If your problem is that you only see very thin chart columns separated by a large amount of whitespace then you need to set the Series Expression to some static value, like "my Static Value"

People...

 

I had to implement a Customizer Class and setting it up into the "Chart Properties", attribute "Customizer class" as follow

 

I hope it helps...

 

Code:

import net.sf.jasperreports.engine.JRAbstractChartCustomizer;
import net.sf.jasperreports.engine.JRChart;

import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.CategoryPlot;
import org.jfree.chart.renderer.category.BarRenderer;

public class CustomizeBarChart extends JRAbstractChartCustomizer {

    public void customize(JFreeChart chart, JRChart jasperChart) {
	CategoryPlot categoryPlot = chart.getCategoryPlot();
	BarRenderer renderer = (BarRenderer) categoryPlot.getRenderer();
		
	//Spaces between bars
	renderer.setItemMargin(0.03);		
    }
}

Warning: you need to know some Java to create or modify chart customizers. If you want a simple introduction, then these articles of mine should help:
