Is there any way I can reduce the spaces between the bars in a group. I used sgplot for horizontal bar charts which are stacked. I will appreciate any help
The number of bars in the graph determines the midpoint spacing. This is the spacing between the center of the bars. The bar width itself is 85% of the midpoint spacing by default. You can set that fraction to anything between 0-1. Bar spacing of 1 means the bars will touch each other.
Set the BARWIDTH option between 0 and 1 (1 meaning no space between the bars, close to zero meaning lots of space).
It could be discreteoffset:
discreteoffset=...
You can find plenty of examples for all graphs here:
