Class ProxyPlot

java.lang.Object

org.eclipse.eavp.viz.service.AbstractPlot

org.eclipse.eavp.viz.service.ProxyPlot

All Implemented Interfaces:

IPlot, IVizCanvas

Direct Known Subclasses:

CSVProxyPlot

public abstract class ProxyPlot
extends AbstractPlot

This class provides a proxy plot that points to a source IPlot implementation. This is used to share plot data between multiple drawings of a source plot.

This proxy plot will create its own copies of the dependent series in the source plot. These copies will point to the data in the source plot's series, while each copy will be customizable. This applies to the methods below:

• getCategories() - uses a map loaded from the source IPlot
• getDependentSeries(String) - uses ProxySeries that point at the source plot's ISeries

The following methods are re-directed to the source plot.

• getDataSource()
• getNumberOfAxes()

On the other hand, all remaining methods will use data stored in this proxy as they rely in the AbstractPlot implementation.

Constructor Detail

ProxyPlot

public ProxyPlot()

The default constructor.

Method Detail

getCategories

public java.util.List<java.lang.String> getCategories()

Description copied from interface: IPlot

Gets all of the categories currently associated with this plot.

Specified by:

getCategories in interface IPlot

Overrides:

getCategories in class AbstractPlot

Returns:

The categories for this plot.

getDataSource

public java.net.URI getDataSource()

Description copied from interface: IVizCanvas

This operation returns the data source that is plotted/drawn by this IPlot.

Specified by:

getDataSource in interface IVizCanvas

Overrides:

getDataSource in class AbstractPlot

Returns:

The data source

getDependentSeries

public java.util.List<ISeries> getDependentSeries(java.lang.String category)

Description copied from interface: IPlot

Gets all of the dependent series specified for this IPlot, as a list, for the specified category. If the category is null, will return the default category.

Specified by:

getDependentSeries in interface IPlot

Overrides:

getDependentSeries in class AbstractPlot

Returns:

List all of the dependent series to be plotted.

getNumberOfAxes

public int getNumberOfAxes()

Description copied from interface: IVizCanvas

This operation returns the number of axes of the plot.

Specified by:

getNumberOfAxes in interface IVizCanvas

Overrides:

getNumberOfAxes in class AbstractPlot

Returns:

The number of axes or zero if the plot has not been drawn

setSource

public void setSource(IPlot source)

Sets the source IPlot on which this plot is based. This method synchronizes this plot's dependent series with those of the original plot by creating a ProxySeries to those of the source plot.

Parameters:

source - The source plot. If null, the source will be unset and all dependent series will be cleared.
