Defaults charts options

Version: 5.3

Commons charts options

To change the global options, Charba is providing the method getGlobal in the Defaults class. These options will be applied to all charts, whatever type of chart.

With above method you can get all global configurations of Chart.JS and you have got all set and get methods to change or retrieve the global configuration items.

// --------------------------------------
// GLOBAL, for all charts (whatever type)
// --------------------------------------
Defaults.get().getGlobal().setResponsive(false);
Defaults.get().getGlobal().setMaintainAspectRatio(true);

double circumference = Defaults.get().getGlobal().getCircumference();
CLocale locale = Defaults.get().getGlobal().getLocale();

The following are the attributes that you can set:

Name	Type	Default	Description
aspectRatio	double	2	Canvas aspect ratio (i.e. width / height, a value of 1 representing a square canvas).
backgroundColor	String - IsColor	rgba(0,0,0,0.1) -	The default background color to use in the chart.
borderColor	String - IsColor	rgba(0,0,0,0.1) -	The default border color to use in the chart.
circumference	double	360	The sweep to allow arcs to cover.
color	String - IsColor	#666 -	The default font color to use in the chart.
cutoutPercentage	String	`null`	The percentage of the chart that is cut out of the middle. It's a string, ending with '%', as percentage of the chart radius. See pie and doughnut chart configuration for defaults.
cutout	double	`Undefined.DOUBLE`	The portion of the chart that is cut out of the middle, in pixels. See pie and doughnut chart configuration for defaults.
destroyOnDetach	boolean	`true`	`true` if the chart is configured to be destroyed on the detach from element.
devicePixelRatio	double	Window.getDevicePixelRatio()	Default device pixel ratio. By default the chart's canvas will use a 1:1 pixel ratio, unless the physical display has a higher pixel ratio.
drawOnAttach	boolean	`true`	`true` if the chart is configured to be draw on the attach of element
events	Event[]	Event.MOUSEMOVE, Event.MOUSEOUT, Event.CLICK, Event.TOUCHSTART, Event.TOUCHMOVE	The events option defines the browser events that the chart should listen to.
indexAxis	IndexAxis	IndexAxis.X	The base axis for the BAR dataset. Use 'y' for horizontal bar.

maintainAspectRatio	boolean	`true`	Maintain the original canvas aspect ratio (width / height) when resizing.
radiusPercentage	String	`100%`	the outer radius of the chart. It's a string, ending with '%', as percentage of the maximum radius.
radius	double	`Undefined.DOUBLE`	The outer radius of the chart, in pixels.
resizeDelay	int	0	Delay the resize update by give amount of milliseconds. This can ease the resize process by debouncing update of the elements.
responsive	boolean	`true`	Resizes the chart canvas when its container does.
responsiveAnimationDuration	int	0	Duration in milliseconds it takes to animate to new size after a resize event.
rotation	double	0	The starting angle to draw arcs from.

spanGaps	boolean - double	`false`	If `true`, lines will be drawn between points with no or null data. If `false`, points with `NaN` data will create a break in the line. Can also be a number specifying the maximum gap length to span. The unit of the value depends on the scale used.

The options element is the root node of several other elements you can set to configure the charts as you need.

Font

There are special global settings that can change all fonts on all charts. The global font settings only apply when more specific options are not included in the configuration.

Animations

Animations options configures which element properties are animated and how.

The animations element is a container of configurations which can be stored and retrieved by a key.

To get, change and apply own properties, you can invoke the set and get methods, as following:

// --------------------------------------
// GLOBAL, for all charts (whatever type)
// --------------------------------------
AnimationCollectionKey key = AnimationCollectionKey.create("myKey", AnimationType.NUMBER);
// creates and gets an animation configuration item by my key

padding	Padding	`0` on all sides	To set specific padding for specific sides.

See padding documentation for more details.

Decimation

The decimation element can be used with line charts to automatically decimate data at the start of the chart life cycle.

Before enabling it, review the requirements to ensure that it will work with the chart you want to create.

The decimation configuration is nested in the global configuration as following:

// --------------------------------------
// GLOBAL, for all charts (whatever type)
// --------------------------------------
Defaults.get().getGlobal().getDecimation().setSamples(1000);

double samples = Defaults.get().getGlobal().getDecimation().getSamples();

The following are the attributes that you can set:

Name	Type	Default	Description
enabled	boolean	`false`	If `true`, the data decimation is enabled.
algorithm	DecimationAlgorithm	DecimationAlgorithm.MIN_MAX	Decimation algorithm to use.
samples	double	Undefined.DOUBLE	If the `DecimationAlgorithm.LTTB` is used, this is the number of samples in the output dataset. Defaults to the canvas width to pick 1 sample per pixel.
threshold	double	Undefined.DOUBLE	If the number of samples in the current axis range is above this value, the decimation will be triggered. Defaults to 4 times the canvas width. The number of point after decimation can be higher than the `threshold` value.

Algorithms

The available decimation algorithms to use for data are the following:

DecimationAlgorithm.MIN_MAX: it will preserve peaks in your data but could require up to 4 points for each pixel. This type of decimation would work well for a very noisy signal where you need to see data peaks.
DecimationAlgorithm.LTTB (Largest Triangle Three Bucket): it reduces the number of data points significantly. This is most useful for showing trends in data using only a few data points.

Requirements

To use the decimation, the following requirements must be met:

The dataset must have an IndexAxis of IndexAxis.X.
The dataset must be a line.
The X axis for the dataset must be either a linear or time axis.

Filler

Filler element configures the engine which is in charge to manage the filling of the datasets, by the property fill. See here how filling a dataset.

The filler configuration is nested in the global configuration as following:

// --------------------------------------
// GLOBAL, for all charts (whatever type)
// --------------------------------------
Defaults.get().getGlobal().getFiller().setPropagate(false);

boolean propagate = Defaults.get().getGlobal().getFiller().isPropagate();

The following are the attributes that you can set:

Name	Type	Default	Description
propagate	boolean	`true`	If `true`, the fill area will be recursively extended to the visible target defined by the fill value of hidden data set targets.
drawTime	DrawTime	DrawTime.BEFORE_DATASET_DRAW	Filler draw time.
