Detailed Description

Abstract base class providing plot and labeling functionality for functions F:X->Y.

Override mpFX::GetY to implement a function. Override mpFX::GetMinY and mpFX::GetMaxY to provide min and max Y range Optionally implement a constructor and pass a name (label) and a label alignment to the constructor mpFX::mpFX. If the layer name is empty, no label will be plotted.

Constructor & Destructor Documentation

◆ mpFX()

mpFX::mpFX	(	const wxString &	name = `wxEmptyString`,
		int	flags = `mpALIGN_RIGHT`,
		bool	useY2Axis = `false`
	)

Parameters

name	Label
flags	Label alignment, pass one of #mpALIGN_RIGHT, #mpALIGN_CENTER, #mpALIGN_LEFT.

Member Function Documentation

◆ DoPlot()

void mpFX::DoPlot	(	wxDC &	dc,
		mpWindow &	w
	)

protectedvirtual

Layer plot handler.

This implementation will plot the function in the visible area and put a label according to the alignment specified.

Implements MathPlot::mpLayer.

◆ GetY()

virtual double MathPlot::mpFX::GetY ( double x )

pure virtual

Get function value for argument.

Override this function in your implementation.

Parameters

x Argument

Returns: Function value

Implemented in Fibonacci, Elias, Optimum, FixedBitwidth, MyPower, MyFunction, and MySIN.
