Groupwidth is not changing the width of a column chart

[David Buch]

Hi

I have a column chart with 6 groups in it. However No matter what I do, the gap between each group remains the same, and is huge. whatever I try and change only changes the widths of individual bars or the chart itself, but the gap between the groups remains constant all the time.

Please help!! I have tried any number of combinations of the following:

,bar :{groupWidth: '60%' , group:{gap:'10px'}, gap: '5px', width: '100%'}

,bar:{ group:{width : '100%'}, gap: '10' ,width: '60' }

,chartArea:{left:60,top:20,width:'100%'}

,vAxis: {viewWindowMode:'pretty'}

,hAxis: {viewWindowMode:'pretty', slantedText:'true'}

thanks!!
