详细描述

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

构造及析构函数说明

LinearScale()

LinearScale::LinearScale ( )

protected

Applies LinearAutoScaler::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 Qwt3D::LinearScale::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.

重载 Qwt3D::Scale .

实现了 Qwt3D::Scale.

clone()

Scale * LinearScale::clone ( ) const

overrideprotectedvirtual

Returns a new heap based object utilized from ClonePtr

返回
