Method Detail

draw

void draw(Graphics2D g,
        Rectangle r)

This method draws a ChartService in a specific area.

Parameters:

the - graphics where it will be painted and the area of it to be draw

toSerieValue

Object toSerieValue(int idSerie,
                  int pixelX)

toXPixelValue

int toXPixelValue(int idSerie,
                Object value)

toCategoryValue

Object toCategoryValue(int idSerie,
                     int pixelY)

toYPixelValue

int toYPixelValue(int idSerie,
                Object value)

getChartDataSet

ChartDataSet getChartDataSet()

Obtains the ChartService's data that is used on the chart

Returns:

ChartDataSet

setChartDataSet

void setChartDataSet(ChartDataSet data)

Insert a ChartDataSet to the service

Parameters:

the - ChartDataSet to be drawn by the ChartService

getChartProperties

ChartProperties getChartProperties()

Get the ChartService's definition using a ChartProperties object.

Returns:

ChartProperties

getChartRenderingInfo

ChartRenderingInfo getChartRenderingInfo()

getChartEditor

ChartEditor getChartEditor()

getChartType

String getChartType()

Get the ChartService's type.

Returns:

a String with the ID of the kind of Service

getChartName

String getChartName()

Get the name of the service

Returns:

the ChartService's name

getInnerChart

Object getInnerChart()

Useful to swing part. The idea is: If someone wants to implement his own ChartService using un underlaying library, the main object can be reached by this method. In our case, the object will be a JFreeChart, but if not, the Swing library can make its own cast.

Returns:

the inner object that the library uses to render.

getRenderer

ChartRenderer getRenderer()

It gets the renderer used to drawn the chart.

Returns:

the ChartService's renderer

Returns a ChartRenderer using its ID

Parameters:

ChartRenderer's - name

Returns:

the ChartRenderer with the ID indicated in the name

hasDomainAxis

boolean hasDomainAxis()

Returns:

a boolean depending if it has a DomainAxis or not

hasRangeAxis

boolean hasRangeAxis()

Check if it has a RangeAxis (ValueAxis)

Returns:

a boolean depending if it has a RangeAxis or not

getDomainAxis

List<ChartAxis> getDomainAxis()

Useful to get the DomainAxis of a ChartService
