Answer 1

I'm using the following workaround:

StandardXYItemRenderer renderer = new StandardXYItemRenderer() {
    private static final long serialVersionUID = 0L;

    @Override
    public LegendItem getLegendItem(int datasetIndex, int series) {
        LegendItem legend = super.getLegendItem(datasetIndex,
                series);
        return new LegendItem(legend.getLabel(),
                legend.getDescription(), legend.getToolTipText(),
                legend.getURLText(), Plot.DEFAULT_LEGEND_ITEM_BOX,
                legend.getFillPaint());
    }
};

...

plot.setRenderer(renderer);

A LegendItem infers its Shape from the corresponding series, which can be changed as shown here. This related example shows one way to render a LegendItem in an external component.
