Implementation of predefined Cartesian charts.
Library: ilvcharts
This class is a subclass of IlvChartGraphic which allows you to display a Cartesian chart.
A Cartesian chart represents data in a standard way: the data are expressed in Cartesian coordinates (x, y). The abscissa and ordinate scales which represent the x-and y-coordinates, respectively, are orthogonal.
Example of a Cartesian chart:
IlvChartGraphic. | IlvCartesianChart::IlvCartesianChart | ( | IlvDisplay * | display, |
| const IlvRect & | bbox, | ||
| IlBoolean | useGrid = IlFalse, |
||
| IlvCartesianProjector::Orientation | orientation = IlvCartesianProjector::IlvXRightYTop, |
||
| IlvPalette * | palette = 0, |
||
| IlvPalette * | gridPalette = 0 |
||
| ) |
Constructor.
Initializes a new IlvCartesianChart object. The constructor creates a Cartesian chart with two default scales. The associated projector is an instance of IlvCartesianProjector and the scales are instances of IlvRectangularScaleDisplayer.
| display | The display connection that will handle the drawing of this object. |
| bbox | The initial bounding box of the chart graphic. |
| useGrid | A Boolean indicating whether grids should be added to the created scales. |
| orientation | The orientation of the Cartesian projector. |
| palette | The palette associated with the chart. |
| gridPalette | The palette associated with the grids (meaningful only if useGrid is equal to IlTrue). |
