Member Function Documentation

setData()

template<typename T >

void DISPLIB::Bar::setData	(	const Eigen::Matrix< T, Eigen::Dynamic, 1 > &	matClassLimitData,
		const Eigen::Matrix< int, Eigen::Dynamic, 1 > &	matClassFrequencyData,
		int	iPrecisionValue
	)

Sets new data to the bar chart using QtCharts

Parameters

[in]	matClassLimitData	vector input filled with class limits.
[in]	matClassFrequencyData	vector input filled with class frequency to the corresponding class.
[in]	iPrecisionValue	user input to determine the amount of digits of coefficient shown in the histogram.

Definition at line 159 of file bar.h.

splitCoefficientAndExponent()

template<typename T >

void DISPLIB::Bar::splitCoefficientAndExponent	(	const Eigen::Matrix< T, Eigen::Dynamic, Eigen::Dynamic > &	matClassLimitData,
		int	iClassAmount,
		Eigen::VectorXd &	vecCoefficientResults,
		Eigen::VectorXi &	vecExponentValues
	)

splitCoefficientAndExponent takes in QVector value of coefficient and exponent (example: 1.2e-10) and finds the coefficient (1.2) and the appropriate exponent (-12), normalize the exponents to either the lowest or highest exponent in the list then places the values in two separate QVectors

Parameters

[in]	matClassLimitData	vector input filled with values of class limits (in coefficient and exponent form).
[in]	iClassCount	user input to determine the amount of classes in the histogram.
[out]	vecCoefficientResults	vector filled with values of coefficient only.
[out]	vecExponentResults	vector filled with values of exponent only.

Definition at line 228 of file bar.h.

updatePlot()

template<typename T >

void DISPLIB::Bar::updatePlot	(	const Eigen::Matrix< T, Eigen::Dynamic, Eigen::Dynamic > &	matClassLimitData,
		const Eigen::Matrix< int, Eigen::Dynamic, Eigen::Dynamic > &	matClassFrequencyData,
		int	iPrecisionValue
	)

Updates the bar plot with the new data

Parameters

[in]	matClassLimitData	vector input filled with class limits.
[in]	matClassFrequencyData	vector input filled with class frequency to the corresponding class.
[in]	iPrecisionValue	user input to determine the amount of digits of coefficient shown in the histogram.
