Method Details

renderChart

public boolean renderChart(Graphics border,
 Dimension dimension,
 Graphics plot,
 Insets borderInsets)
                    throws ChartRenderException

Render the graph into the given graphics handle. Two are given since this may be used with nested windows, i.e. with the plot within the border. If this IS the case, then the border insets are needed to define where on the border to draw axis, etc.

Parameters:

border -

plot -

borderInsets -

Returns:

Throws:

ChartRenderException

renderChart

public boolean renderChart(Graphics g,
 Dimension dimension)
                    throws ChartRenderException

Render the chart onto a single graphics handle. Calculate required border insets and use accordingly ...

Specified by:

renderChart in class PamChartRenderer

Parameters:

g -

Returns:

Throws:

ChartRenderException

calculateInsets

public Insets calculateInsets(Graphics g)

renderborder

public boolean renderborder(Graphics g,
 Dimension dimension,
 Insets plotInsets,
 boolean drawBox)

Render the plot border. The insets for the plot are (probably) never null since they are needed to inform where to paint the axis.

Parameters:

g -

plotInsets -

Returns:

renderPlot

public boolean renderPlot(Graphics g,
 Dimension dimension,
 Insets plotInsets)
                   throws ChartRenderException

Render the plot. If the graphics handle for this plot is different to that of the border, then it's likely insets will be 0 or null. If it's a single graphics object the whole thing is being written to, then the insets will need to be no zero to allow for axis.

Parameters:

g - graphics handle to plot area

dimension - plot dimensions

plotInsets - plot insets

Returns:

OK if drawn

Throws:

ChartRenderException

renderKey

public boolean renderKey(Graphics g,
 Dimension dimension,
 Insets plotInsets)

Draw the key on the main plot area.

Parameters:

g - graphics handle to plot area

dimension - plot dimensions

plotInsets - plot insets

Returns:

OK if drawn
