.XY SET BAR GAP:BTW

This subroutine sets the gap between the bars in a bar chart layer.

Usage:

      PASS         <bar_gap>                  FIELD            SHARE? N
      GOSUB    0CD .XY SET BAR GAP:BTW
      *        Check for error 
      IF       0CD .XY SET BAR GAP:BTW        NE

Description:

<bar_gap> - The portion of the space between the bars (or between bar groups for multi-bar layers).

The gap between the bars is expressed as the portion of the space between the bars. For example, a bar gap of 0.2 means 20% of the distance between two adjacent bars is the gap between the bars. A bar gap of 0 means there is no gap in between the bars. The bar gap can be negative. In this case, the bars will overlap.

Values greater than or equal to 1 will result in one pixel wide bars, since 100% of the space is allocated to the gap. The larger the gap, the narrower the bars have to be to fit in the space.
