Select at least one Y column (or a range from at least one Y column). Ideally, select at least two Y columns (or a range of at least two Y columns). If there is an associated X column, X column supplies X values; otherwise, sampling interval of the Y column or row number is used.
From the menu, choose Plot > 3D: Walls: 3D Stacked Walls.
(Installed to the Origin program folder)
Unlike 3D Wall graph which plots each Y column into a wll and positions each wall side by side, 3D stacked wall graph stacks Y columns in one wall, which height means the culmulation of Y values.
