Summary: XYBarRenderer does not render bars on LogarithmicAxis

Initial Comment:
When using an XYBarRenderer and a LogarithmicAxis on
the range, the bars are not drawn.  Instead, their
outline is drawn at the Y-value and nothing extends to
the baseline.

Example:

import java.util.Date;

import javax.swing.JFrame;

import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.axis.DateAxis;
import org.jfree.chart.axis.LogarithmicAxis;
import org.jfree.chart.plot.XYPlot;
import org.jfree.chart.renderer.xy.XYBarRenderer;
import org.jfree.data.time.Second;
import org.jfree.data.time.TimeSeries;
import org.jfree.data.time.TimeSeriesCollection;

public class Test
{
	public static void main(String[] args)
	{
		TimeSeries series = new TimeSeries("series",
Second.class);
		for(int i = 0; i < 100; i++)
			// Add a value between 1 and 10^10 every second
			series.add(new Second(new Date(i * 1000)),
Math.pow(10, Math.random() * 10));
		TimeSeriesCollection dataset = new
TimeSeriesCollection(series);
		XYPlot plot = new XYPlot(dataset, new DateAxis(), new
LogarithmicAxis(""), new XYBarRenderer());
		JFreeChart chart = new JFreeChart(plot);
		ChartFrame frame = new ChartFrame("", chart);
		frame.pack();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setVisible(true);
	}
	
}
