Interface jclass.chart.Chartable

public interface Chartable
Interface used to represent a graphable object. By implementing this interface, any arbitrary object can be provided as a data source for ChartDataView. The Chartable interface does not allow for data modification.

Variable Index

o ARRAY
Enum value indicating that the source data is interpreted as array-style data.
o GENERAL
Enum value indicating that the source data is interpreted as general-style data.

Method Index

o getDataInterpretation()
o getDataItem(int, int)
Retrieves a data item from the data source.
o getName()
Gets the value of the Name property.
o getNumRows()
Gets the NumRows property of the data source, which specifies the number of rows of data available.
o getPointLabels()
Gets the value of the PointLabels property.
o getRow(int)
Retrieves an entire row of data items.
o getSeriesLabel(int)
Gets the value of the SeriesLabel property.
o getSeriesName(int)
Gets the value of the SeriesName property.

Variables

o ARRAY 
  public final static int ARRAY
Enum value indicating that the source data is interpreted as array-style data. The first array or row of data encountered specifies the x values for all data series. Every row after the first row specifies the y values for a single data series.

o GENERAL 
  public final static int GENERAL
Enum value indicating that the source data is interpreted as general-style data. For general data, the rows in the data source are assumed to be sent in groups of two; the first row in a group specifies the x values, and the second row specifies the y values.

Methods

o getDataInterpretation 
  public abstract int getDataInterpretation()
o getDataItem 
  public abstract Object getDataItem(int row,
                                     int column)
Retrieves a data item from the data source.

Parameters:
row - row index
column - column index
Returns:
object-derived data item
o getRow 
  public abstract Vector getRow(int row)
Retrieves an entire row of data items.

Parameters:
row - row index
Returns:
array of object-derived data items
o getNumRows 
  public abstract int getNumRows()
Gets the NumRows property of the data source, which specifies the number of rows of data available.

Returns:
number of available rows
o getPointLabels 
  public abstract String[] getPointLabels()
Gets the value of the PointLabels property. The PointLabels property is an indexed property that contains a list of point labels provided by the data source.

Returns:
array of point labels
o getSeriesName 
  public abstract String getSeriesName(int row)
Gets the value of the SeriesName property. The SeriesName property is a string associated with a row in a data source. It is used by ChartDataView as the name for a data series.

Parameters:
row - index of the row for which the name is returned
Returns:
row/series name
o getSeriesLabel 
  public abstract String getSeriesLabel(int row)
Gets the value of the SeriesLabel property. The SeriesLabel property defines the label that is associated with a data series. The SeriesLabel can be unparsed JCString text, whereas SeriesName is a name used for retrieving data series.

Parameters:
row - index of the row for which the label is returned
Returns:
row/series label
o getName 
  public abstract String getName()
Gets the value of the Name property. The Name property defines the name of the data object
