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.
