    Specified by:
    
    createSurface in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:

    profile - configuration object defining plot style
    
    aspect - configuration object defining plot viewpoint
    
    Returns:
    
    new plot surface
  - getProfileKeys
```
public ConfigKey<?>[] getProfileKeys()
```
    Description copied from interface: SurfaceFactory
    
    Returns the configuration keys used to configure profile for this surface factory. The returned keys are used in the map supplied to the createProfile method.
    
    Specified by:
    
    getProfileKeys in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Returns:
    
    profile configuration keys
  - createProfile
```
public TimeSurfaceFactory.Profile createProfile(ConfigMap config)
```
    Description copied from interface: SurfaceFactory
    
    Creates a profile that can be used when creating a plot surface. The keys that are significant in the supplied config map are those returned by getProfileKeys. The return value can be used as input to createSurface and other methods in this class.
    
    Specified by:
    
    createProfile in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:
    
    config - map of profile configuration items
    
    Returns:
    
    factory-specific plot surface profile
  - getAspectKeys
```
public ConfigKey<?>[] getAspectKeys()
```
    Description copied from interface: SurfaceFactory
    
    Returns the configuration keys that may be used to configure aspect for this surface factory. The returned keys are used in the map supplied to the useRanges and createAspect methods.
    
    Specified by:
    
    getAspectKeys in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Returns:
    
    aspect configuration keys
  - useRanges
```
public boolean useRanges(TimeSurfaceFactory.Profile profile,
                         ConfigMap config)
```
    Description copied from interface: SurfaceFactory
    
    Indicates whether ranges should be provided to generate an aspect. If true, it is beneficial to pass the result of readRanges to createAspect alongside the arguments of this method. If false, any such ranges will be ignored.
    
    Specified by:
    
    useRanges in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:
    
    profile - surface configuration profile
    
    config - configuration map that may contain keys from getAspectKeys
    
    Returns:
    
    true iff calculated ranges will be of use
  - createAspect
```
public TimeAspect createAspect(TimeSurfaceFactory.Profile profile,
                               ConfigMap config,
                               Range[] ranges)
```
    Description copied from interface: SurfaceFactory
    
    Creates an aspect from configuration information. The ranges argument will be used only if useRanges returns true. It is legal to give the ranges argument as null in any case. In all cases, the returned value must be non-null and usable by createSurface.
    
    Specified by:
    
    createAspect in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:
    
    profile - surface configuration profile
    
    config - configuration map that may contain keys from getAspectKeys
    
    ranges - range data filled in from layers, or null
    
    Returns:
    
    new aspect
  - getAspectConfig
```
public ConfigMap getAspectConfig(Surface surf)
```
    Description copied from interface: SurfaceFactory
    
    Returns a ConfigMap that corresponds to the configuration of the given surface, which must have been created by this factory. The intention is that supplying the returned config items to this object's createAspect method with the right profile should come up with approximately the same surface, preferably without reference to any supplied ranges.
    The returned config items should be optimised for presentation to the user, so that for instance decimal values are reported to a reasonable level of precision. Because of this, and perhaps for other reasons related to implementation, a surface resulting from feeding the returned config back to this factory may not be identical to the supplied surface, so round-tripping is not guaranteed to be exact.
    
    Specified by:
    
    getAspectConfig in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:
    
    surf - plot surface; if it was not created by this factory, behaviour is undefined
    
    Returns:
    
    config map populated with items that should approximately reproduce the supplied surface
  - readRanges
```
public Range[] readRanges(TimeSurfaceFactory.Profile profile,
                          PlotLayer[] layers,
                          DataStore dataStore)
```
    Description copied from interface: SurfaceFactory
    
    Provides the ranges that may be passed to createAspect. There is only any point calling this if useRanges returns true.
    
    Specified by:
    
    readRanges in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:
    
    profile - surface configuration profile
    
    layers - plot layers to be plotted
    
    dataStore - contains actual data
    
    Returns:
    
    data ranges covered by the given layers filled in from data
  - getNavigatorKeys
```
public ConfigKey<?>[] getNavigatorKeys()
```
    Description copied from interface: SurfaceFactory
    
    Returns the configuration keys that may be used to configure a navigator for use with this surface factory. The returned keys are used in the map supplied to the SurfaceFactory.createNavigator(uk.ac.starlink.ttools.plot2.config.ConfigMap) method.
    
    Specified by:
    
    getNavigatorKeys in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Returns:
    
    navigator configuration keys
  - createNavigator
```
public Navigator<TimeAspect> createNavigator(ConfigMap navConfig)
```
    Description copied from interface: SurfaceFactory
    
    Creates a navigator from configuration information. The returned value will be non-null.
    
    Specified by:
    
    createNavigator in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Parameters:
    
    navConfig - configuration map that may contain keys from getNavigatorKeys
    
    Returns:
    
    navigator for use with surfaces produced by this factory
  - getPlotMetric
```
public PlotMetric getPlotMetric()
```
    Description copied from interface: SurfaceFactory
    
    Returns an object that can assess distances between graphic positions on the plot surface. If no such metric exists, null may be returned.
    
    Specified by:
    
    getPlotMetric in interface SurfaceFactory<TimeSurfaceFactory.Profile,TimeAspect>
    
    Returns:
    
    plot metric, or null
