getPlotterName
public java.lang.String getPlotterName()
Description copied from interface:Plotter
Returns the name of this plotter for use in user interface.- Specified by:
getPlotterName
in interfacePlotter<GridPlotter.GridStyle>
- Returns:
- user-directed plotter name
-
getPlotterIcon
public javax.swing.Icon getPlotterIcon()
Description copied from interface:Plotter
Returns an icon for this plotter for use in user interface.- Specified by:
getPlotterIcon
in interfacePlotter<GridPlotter.GridStyle>
- Returns:
- plotter icon
-
getCoordGroup
public CoordGroup getCoordGroup()
Description copied from interface:Plotter
Returns an object describing which data coordinates are used for this plotter and how they are arranged in supplied DataSpec objects.- Specified by:
getCoordGroup
in interfacePlotter<GridPlotter.GridStyle>
- Returns:
- coordinate group
-
hasReports
public boolean hasReports()
Description copied from interface:Plotter
Indicates whether the drawings produced by this plotter will return general interest report information to upstream plotting code.- Specified by:
hasReports
in interfacePlotter<GridPlotter.GridStyle>
- Returns:
- true if the plot report may return interesting information
- See Also:
Drawing.getReport(java.lang.Object)
-
getPlotterDescription
public java.lang.String getPlotterDescription()
Description copied from interface:Plotter
Returns an XML description of this plotter.Note: really this should appear at the LayerType level.
- Specified by:
getPlotterDescription
in interfacePlotter<GridPlotter.GridStyle>
- Returns:
- one or more <p> elements
-
getStyleKeys
public ConfigKey<?>[] getStyleKeys()
Description copied from interface:Plotter
Returns the configuration keys used to configure style for this plotter. The keys in the return value are used in the map supplied to thePlotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap)
method.- Specified by:
getStyleKeys
in interfacePlotter<GridPlotter.GridStyle>
- Returns:
- keys used when creating a style for this plotter.
-
createStyle
public GridPlotter.GridStyle createStyle(ConfigMap config)
Description copied from interface:Plotter
Creates a style that can be used when creating a plot layer. The keys that are significant in the supplied config map are those returned byPlotter.getStyleKeys()
. The return value can be used as input toPlotter.createLayer(uk.ac.starlink.ttools.plot2.DataGeom, uk.ac.starlink.ttools.plot2.data.DataSpec, S)
.- Specified by:
createStyle
in interfacePlotter<GridPlotter.GridStyle>
- Parameters:
config
- map of style configuration items- Returns:
- plotter-specific plot style
-
getRangeStyleKey
public java.lang.Object getRangeStyleKey(GridPlotter.GridStyle style)
Description copied from interface:Plotter
Returns an opaque object characterising the region of the plot surface covered when using a given plotter style. If this object changes between layers produced by this plotter, it provides a hint that it may be necessary to redetermine the axis ranges (usingextendCoordinateRanges
).In many cases, such as scatter-plot-like plotters, the range is determined only by the coordinate data (managed by
DataSpec
inputs) so a null value may be returned. This method is chiefly required by histogram-like plotters for which the region on the plot surface is not the union of the input positions.- Specified by:
getRangeStyleKey
in interfacePlotter<GridPlotter.GridStyle>
- Parameters:
style
- plot style to assess- Returns:
- opaque object with equality semantics, or null if axis range is not a function of style
-
createLayer
public PlotLayer createLayer(DataGeom geom, DataSpec dataSpec, GridPlotter.GridStyle style)
Description copied from interface:Plotter
Creates a PlotLayer based on the given geometry, data and style.The
style
parameter is the result of a call toPlotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap)
.The
dataSpec
parameter must contain the coordinates defined by this plotter's CoordGroup.The
pointDataGeom
parameter is only used ifgetCoordGroup()
.getPositionCount
returns a non-zero value, otherwise the plot does not have point positions.It is legal to supply null for any of the parameters; if insufficient data is supplied to generate a plot, then the method should return null.
Creating a layer should be cheap; layers may be created and not used.
- Specified by:
createLayer
in interfacePlotter<GridPlotter.GridStyle>
- Parameters:
geom
- indicates base position coordinates and their mapping to points in the data space; if non-null, the data geom'sDataGeom.hasPosition()
method will return truedataSpec
- specifies the data required for the plotstyle
- data style as obtained fromcreateStyle
- Returns:
- new plot layer, or null if no drawing will take place
