CFCHART Style --Horizontal Bar Chart Width

I am trying to add some style to a CFCHART Bar Chart.

I have found an.xml file that I can add style.

Is there a style to set the widths of a bar in a bar chart?

Right now the bar width is to much and an 8 bar horizonntal chart takes up the entire page.

Is there a way to make the bar chart width smaller.

AND is there a place wher I can change other styles?
