Datasets

The datasets options are managing the set options which will affect the datasets management.

The datasets configuration is passed using the Datasets object in the chart options and mapped to TypedDataset.

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

// sets and gets showLine option to line datasets 
chart.getOptions().getDatasets().get(ChartType.LINE).setShowLine(true);

boolean showLine = chart.getOptions().getDatasets().get(ChartType.LINE).isShowLine();

The following are the attributes that you can set:

Name	Type	Description
animation	Animation	See animation configuration section for more details.
animations	Animations	See animation configuration section for more details.
barPercentage	double	Percent (0-1) of the available width each bar should be within the category width. 1.0 will take the whole category width and put the bars right next to each other.
categoryPercentage	double	Percent (0-1) of the available width each category should be within the sample width.
barThickness	int	Manually set width of each bar in pixels. If set to DefaultDatasets.FLEX_BAR_THICKNESS, it computes "optimal" sample widths that globally arrange bars side by side. If not set (default), bars are equally sized based on the smallest interval.
grouped	boolean	Should the bars be grouped on index axis. When true, all the datasets at same index value will be placed next to each other centering on that index value. When false, each bar is placed on its actual index-axis value.
maxBarThickness	int	Set this to ensure that bars are not sized thicker than this.
minBarLength	int	Set this to ensure that bars have a minimum length in pixels.
showLine	boolean	If true, the line is drawn for dataset.
transitions	Transitions	See animation configuration section for more details.
