[Dynamically change the Bar Chart width]

Hi,

  I used iReport and jasper to create a bar chart which displays some graphical information depending on the user selection in the system.The number of bars in the bar chart get changed depending on the query results at each time.Being the defined chart width is a fixed value the bar width in the chart get changed each time.When there is only one bar in the chart, that bar is taking the full width from the chart width. So I want to dynamically change the chart width depending on the sql query results, or is there any way to keep the individual bar width fixed?

Thank You
