Interface PeriodSequencePlot

All Superinterfaces:

PeriodPlot, Plot, SetPlot

All Known Implementing Classes:

GenericSplitSetPlot, SplitSetPlot, TimeChartDataSet

public interface PeriodSequencePlot
extends PeriodPlot

Each set of data consists of a sequence of time periods. The time periods do not have to be of equal length. The same set of time periods apply to each set of data.

Method Summary

Modifier and Type	Method and Description
void	datasetScale(double scale, PeriodSequencePlot norm) rescale a dataset by constant divided by the value in a different dataset The normalisation dataset is assumed to have a single Set belong to the same class as this object and use the same set of time periods.
void	doConvertToStacked() convert to stacked (each set stacks on top of each other).
java.util.Iterator<TimePeriod>	getSubPeriods() get an Iterator over the time periods in the sequence.
void	rateScale(double scale) re-scale all data values to by factor divided by the number of milliseconds in the period.
void	scaleCopy(double scale, int src, int dest) copy the contents of one set to another scaling the values.
void	scaleCumulative(double scale, double[] initial) Convert the data-set to a cumulative graph.

Method Detail

rateScale

void rateScale(double scale)

re-scale all data values to by factor divided by the number of milliseconds in the period. This generates a rate value that will be correct even if the periods are not equal lengths.

Parameters:

scale -

scaleCumulative

void scaleCumulative(double scale,
                     double[] initial)

Convert the data-set to a cumulative graph. each value is replaced by the sum of previous values in the set plus the initial value for that set then scaled by the scale value. At the end of this operation the initial vector will have been incremented by the accumulated (un-scaled) values from each set in the original state.

Parameters:

scale -

initial -

scaleCopy

void scaleCopy(double scale,
               int src,
               int dest)

copy the contents of one set to another scaling the values.

Parameters:

scale -

src -

dest -

getSubPeriods

java.util.Iterator<TimePeriod> getSubPeriods()

get an Iterator over the time periods in the sequence.

Returns:

doConvertToStacked

void doConvertToStacked()

convert to stacked (each set stacks on top of each other).

datasetScale

void datasetScale(double scale,
                  PeriodSequencePlot norm)

rescale a dataset by constant divided by the value in a different dataset The normalisation dataset is assumed to have a single Set belong to the same class as this object and use the same set of time periods.

Parameters:

ds -

scale -

norm -
