Method Details

data

public static BarData data()

Static factory, constructs an Data implementation appropriate for a BarChart.

Returns:

a new BarData instance

options

public static BarOptions options()

Static factory, constructs an Options implementation appropriate for a BarChart.

Returns:

a new BarOptions instance

getType

public String getType()

Returns:

type of this Chart implementation for proper drawing in JavaScript.

isDrawable

public boolean isDrawable()

Optional check to determine whether the current state of this Chart implementation instance will generate a drawable JSON string.

Implementations provide a best-effort evaluation, and can not guarantee that the serialized chart will be rendered correctly.

A BarChart is drawable if:

• at least one dataset has at least one data point
• an xAxis scale exists with the id of the xAxisID set on a dataset, if such an id set
• a yAxis scale exists with the id of the yAxisID set on a dataset, if such an id is set
• there is at least one label in the BarData

Returns:

true if this BarChart is drawable in its current state
