public abstract class ChartNode
extends AbstractChartNode

The base class of all of the nodes in the 2D chart tree.

It may be desirable to enable anti-aliasing on a particular ChartNode. This can be accomplished in the following way:

 AxisXY axis = new AxisXY(chart);

 RenderingHints hints = new RenderingHints(RenderingHints.KEY_ANTIALIASING,
      RenderingHints.VALUE_ANTIALIAS_ON);
 axis.setAttribute("RenderingHints", hints);

paint

public abstract void paint(Draw draw)

Paints this node and all of its children.

Parameters:

draw - the Draw object to be painted

prePaint

public void prePaint()

The prePaint method is called in all nodes in a chart just before the chart is painted. The default implementation does nothing. Override this method to do computations just before painting in a chart node.

removePickListener

public void removePickListener(PickListener pickListener)

Removes a PickListener from this node.

Parameters:

pickListener - the PickListener to be removed from this node

setALT

public void setALT(String value)

Sets the value of the "ALT" attribute. The "ALT" attribute is used when client-side image maps are generated. A client-side image map has an entry for each node in which the chart attribute HREF is defined. Some browsers use the alt tag value as tooltip text. *

Parameters:

value - "ALT" value.

setBarGap

public void setBarGap(double value)

Sets the value of the "BarGap" attribute. This is the gap between bars in a group. A gap of 1.0 means that space between bars is the same as the width of an individual bar in the group.

Parameters:

value - the double "BarGap" value

setBarType

public void setBarType(int value)

Sets the value of the "BarType" attribute.

Parameters:

value - an int which specifies BarType. Legal values are BAR_TYPE_VERTICAL or BAR_TYPE_HORIZONTAL.

See Also:

BAR_TYPE_VERTICAL, BAR_TYPE_HORIZONTAL

Sets the value of the "BarWidth" attribute. This is the width of all of the groups of bars at each index.

Parameters:

value - the double "BarWidth" value.

setChartTitle

public void setChartTitle(ChartTitle value)

Sets the value of the "ChartTitle" attribute. This is effective only in the Chart node, where it replaces the existing ChartTitle node. The Chart node constructor creates a ChartTitle node and uses it to define its "ChartTitle" attribute, so there is generally no need to call this routine.

Parameters:

value - ChartTitle node

setClipData

public void setClipData(boolean value)

Sets the value of the "ClipData" attribute. This indicates that the data elements are to be clipped to the current window.

Parameters:

value - "ClipData" value

See setGradient(java.awt.Color,java.awt.Color,java.awt.Color,java.awt.Color) for details on the interpretation of these colors.

setGradient

public void setGradient(Color colorLL,
