For bar graphs only, this property sets the spacing between bars within a group (clusters) in a side-by-side bar graph. A larger number creates more space between bars within a group. When this property is set to zero, there is no space between the bars and all bars in the group will touch each other. When this property is set to 100, bars in a group are as far apart as possible.

Is any integer between -1 and 100. 0 is the default value.
