public class CategoryData
extends AbstractData<String>
implements CategoryDataProvider

A list-based data provider for category data. Category data is typically non-numeric kind of (string) data that can be used in many charts like in the X-axis of a BarChart. It is also used when data/item labels are required, for example: PieChart.

Constructor Details

CategoryData

public CategoryData(String... data)

Constructor.

Parameters:

data - Initial data to add

Method Details

getMin

public String getMin()

Description copied from interface: AbstractDataProvider

Get the minimum value from this data. This is used by certain components such as VisualMap to automatically find out the minimum value of a value-based chart.

The default implementation tries to use the Comparator returned by the AbstractDataProvider.getComparator() method to determine this value. If no Comparator is available, null will be returned.

Specified by:

getMin in interface AbstractDataProvider<String>

Returns:

Minimum value of the data.

getMax

public String getMax()

Description copied from interface: AbstractDataProvider

Get the maximum value from this data. This is used by certain components such as VisualMap to automatically find out the minimum value of a value-based chart.

The default implementation tries to use the Comparator returned by the AbstractDataProvider.getComparator() method to determine this value. If no Comparator is available, null will be returned.

Specified by:

getMax in interface AbstractDataProvider<String>

Returns:

Minimum value of the data.
