Add the Stack plugin to draw several bar series side-by-side as shown in the following example:
Also, specify the stacks property to draw series one under another:
The Stack plugin allows you to customize the series order and offset. In the following example, a stacked area series is used to create a streamgraph. Order and offset values are calculated by calling the d3-shape library. Then, these values are passed to the Stack plugin's order and offset properties.
