Detailed Description

A chart class.

Library: dbchart

The class defines a chart graphic which can be connected to one or several data sources. The number of data sources and columns depend on the data model. By default, three data models are provided:

By row: Each row contains the data for one point from a series.
By column: Each row contains a point for each series.
By data source: Each data source contains all points for a series.

However, you can define your own data model. This classes uses another model type, the series model. This model type, is used to compute the properties of the new series. The computed properties are:

The displayer, by default it is the default displayer.
The color, by color, it is computed.

Note: The inspector of this class has two limitations:

You can not define a chart graphic without displayer.
You can not define a chart graphic without data set.

See Also: IliChartDataModel, IliChartSeriesModel.

Constructor & Destructor Documentation

IliChartGraphic::IliChartGraphic	(	IlvDisplay *	display,
		const IlvRect &	bbox,
		IlvPalette *	palette = `0`
	)

Constructor of the IliChartGraphic class.

Initializes an IliChartGraphic object. This class can be used to connect a data source to chart graphic.

Parameters

display	The display.
bbox	The bounding box.
palette	The palette.

Member Function Documentation

void IliChartGraphic::addColumnName	(	const char *	name,
		IlInt	dsi = `0`
	)

Adds a column name.

This function works fine when the data model allows this operation.

Parameters

name	The column name.
dsi	The data source index.

void IliChartGraphic::addErrorSink ( IliErrorSink * sink )

Forwards an error message to all the error sinks that have been added with the addErrorSink member function.

Parameters

msg	The error message.

IlInt IliChartGraphic::getColumnCount ( IlInt dsi = 0 ) const

Returns the column count.

Parameters

dsi	The data source index.

Returns: The column count.

const char* IliChartGraphic::getColumnName	(	IlInt	pos,
		IlInt	dsi = `0`
	)		const

Returns a column name.

Parameters

pos	The column position.
dsi	The data source index.

Returns: The column name or 0 if the indexes are invalid.

IliChartDataModel* IliChartGraphic::getDataModel ( ) const

Returns the data model.

Returns: The data model.

const char* IliChartGraphic::getDataModelName ( ) const

Returns the data model name.

Returns: The model name.

IliDataSource* IliChartGraphic::getDataSource ( IlInt index = 0 )

Returns a data source.

Parameters

index The data source index.

Returns: The data source if the index parameter is valid, otherwise returns 0

IlInt IliChartGraphic::getDataSourceCount ( ) const

Returns the data source count.

Returns: The count.

const char* IliChartGraphic::getDataSourceName ( IlInt index = 0 ) const

Returns a data source name.

Parameters

index The data source index.

Returns: The data source name if the index parameter is valid, otherwise returns 0

IlvAbstractChartDisplayer* IliChartGraphic::getDefaultDisplayer ( ) const

Returns the default displayer.

Returns: The displayer.

IliErrorReporter* IliChartGraphic::getErrorReporter ( ) const

Returns the error reporter that is used by the reportErrors member functions.

When this property is NULL a default error reporter is used. Initially this property is NULL.

Returns: The error reporter.

IlInt IliChartGraphic::getModelPropertyCount ( IliChartModelType type ) const

Returns the model property count.

Parameters

type	The model type.

Returns: The count.

IlInt IliChartGraphic::getModelPropertyIndex	(	IliChartModelType	type,
		const char *	name
	)		const

Returns a model property index.

Parameters

type	The model type.
name	The property name.

Returns: The index if found, otherwise -1.

const char* IliChartGraphic::getModelPropertyName	(	IliChartModelType	type,
		IlInt	index
	)		const

Returns a model property name.

Parameters

type	The model type.
index	The property index.

Returns: The name if index valid, otherwise 0.

const IliValue& IliChartGraphic::getModelPropertyValue	(	IliChartModelType	type,
		const char *	name
	)		const

Returns a model property value.

Parameters

type	The model type.
name	The property name.

Returns: The value if found otherwise a null value.

const IliValue& IliChartGraphic::getModelPropertyValue	(	IliChartModelType	type,
		IlInt	index
	)		const

Returns a model property value.

Parameters

type	The model type.
index	The property index.

Returns: The value if found otherwise a null value.

IliChartSeriesModel* IliChartGraphic::getSeriesModel ( ) const

Returns the series model.

Returns: The series model.

const char* IliChartGraphic::getSeriesModelName ( ) const

Returns the series model name.

Returns: The model name.

void IliChartGraphic::removeErrorSink ( IliErrorSink * sink )

Removes an error sink from this table gadget.

Parameters

sink	The error sink.

void IliChartGraphic::reportErrors ( const IliErrorList & ) const

Reports the errors that are contained in a error list.

This member function makes use of the error reporter returned by getErrorReporter if any. Otherwise it uses a default error reporter.

Parameters

errorlist The error list.

void IliChartGraphic::setColumnCount	(	IlInt	count,
		IlInt	dsi = `0`
	)		const

Sets the column count.

This function works fine when the data model allows this operation.

Parameters

count	The column count.
dsi	The data source index.

void IliChartGraphic::setColumnName	(	const char *	name,
		IlInt	pos,
		IlInt	dsi = `0`
	)

Sets a column name.

Parameters

name	The column name.
pos	The column position.
dsi	The data source index.

void IliChartGraphic::setDataModelName ( const char * name )

Sets the data model name.

When you change the data model name, the data source name and the column name are erased.

Parameters

name	The model name. The predefined models are: IliChartRowDataModel, IliChartDSDataModel, IliChartColumnDataModel

void IliChartGraphic::setDataSource	(	IliDataSource *	ds,
		IlInt	index = `0`
	)

Sets a data source.

Parameters

ds	The data source.
index	The data source index.

void IliChartGraphic::setDataSourceCount ( IlInt count )

Sets the data source count.

If the data model has a data source count fixed, this function do nothing. If the data source count is changed, all columns are erased.

Parameters

count The data source count.

void IliChartGraphic::setDataSourceName	(	const char *	name,
		IlInt	index = `0`
	)

Sets a data source name.

Parameters

name	The data source name.
index	The data source index.

void IliChartGraphic::setDefaultDisplayer ( IlvAbstractChartDisplayer * disp )

Sets the default displayer.

The default displayer is used to create a displayer for new series without displayer. The default displayer is deleted by the IliChartGraphic class. The color of the default displayer is ignored by the chart graphic. It is computed by the current series model.

Parameters

disp	The default displayer.

void IliChartGraphic::setErrorReporter ( IliErrorReporter * reporter )

Sets the error reporter.

Note that the table gadget will not delete the error reporter at destruction time, so the same error reporter may be safely shared by many table gadgets.

Parameters

reporter The new error reporter.

void IliChartGraphic::setModelPropertyValue	(	IliChartModelType	type,
		const char *	name,
		const IliValue &	val
	)

Sets a model property value.

Parameters

type	The model type.
name	The property name.
val	The value.

void IliChartGraphic::setModelPropertyValue	(	IliChartModelType	type,
		IlInt	index,
		const IliValue &	val
	)

Sets a model property value.

Parameters

type	The model type.
index	The property index.
val	The value.

void IliChartGraphic::setSeriesModelName ( const char * name )

Sets the series model name.

Parameters

name	The model name. The predefined model is IliChartSeriesModel.
