详细描述

The standard (1:1) mapping class for axis numbering

构造及析构函数说明

Qwt3DLinearScale()

Qwt3DLinearScale::Qwt3DLinearScale ( )

protected

Applies Qwt3DLinearAutoScaler::execute() for autoscaling

参数

[out]	a	First major tic after autoscaling
[out]	b	Last major tic after autoscaling
	start	Scale begin
	stop	Scale end
	ivals	Requested number of major intervals

返回

Number of major intervals after autoscaling

成员函数说明

autoscale()

int Qwt3DLinearScale::autoscale ( double &  a, double &  b, double  start, double  stop, int  ivals  )

overrideprotectedvirtual

Autoscales the axis

参数

[out]	a	First major tic after applying autoscaling
[out]	b	Last major tic after applying autoscaling
	start	Scale begin
	stop	Scale end
	ivals	Requested number of major intervals

返回

Number of major intervals after autoscaling

The default implementation sets a=start, b=stop and returns ivals.

calculate()

void Qwt3DLinearScale::calculate ( )

overrideprotectedvirtual

Creates the major and minor vector for the scale

实现了 Qwt3DScale.

clone()

Qwt3DScale * Qwt3DLinearScale::clone ( ) const

overrideprotectedvirtual

Returns a new heap based object utilized from Qwt3DClonePtr

返回

A new Qwt3DLinearScale copy

实现了 Qwt3DScale.
