Class ProjectionAxis

org.pepstock.charba.client.geo.ProjectionAxis

public final class ProjectionAxis
extends Axis

A map projection is a way to flatten a globe's surface into a plane in order to make a map.
This requires a systematic transformation of the latitudes and longitudes of locations from the surface of the globe into locations on a plane.
This is the scale which is managing the map projection.

Field Detail

ID

public static final ScaleId ID

Projection axis id.

TYPE

public static final AxisType TYPE

Projection axis type.

Constructor Detail

ProjectionAxis

public ProjectionAxis(IsChart chart)

Builds the object storing the chart instance.

Parameters:

chart - chart instance

Method Detail

getPadding

public Padding getPadding()

Returns the padding applied during auto scaling of the map in pixels, i.e. the chart size is reduce by the padding before fitting the map.

Returns:

the padding applied during auto scaling of the map in pixels

setProjection

public void setProjection(Projection projection)

Sets a map projection which is a way to flatten a globe's surface into a plane in order to make a map.

Parameters:

projection - a map projection which is a way to flatten a globe's surface into a plane in order to make a map

getProjection

public Projection getProjection()

Returns a map projection which is a way to flatten a globe's surface into a plane in order to make a map.

Returns:

a map projection which is a way to flatten a globe's surface into a plane in order to make a map

setProjectionScale

public void setProjectionScale(double projectionScale)

Sets how much the map will be scaled.

Parameters:

projectionScale - how much the map will be scaled

getProjectionScale

public double getProjectionScale()

Returns how much the map will be scaled.

Returns:

how much the map will be scaled

setProjectionOffset

public void setProjectionOffset(double x,
                                double y)

Sets a map projection offset value.

Parameters:

x - x offset where the map has been placed

y - y offset where the map has been placed

getProjectionOffset

public List<Double> getProjectionOffset()

Returns a map projection offset value.

Returns:

a map projection offset value.

setConfiguration

protected final void setConfiguration(T configuration)

Parameters:

configuration - the configuration to set

getConfiguration

protected final T getConfiguration()

Returns the configuration element.

Returns:

the configuration element.

merge

public final void merge(NativeObjectContainer source,
                        String property)

Merge a native object in the this one with a specific property name.
This is used by plugins implementation (native java script ones) when they are not using the standard way to add plugin configuration in the options of chart.

Parameters:

source - native object container to add

property - property name

toJSON

public final String toJSON()

Returns the JSON representation of the object.

Returns:

the JSON representation of the object.

loadNativeObject

public final ChartEnvelop<NativeObject> loadNativeObject(ChartEnvelop<NativeObject> envelop)

Returns the native object instance inside an envelop.
It can be called only from org.pepstock.charba.client package.

Parameters:

envelop - envelop instance which will contain the native object

Returns:

the envelop, passed as argument, loaded with the native object

getChart

public final IsChart getChart()

Returns the chart instance

Returns:

the chart
