Class: chart_base - X-Ref
Chart base class.__construct() X-Ref |
Constructor. Must not take any argument. Most of the time you do not want to extend this, rather extend the method {@link self::set_defaults} to set the defaults on instantiation. |
add_series(chart_series $serie) X-Ref |
Add a series to the chart. param: chart_series $serie The serie. |
jsonSerialize() X-Ref |
Serialize the object. return: array |
get_axis($type, $index, $createifnotexists) X-Ref |
Get an axis. param: string $type Accepts values 'x' or 'y'. param: int $index The index of this axis. param: bool $createifnotexists Whether to create the axis if not found. return: chart_axis |
get_labels() X-Ref |
Get the labels of the X axis. return: string[] |
get_legend_options() X-Ref |
Get an array of options for the chart legend. return: array |
get_series() X-Ref |
Get the series. return: chart_series[] |
get_title() X-Ref |
Get the title. return: string |
get_type() X-Ref |
Get the chart type. return: string |
get_xaxes() X-Ref |
Get the X axes. return: chart_axis[] |
get_xaxis($index = 0, $createifnotexists = false) X-Ref |
Get an X axis. param: int $index The index of the axis. param: bool $createifnotexists When true, create an instance of the axis if none exist at this index yet. return: chart_axis |
get_yaxes() X-Ref |
Get the Y axes. return: chart_axis[] |
get_yaxis($index = 0, $createifnotexists = false) X-Ref |
Get a Y axis. param: int $index The index of the axis. param: bool $createifnotexists When true, create an instance of the axis if none exist at this index yet. return: chart_axis |
set_defaults() X-Ref |
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: void |
set_labels(array $labels) X-Ref |
Set the chart labels. param: string[] $labels The labels. |
set_legend_options(array $legendoptions) X-Ref |
Set options for the chart legend. See https://www.chartjs.org/docs/2.7.0/configuration/legend.html for options. Note: Setting onClick and onHover events is not directly supported through this method. These config options must be set directly within Javascript on the page. param: array $legendoptions Whether or not to display the chart's legend. |
set_title($title) X-Ref |
Set the title. param: string $title The title. |
set_xaxis(chart_axis $axis, $index = 0) X-Ref |
Set an X axis. Note that this will override any predefined axis without warning. param: chart_axis $axis The axis. param: int $index The index of the axis. |
set_yaxis(chart_axis $axis, $index = 0) X-Ref |
Set an Y axis. Note that this will override any predefined axis without warning. param: chart_axis $axis The axis. param: int $index The index of the axis. |
validate_axis($xy, chart_axis $axis, $index = 0) X-Ref |
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. param: string $xy Accepts x or y. param: chart_axis $axis The axis to validate. param: index $index The index of the axis. |
