Excel Space between bars of excel chart

[kiruking007]

Hi friends!

Is there any way to decrease the gap between bars (NOT the width of the bars) of excel bar chart?
I made a bar chart with 23 dates (weeks like 10/5/2007, 10/12/2007, 10/19/2007 etc.). The row were very thin and the gap between the rows is long. Can we decrease the gap between the bars to make it look good?

Thanks in advance!
