All Implemented Interfaces:

Serializable

public class JCDefaultDataInterpreter

extends JCDataInterpreter

implements Serializable

Implements a interpreter for the default chart data format. Relies on input from some reader to populate the specified BaseDataSource class.

Format Information

Array Format Examples: In array format, there is one set of x-axis data, multiple sets of y-axis data. The data may or may not be transposed, for example the two following data files are equivalent:

 ARRAY 2 4  # 2 series (+x-data) w. 4 points each
 1 2 3 4    # x-data
 1 2 3 4    # y1
 1 4 9 16   # y2
 

and

 ARRAY 2 4 T
 1 1 1
 2 2 4
 3 3 9
 4 4 16
 

Or, with names and point labels,

 ARRAY 'My Chart' 2 4
                 'Point Label 1' 'Point Label 2' 'Point Label 3' 'Point Label 4'
 'X Axis Data'    1               2               3               4
 'Y Axis #1 Data' 1               2               3               4
 'Y Axis #2 Data' 1               4               9               16
 

or

 ARRAY 'MyChart' 2 4 T
                'X Data' 'Y Data' 'Y 2 Data'
 'Point Label 1' 1        1        1
 'Point Label 2' 2        2        4
 'Point Label 3' 3        3        9
 'Point Label 4' 4        4        16
 

General format examples: In general format, there are multiple x series.

 # 3 lines, max 5 points each
 GENERAL 3 5
 # line 1, 3 points
 3
 1 3 5    # x-values
 5 14 24  # y-values
 # line 2, 5 points
 5
 1 2 3 4 5
 11 15 18 21 22
 # line 3, 2 points
 2
 2 4
 16 15.2
 

or, using the transposed format

 GENERAL 3 5 T
 # line 1, 3 points
 3
 # X  Y
 1   5
 3  14
 5  24
 # line 2, 5 points
 5
 # X  Y
 1   11
 2   15
 3   18
 4   21
 5   22
 # line 3, 2 points
 2
 # X  Y
 2   16
 4   15.2
 

Or, with point labels and series names

 GENERAL 3 5
 LABELS 'Mercury' 'Venus' 'Earth' 'Mars' 'Jupiter'
 'Series 1' 3
 1 3 5
 5 14 24
 'Series 2' 5
 1 2 3 4 5
 11 15 18 21 22
 'Series 3' 2

Constructor Detail

JCDefaultDataInterpreter

public JCDefaultDataInterpreter(com.klg.jclass.chart.data.BaseDataSource bds)

This constructor creates an instance of a data interpreted and associates it with a data source. It does not yet do any interpreting.

Parameters:

bds - the data source to eventually be populated with the interpreted data

JCDefaultDataInterpreter

public JCDefaultDataInterpreter()

Default no-argument constructor.

Method Detail

ctor

protected void ctor(Reader r)
             throws IOException

Parses the specified input stream according to the default chart data format and populates the previously set data source. Called by the other ctor() method, and also used for String input where you can't have an input stream.

Specified by:

ctor in class JCDataInterpreter

Parameters:

r - the Reader object used to read data

Throws:

IOException
