This is a Bridge Chart, also called a Waterfall chart. It is usually used to show how a value changes from the initial value to the final value through a series of intermediate up or down changes. The initial value and final value are usually represented by columns based at Y=0, with intermediate changes shown as floating columns. The floating columns are shown in two different colors to help differentiate up and down changes.
Bridge Chart is supported from Origin 2018. Please refer to this help page.
