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.
Select required data.

WATERFAL.OTP (installed to the Origin program folder).
The waterfall graph is ideal for comparing variations between multiple data sets created under similar conditions. The graph has a pseudo-3D effect, enabling you to see variations in the Z direction. Also, the color is mapped along the Z direction.
Each data set is displayed as a line data plot which is offset by a specified amount in both the X and Y direction. For details on how to customize this plot, please refer to this help topic: Customizing Waterfall Plots.
