Hi there, you should be able to do this by manually swapping the x-axis and y-axis properties.
I was able to do this by swapping the xAxes and yAxes props of a the xy chart in bar mode, and then within each series of the series prop swap the xAxis and yAxis props and then the data.x and data.y props and this should give you your chart rendered horizontally.
This is what my props look like after doing this to the default xy chart component as it is when you first drag it onto a View and changed each series to render as a column.
