Detailed Description

The Diagram class is a superclass for diagrams.

Todo:: Should probably use QFontMetrics::boundingRect(QString).width instead of QFontMetrics::width(QString), since only the first gives the actual width (see Qt docs)

Constructor & Destructor Documentation

Diagram::Diagram	(	int	_cx = `0`,
		int	_cy = `0`
	)

Definition at line 53 of file diagram.cpp.

		double &	zD,
		double &	zDstep,
		double &	corr,
		int	len
	)		`[protected]`

Calculations for logarithmical Cartesian diagrams (RectDiagram and Rect3DDiagram).

Parameters:

Axis	- pointer to the axis to scale
len	- length of axis in pixel on the screen

Returns:: value: "true" if axis runs from largest to smallest value

Parameters:

[out]	z	- screen coordinate where the first grid is placed
[out]	zD	- number where the first grid is placed
[out]	zDstep	- number increment from one grid to the next
[out]	coor	- scale factor for calculate screen coordinate

Todo:: use this as example to document other methods
