Detailed Description

Object for linear interpolated or step broken curve or bar graph drawing.

By default curve does not have attached data, so one need to attachData() to see some drawings.

LinearCurve mode of interpolation

BarGraph mode of interpolation

Member Data Documentation

ZqbNatGrpMember ZqCurve::m_Arg

Bounds for argument values and access to natural group.

bool ZqCurve::m_bAutoSort

protected

Direction of function argument axis.

double ZqCurve::m_fBaseFuncLevel

protected

Base level of function drawing.

double ZqCurve::m_fSpaceBetweenBars
