public interface DataProvider

The plotters rely on a DataProvider to get the data to visualize. It provides the data as a DataArray with the getDataArray(int), where the index can be used, if a NodeModel has two inports and both data should be visualized. Then the index provides means to determine which DataArray should be returned.

Method Detail

getDataArray

DataArray getDataArray(int index)

Provides the data that should be visualized. The index can be used, if a NodeModel has two inports and both data should be visualized. Then the index provides means to determine which DataArray should be returned.

Parameters:

index - if the data of more than one data table should be visualized.

Returns:

the data as a data array.
