Waterfall (Vue)

Waterfall charts help in understanding the cumulative effect of sequentially introduced positive or negative values. The Waterfall chart is also known as a "flying bricks" chart or Mario chart due to the apparent suspension of columns in mid-air.

This sample shows how to create a Waterfall chart, as well as how to use the connectorLines property to connect the bars and the total increase/decrease of the chart using the showTotal property.
