Detailed Description

2 dimensional function plot

Function plot graph with discrete x scale and continous y scale This makes it possible to display "#x" samples

Constructor & Destructor Documentation

graphModel()

lmms::graphModel::graphModel	(	float	_min,
		float	_max,
		int	_size,
		Model *	_parent,
		bool	_default_constructed = false,
		float	_step = 0.0 )

Constructor.

Parameters

_min	Minimum y value to display
_max	Maximum y value to display
_size	Number of samples (e.g. x value)
_step	Step size on y axis where values snap to, or 0.0f for "no snapping"
