Class ChartDataSummary

public class ChartDataSummary

extends java.lang.Object

Summary represents summary data gathered over a set of number valued channels. A summary contains the following information:

• channels[] - the value channels that ones summary was gathered from
• cumulative[] - cumulativeness for each channel in the set
• hidden[] - visibility for each channel in the set
• sequences - number on channel sequences
• longestSequence - number on channels in the longest sequence
• minValue - cumulative minimum value over the channels in the set
• maxValue - cumulative maximum value over the channels in the set

Consequtive cumulative channels form channel sequences in which individual channel values are added. The first channel and each non-cumulative begin a new channel sequence. The sequences parameter measures the number of these sequences, while longestSequence measures the number of channels in the longest sequence.

The channel order is based on the order in which they appear in the index array that defines the channel set. The channel order may therefore be arranged at will, and a channel may even be used more than once.

Method Detail

createAdditionalValues

public java.util.Map createAdditionalValues()

Creates a map suitable for tuple data additional values. The additional values mechanism allows external values to be seamlessly bound to tuple data element access operations.

The returned map will be a new Map object with the following key-value pairs:

• ChartData.MINVALUE - summary minimum value
• ChartData.MAXVALUE - summary maximum value
