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.
