Is there a user-accessible mechanism for controlling intra-group density in grouped bar plots?

Motivation: I'm finding inter-group spacing is smaller than I'd prefer for some applications, particularly when the number of bars per group is large.
Aiming to improve visual separation of the groups by increasing intra-group density.
So far ...
  • I had initially guessed that setting the 'BarWidth' parameter during call to bar might have automatically triggered a reduction in offsets around the nominal x-values. This doesn't appear to be the case.
  • I seem to be able to get/set 'XOffset' but to no effect.
  • Direct control of bar polygons?: 'XEndPoints' appears to be read-only.
Cheers

Thanks Monisha.
The main problem may have been my question.
The edited version is more generally motivated and is easily illustrated, I hope.
Please find attached an .mlx file.
Cheers

Hi Amos,
Right now how bar plot works is, each bar is asigned a specific width and each group is assigned a specific width. So changing the width of bar in group increases or decreases the intra-grouping space. There is no option for increasing the inter-group spacing.
But as an workaround to increase the inter-group space, add a column with 0 value at end of matrix so it creates extra space for bar which is empty.
As an example
m=rand(5,5)-0.5;
a=size(m);
m=[m zeros(a(1,1),1)];
bar(m,1)
