Member Function Documentation

add_series()

core\chart_base::add_series ( chart_series  $serie )

inherited

Add a series to the chart.

Parameters

chart_series

$serie

The serie.

get_labels()

core\chart_base::get_labels ( )

inherited

Get the labels of the X axis.

Return values

string[]

get_series()

core\chart_base::get_series ( )

inherited

Get the series.

Return values

chart_series[]

get_smooth()

core\chart_line::get_smooth

(

)

Get whether a lines should be smooth or not.

Return values

bool

get_title()

core\chart_base::get_title ( )

inherited

Get the title.

Return values

string

get_type()

core\chart_base::get_type ( )

inherited

Get the chart type.

Return values

string

get_xaxes()

core\chart_base::get_xaxes ( )

inherited

Get the X axes.

Return values

chart_axis[]

get_xaxis()

core\chart_base::get_xaxis (   $index = 0,   $createifnotexists = false  )

inherited

Get an X axis.

Parameters

int	$index	The index of the axis.
bool	$createifnotexists	When true, create an instance of the axis if none exist at this index yet.

Return values

chart_axis

get_yaxes()

core\chart_base::get_yaxes ( )

inherited

Get the Y axes.

Return values

chart_axis[]

get_yaxis()

core\chart_base::get_yaxis (   $index = 0,   $createifnotexists = false  )

inherited

Get a Y axis.

Parameters

int	$index	The index of the axis.
bool	$createifnotexists	When true, create an instance of the axis if none exist at this index yet.

Return values

chart_axis

jsonSerialize()

core\chart_line::jsonSerialize

(

)

Add the smooth to the parent and return the serialized data.

Return values

array

Reimplemented from core\chart_base.

set_defaults()

core\chart_base::set_defaults ( )

protectedinherited

Set the defaults for this chart type.

Child classes can extend this to set default values on instantiation.

In general the constructor could be used, but this method is here to emphasize and self-document the default values set by the chart type.

Return values

void

Reimplemented in core\chart_bar.

set_labels()

core\chart_base::set_labels ( array  $labels )

inherited

Set the chart labels.

Parameters

string[]

$labels

The labels.

set_smooth()

core\chart_line::set_smooth

(

$smooth

)

Set Whether the line should be smooth or not.

Parameters

bool

$smooth

True if the line chart should be smooth, false otherwise.

set_title()

core\chart_base::set_title (   $title )

inherited

Set the title.

Parameters

string

$title

The title.

set_xaxis()

core\chart_base::set_xaxis ( chart_axis  $axis,   $index = 0  )

inherited

Set an X axis.

Note that this will override any predefined axis without warning.

Parameters

chart_axis	$axis	The axis.
int	$index	The index of the axis.

set_yaxis()

core\chart_base::set_yaxis ( chart_axis  $axis,   $index = 0  )

inherited

Set an Y axis.

Note that this will override any predefined axis without warning.

Parameters

chart_axis	$axis	The axis.
int	$index	The index of the axis.

validate_axis()

core\chart_base::validate_axis (   $xy, chart_axis  $axis,   $index = 0  )

protectedinherited

Validate an axis.

We validate this from PHP because not doing it here could result in errors being hard to trace down. For instance, if we were to add axis at keys without another axis preceding, we would effectively contain the axes in an associative array rather than a simple array, and that would have consequences on serialisation.

Parameters

string	$xy	Accepts x or y.
chart_axis	$axis	The axis to validate.
index	$index	The index of the axis.
