Constructor Detail

Annotation

public Annotation(ChartNode parent,
          Image img,
          double x,
          double y)

Renders an Image object centered at an x,y location in chart coordinates.

Parameters:

parent - the ChartNode parent of this data node, usually an Axis object

img - the Image object to draw

x - the x location in user coordinates

y - the y location in user coordinates

Annotation

public Annotation(ChartNode parent,
          String string,
          double x,
          double y)

Draws a String at the specific x,y location in chart coordinates.

Parameters:

parent - the ChartNode parent of this data node, usually an Axis object

string - the String to draw

x - the x location in user coordinates

y - the y location in user coordinates

Annotation

public Annotation(ChartNode parent,
          Text text,
          double x,
          double y)

Creates a Text object at the specific x,y location in chart coordinates.

Parameters:

parent - the ChartNode parent of this data node, usually an Axis object

text - the Text object to draw

x - the x location in user coordinates

y - the y location in user coordinates

Method Detail

getText

public Text getText()

Gets the Text for this Annotation object.

paint

public void paint(Draw draw)

Paints this node and all of its children. This is normally called only by the paint method in this node's parent.

Overrides:

paint in class Data

Parameters:

draw - the Draw object to be painted

setLocation

public void setLocation(double x,
               double y)

Update the location of this Annotation instance.

Parameters:

x - a double specifying the new x location in chart coordinates.

y - a double specifying the new y location in chart coordinates.

setString

public void setString(String string)

Sets the String for the Text object to render.

Parameters:

string - the new String value

setText

public void setText(Text text)

Sets the Text object to render.

Parameters:

text - the new Text object
