All Implemented Interfaces:

Series, Serializable
```
public class DataProviderSeries<T>
extends AbstractSeries
```
A series which is based on data from a DataProvider.
You must use setY(SerializableFunction) to define which part of the data bean to use as y values.
Note that even if you use a lazy loading DataProvider, this series will work in an eager fashion and load all the data from the provider at once.

- Constructor Detail
  - DataProviderSeries
```
public DataProviderSeries(DataProvider<T,?> dataProvider)
```
    Creates a new series using data from the given data provider.
    Many chart types such as ChartType.BAR, ChartType.LINE, ChartType.AREA etc use y values to define the data points to show in the chart. For these chart types you should use either DataProviderSeries(DataProvider, SerializableFunction) or setY(SerializableFunction) to define the function (lambda) which extracts the values from the bean in the provider.
    Other chart types such as ChartType.ERRORBAR do not require y values but instead high and low values. Functions for extracting these are set using setHigh(SerializableFunction) and setLow(SerializableFunction) respectively.
    
    Parameters:
    
    dataProvider - the data provider which contains the data
  - DataProviderSeries
```
public DataProviderSeries(DataProvider<T,?> dataProvider,
                          SerializableFunction<T,Object> callBack)
```
    Creates a new series using data from the given data provider and y values.
    
    Parameters:
    
    dataProvider - the data provider which contains the data
    
    callBack - the function which retrieves the y values
- Method Detail
  - setProperty
```
public void setProperty(String propertyName,
                        SerializableFunction<T,Object> callBack)
```
    Sets the function used for retrieving the value for the given property name from the given data provider.
    
    Parameters:
    
    propertyName - the property name
    
    callBack - the function which retrieves the value for the property
  - setX
```
public void setX(SerializableFunction<T,Object> callBack)
```
    Sets the function used for retrieving x values from the bean provided by the data provider.
    How exactly the values are used depends on the used chart type.
