Class Details

[line 51]
A normal axis thats displays labels with a 'interval' of 1.

This is basically a normal axis where the range is the number of labels defined, that is the range is explicitly defined when constructing the axis.

Method Detail

Image_Graph_Axis_Category (Constructor) [line 66]

Image_Graph_Axis_Category Image_Graph_Axis_Category(
[int
$type = IMAGE_GRAPH_AXIS_X])

Image_Graph_Axis_Category [Constructor].

Parameters:

int $type — The type (direction) of the Axis

[ Top ]

forceMaximum [line 143]

void forceMaximum(
double
$maximum, [
$userEnforce = true])

Forces the maximum value of the axis

A maximum cannot be set on a SequentialAxis, it is always the number of labels passed to the constructor.

Overrides Image_Graph_Axis::forceMaximum() (Forces the maximum value of the axis)

Parameters:

double	`$maximum`	—	The maximum value to use on the axis
	`$userEnforce`	—

[ Top ]

forceMinimum [line 131]

void forceMinimum(
double
$minimum, [
$userEnforce = true])

Forces the minimum value of the axis

A minimum cannot be set on a SequentialAxis, it is always 0.

Overrides Image_Graph_Axis::forceMinimum() (Forces the minimum value of the axis)

Parameters:

double	`$minimum`	—	The minumum value to use on the axis
	`$userEnforce`	—

[ Top ]

setLabelInterval [line 154]

void setLabelInterval(
[double
$labelInterval = 'auto'], [
$level = 1])

Sets an interval for where labels are shown on the axis.

The label interval is rounded to nearest integer value

Overrides Image_Graph_Axis::setLabelInterval() (Sets an interval for when labels are shown on the axis.)

Parameters:

double	`$labelInterval`	—	The interval with which labels are shown
	`$level`	—
