mpFXY Class Reference

---

Detailed Description

Abstract base class providing plot and labeling functionality for a locus plot F:N->X,Y.

Locus argument N is assumed to be in range 0 .. MAX_N, and implicitly derived by enumerating all locus values. Override mpFXY::Rewind and mpFXY::GetNextXY to implement a locus. Optionally implement a constructor and pass a name (label) and a label alignment to the constructor mpFXY::mpFXY. If the layer name is empty, no label will be plotted.

virtual bool mpFXY::GetNextXY	(	double &	x,
		double &	y
	)		[pure virtual]

Get locus value for next N.

Override this function in your implementation.

Parameters:

x	Returns X value
y	Returns Y value

Implemented in mpFXYVector.

virtual void mpFXY::Plot	(	wxDC &	dc,
		mpWindow &	w
	)		[virtual]

Layer plot handler.

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

Implements mpLayer.

virtual void mpFXY::Rewind

(

)

[pure virtual]

Rewind value enumeration with mpFXY::GetNextXY.

Override this function in your implementation.

Implemented in mpFXYVector.

void mpFXY::UpdateViewBoundary	(	wxCoord	xnew,
		wxCoord	ynew
	)		[protected]

Update label positioning data.

Parameters:

xnew	New x coordinate
ynew	New y coordinate
