Class: Image_Graph_Dataset

Child classes:

Image_Graph_Dataset_Trivial: Trivial data set, simply add points (x, y) 1 by 1

Image_Graph_Dataset_VectorFunction: Vector Function data set, points are generated by calling 2 external functions, x = sin(t) and y = cos(t)

Image_Graph_Dataset_Function: Function data set, points are generated by calling an external function.

addPoint [line 114]

void addPoint(
int
$x, [int
$y = false], [var
$ID = false])

Add a point to the dataset

Overridden in child classes as:

Image_Graph_Dataset_Trivial::addPoint(): Add a point to the dataset

Image_Graph_Dataset_Sequential::addPoint(): Add a point to the dataset

Image_Graph_Dataset_VectorFunction::addPoint(): Add a point to the dataset

Image_Graph_Dataset_Function::addPoint(): Add a point to the dataset.

Parameters:

int	`$x`	—	The X value to add
int	`$y`	—	The Y value to add, can be omited
var	`$ID`	—	The ID of the point
