Member Function Documentation

AddData()

void mpChart::AddData	(	const double &	data,
		const std::string &	label
	)

Add data and label.

Parameters

data
label

Clear()

void mpChart::Clear ( )

virtual

Clears all the data, leaving the layer empty.

See also

SetBarValues, SetBarLabels

HasBBox()

virtual bool MathPlot::mpChart::HasBBox ( )

inlinevirtual

Check whether this layer has a bounding box.

The default implementation returns TRUE. Override and return FALSE if your mpLayer implementation should be ignored by the calculation of the global bounding box for all layers in a mpWindow.

Return values

TRUE	Has bounding box
FALSE	Has not bounding box

Reimplemented from MathPlot::mpLayer.

SetChartLabels()

void mpChart::SetChartLabels

(

const std::vector< std::string > &

labelArray

)

Set bar label values.

Parameters

labelArray

Vector of strings containing labels.

SetChartValues()

void mpChart::SetChartValues

(

const std::vector< double > &

data

)

Set bar values.

Parameters

data	Vector of double.
