template<class T , class SX , class SY , class SE >

T& pgplot::pgaff::errb	(	T &	dev,

		const SY &	y,
		const SE &	e,
		const Eerrdir &	dir = Fdirver,
		const float &	t = 1.
	)

draw error bars from series

This implements cpgerrb functionality.

Parameters

dev	device to be plotted on
x	series of x-coordinates
y	corresponding series of y-coordinates
e	corresponding series of error bars
t	length of terminals to be drawn
SX	series class for x
SY	series class for y
SE	series class for e
T	pgplot device class

Returns

returns a reference to the device context
