Function Documentation

operator<<() [1/3]

std::ostream& operator<<	(	std::ostream &	o,
		const Histogram1D &	hist
	)

Show an histogram

The first column is the value associated to each histogram measure. The second one is the histogram measure.

Definition at line 115 of file histogram.cpp.

    aux.resize(hist.stepNo(), 2);
    FOR_ALL_ELEMENTS_IN_ARRAY1D(hist)

        A2D_ELEM(aux, i, 1) = A1D_ELEM(hist, i);
    }

operator<<() [2/3]

operator<<() [3/3]

std::ostream& operator<<	(	std::ostream &	o,
		const Histogram2D &	hist
	)

Show an histogram

The first column and second column are the (X,Y) coordinates of each histogram measure. The third one is the histogram measure.

Definition at line 545 of file histogram.cpp.
