Method Detail

Image_Graph_Dataset_Trivial (Constructor) [line 73]

Image_Graph_Dataset_Trivial &Image_Graph_Dataset_Trivial(
[array
$dataArray = false])

Image_Graph_Dataset_Trivial [Constructor]

Pass an associated array ($data[$x] = $y) to the constructor for easy data addition. Alternatively (if multiple entries with same x value is required) pass an array with (x, y) values: $data[$id] = array('x' => $x, 'y' => $y);

NB! If passing the 1st type array at this point, the x-values will also be used for ID tags, i.e. when using Image_Graph_Fill_Array. In the 2nd type the key/index of the "outermost" array will be the id tag (i.e. $id in the example)

Parameters:

array $dataArray — An associated array with values to the dataset

addPoint [line 98]

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

Add a point to the dataset

Overridden in child classes as:

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

Overrides Image_Graph_Dataset::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

count [line 184]

int count(
)

The number of values in the dataset

Return: The number of values in the dataset

Overrides Image_Graph_Dataset::count() (The number of values in the dataset)

first [line 112]

array first(
)

The first point

Return: The last point

Overrides Image_Graph_Dataset::first() (The first point)

[ Top ]

last [line 123]

array last(
)

The last point

Return: The first point

Overrides Image_Graph_Dataset::last() (The last point)
