Constructor Detail

PlotCanvas

public PlotCanvas(ConfigParameters config)

Creates an instance from the specified configuration parameters.

Key & Default Value	Type	Mandatory	Description
horizontalAnchor = center	String	no	Horizontal position of the paper relative to the device border. Possible values are left, center, and right.
paper = 0, 0, 1, 0.6	double[]	no	Rectangle defining the paper. The first two values determine the x- and y- coordinates (in device-independent units) of the lower-left corner. The last two values determine the upper-right corner.
plot = default values of Plot	ConfigParameters	no	Definition of the Plot.
verticalAnchor = center	String	no	Vertical position of the paper relative to the device border. Possible values are top, center, and bottom.

Note, that this instance registers itself at the wrapped Plot instance.

Method Detail

getPaper

public ClippingRectangle getPaper()

Returns the paper definition.

getHorizontalAnchor

public Anchor getHorizontalAnchor()

Returns the horizontal anchor.

getVerticalAnchor

public Anchor getVerticalAnchor()

Returns the vertical anchor.

getPlot

public Plot getPlot()

Returns the plot.

connect

public void connect(DataPlot dataPlot)

Connects the wrapped Plot instance with the specified DataPlot.

Parameters:

dataPlot - Data to be connected with this plot canvas. Can be null in order to disconnect this instance from a DataPlot.

plotChanged

public void plotChanged(PlotEvent event)

Handles the spcified event. Here nothing is done. But subclass may override this method.
