Base class for adjacent data displayers.
Library: ilvcharts
This class is a subclass of IlvCompositeChartDisplayer. This class is the base class for displayers representing data side by side. One subclass is provided that defines the child displayers that are created by default: IlvSideBySideBarChartDisplayer that displays bars side by side.
The side-by-side displayers display as many data sets as you want. The data items of the first data set are represented first. The data items of the second data set are represented by the side of the data items of the first data set. The data items of the third data set are represented by the side of the data items of the second data set and so on. The side-by-side displayers can be used with any type of projection. (See the IlvAbstractProjector class for more details.)
| IlvSideBySideChartDisplayer::IlvSideBySideChartDisplayer | ( | ) |
Constructor.
Initializes a new IlvSideBySideChartDisplayer object.
| IlvSideBySideChartDisplayer::IlvSideBySideChartDisplayer | ( | IlvAbstractChartDisplayer * | model, |
| IlUInt | count, | ||
| IlvPalette *const * | palettes = 0 |
||
| ) |
Constructor.
Initializes a new IlvSideBySideChartDisplayer object with count child displayers.
| model | The displayer model that will be used to create the child displayers. |
| count | The number of child displayers that are created. |
| palettes | The palettes that will be used by the created child displayers. If a valid array of palettes is provided, its size must match count. |
| IlvSideBySideChartDisplayer::IlvSideBySideChartDisplayer | ( | IlvChartDisplayerFactory * | factory, |
| IlUInt | count, | ||
| IlvPalette *const * | palettes = 0 |
||
| ) |
Constructor.
Initializes a new IlvSideBySideChartDisplayer object with count child displayers.
| factory | The displayer factory that will be used to create the child displayers. |
| count | The number of child displayers that are created. |
| palettes | The palettes that will be used by the created child displayers. If a valid array of palettes is provided, its size must match count. |
|
protectedvirtual |
Performs the updates needed when a real data set is removed.
This method removes the child displayer at the index index and then calls the IlvCompositeChartDisplayer::dataSetRemoved method.
| index | The index of the removed data set. |
Reimplemented from IlvAbstractChartDisplayer.
|
protectedvirtual |
Updates the displayers that compose the current displayer.
This method first calls the IlvCompositeChartDisplayer::updateDisplayers method and then sets the shift offset for each child displayer so that the child displayers can be displayed side by side. See the IlvSingleChartDisplayer::setShiftOffset and the IlvCompositeChartDisplayer::updateDisplayers methods for more details.
Reimplemented from IlvCompositeChartDisplayer.
