An object designed at drawing a set of points. It does not own its data, but keeps references to them (they must be double arrays)

Instance variables :
double *xData, *yData;
int numberOfPoints;
float size;
float width;
int style;
NSColor *cocoaColor;

The style is one of four kind of symbols :
PHCrossx, PHCrossplus, PHCircle, PHDiamond

and is set with :
-(void)setStyle:(int)newStyle;

No need to explain what size and width are I guess, and they are set with :
-(void)setSize:(float)newSize;
-(void)setWidth:(float)newWidth;

and the initializer that should be used :

-(id)initWithXData:(double*)xd yData:(double*)yd numberOfPoints:(int)np
xAxis:(PHxAxis*)xaxis yAxis:(PHyAxis*)yaxis;

Changing the number of points :
-(void)setNumberOfPoints:(int)newNumberOfPoints;
