Factory method to create a default cursor.
The default implementation returns an instance of IlvRectangularChartCursor if the projector is Cartesian and an instance of IlvCircularChartCursor if the projector is polar.
| scaleRef | The scale that can be used as a reference for the created cursor to indicate where the cursor line must stop. |
Implements IlvSingleScaleDisplayer.
