Stacked horizontal bar chart

TIP

For core principles, concept description, API and changelog, refer to the D3 chart.

Horizontal bar

You can rotate a chart using the <HorizontalBar/> component by swapping scaleBand and scaleLinear. See more about scaleBand and scaleLiner in the Bar chart guide.

Horizontal stacked bar

To draw a horizontal stacked chart, use the <StackBar.HorizontalBar/> component.
