Constructor Summary

protected	ExtendedChart() Creates new empty DefaultChart.
	ExtendedChart(ChartDataModel model, java.lang.String title) Creates a new DefaultChart with the given model and title string and no coordinate system.
	ExtendedChart(ChartDataModel model, java.lang.String title, int coord) Creates a new DefaultChart with the given model and title string and a coordinate system.
	ExtendedChart(ChartDataModel model, java.lang.String title, int coord, java.lang.String xaxis, java.lang.String yaxis) Creates a new DefaultChart with the given model and title string and a coordinate system.

Method Summary

java.awt.Dimension	getPreferredSize() Should compute the preferred size of the Chart
void	render(java.awt.Graphics2D g) Does the layout of the title, legend and coordinate system and calls the render method of all those including the ChartRenderers.
void	zoom(java.awt.Rectangle area) Zooms in on a specified rectangle area of the chart by setting the max and min values to display.

Constructor Detail

ExtendedChart

protected ExtendedChart()

Creates new empty DefaultChart.

ExtendedChart

public ExtendedChart(ChartDataModel model,
                     java.lang.String title)

Creates a new DefaultChart with the given model and title string and no coordinate system.

Parameters:

model - the ChartDataModel

title - the title String

ExtendedChart

public ExtendedChart(ChartDataModel model,
                     java.lang.String title,
                     int coord)

Creates a new DefaultChart with the given model and title string and a coordinate system.

Parameters:

model - the ChartDataModel

title - the title String

coord - the id of the coordinate system configuration

ExtendedChart

public ExtendedChart(ChartDataModel model,
                     java.lang.String title,
                     int coord,
                     java.lang.String xaxis,
                     java.lang.String yaxis)

Creates a new DefaultChart with the given model and title string and a coordinate system.

Parameters:

model - the ChartDataModel

title - the title String

coord - the id of the coordinate system configuration

xaxis - the x-axis' unit

yaxis - the y-axis' unit

Method Detail

getPreferredSize

public java.awt.Dimension getPreferredSize()

Should compute the preferred size of the Chart

Returns:

null

render

public void render(java.awt.Graphics2D g)

Does the layout of the title, legend and coordinate system and calls the render method of all those including the ChartRenderers.

Specified by:

render in interface Chart

Specified by:

render in interface Renderer

Overrides:

render in class AbstractChart

Parameters:

g - the Graphics2D object to paint in.

zoom

public void zoom(java.awt.Rectangle area)

Zooms in on a specified rectangle area of the chart by setting the max and min values to display. This routine will have no effect if autoscaling is enabled. The area to zoom to is specified in terms of the graphics coordinates (the transform to data coordinates is performed here).

Parameters:

area - A Rectangle specifying the area in graphics coordinates to zoom
