bar_gap | [RW] | Whether to have a gap between the bars or not, default is true, set to false if you don‘t want gaps. |
stack | [RW] | How to stack data sets. :overlap overlaps bars with transparent colors, :top stacks bars on top of one another, :side stacks the bars side-by-side. Defaults to :overlap. |
Ensures that :fields are provided in the configuration.
