Package uk.ac.ed.epcc.webapp.charts

Package of helper classes for the generation of charts in a web-application The main classes are independent of the graphing package used.

See: Description

Interface Summary

Interface	Description
BarTimeChartData<S extends PeriodSetPlot>
ChartData<P extends Plot>	Interface for objects that represent the actual Chart graphic Objects implementing this interface are intended to be the graphic-library internal implementation of chart objects.
PeriodChartData<P extends PeriodPlot>
PeriodPlot	A SetPlot where each data value in a set corresponds to a period of time.
PeriodSequencePlot	Each set of data consists of a sequence of time periods.
PeriodSetPlot
PieChartData<P extends SingleValueSetPlot>	A ChartData that represents a PieChart
PieTimeChartData<P extends PeriodSetPlot>
Plot	A class representing plot data
ScatterPeriodChartData<P extends ScatterPeriodPlot>
ScatterPeriodPlot
SetPlot	Plot represents the Data in the chart being created.
SingleValueSetPlot	This is a Plot where each member of the set only contain a single value.
TimeChartData<P extends PeriodSequencePlot>	A ChartData that represents a TimeChart

Class Summary

Class	Description
AbstractPeriodSetPlot
AbstractSingleValueSetPlot	This is a abstract superclass for SingleValueSetPlot that implements the methods from SetPlot via the additional methods in SingleValueSetPlot.
BarTimeChart<S extends PeriodSetPlot>	BarTimeChart This is the bar chart equivalent of a TimeChart and is functionally equivalent to PieTimeChart.
Chart<P extends Plot>	Chart is a base class for chart generation.
GenericSetPlot	generic version of plot for use where the underlying data-model of the graphics class is radically different
GenericSplitSetPlot	generic version of plot for use where the underlying datamodel of the graphics class is radically different
GraphService	An AppContextService that selects the desired chart implementation classes
ListSorter	ListSorter sorts an array of indecies according to the values in an array
PeriodChart<P extends PeriodPlot>	PeriodChart is a Chart where the data represents a plot over some period of time.
PieChart	A basic piechart where the data comes from a Table or Map
PieTimeChart<P extends PeriodSetPlot>	PieTimeChart This is the PieChart equivalent of a TimeChart It plots the sum of quantities over a period and uses the same mapping classes the intention is that you can use this to generate piecharts and timecharts interchangably.
ScatterPeriodChart<P extends ScatterPeriodPlot>	A ScatterPeriodChart is a scatter plot where each point is generated by a different time period.
SetPeriodChart<P extends PeriodPlot>	PeriodCharts that represent a set of values such as a pie-chart of bar-chart.
SplitSetPlot	A SplitSetPlot is a PeriodSequencePlot where the data is split over a series of time periods The time periods are divided into Major/Minor sub-divisions called Catagories and Items.
TimeChart<P extends PeriodSequencePlot>	A helper class used to make graphs Basic constructors define the time range, We then use call methods that add additional plots these return the PeriodSequencePlot so we can add data with the addData methods.

Exception Summary

Exception	Description
InvalidTransformException	Exception thrown when a problem occurs mapping data to a plot

Package uk.ac.ed.epcc.webapp.charts Description

Package of helper classes for the generation of charts in a web-application The main classes are independent of the graphing package used. Each chart class contains a class implementing the ChartData interface which contains the package specific code.
