Fake Waterfall Plots

Creating a real waterfall plot requires a 2D wave. If your data is in the form of 1D waveforms or XY pairs,

it may be simpler to create a "fake waterfall plot".

In a fake waterfall plot, you plot your waveform or XY data using a regular graph and then create the water-

fall effect by offsetting the traces. Since fake waterfall plots use regular Igor traces, you can control their

appearance the same as in a regular graph.

The result, with hidden line removal, looks like this:

NOTE: Because of the offsetting in the X and Y directions, the axis tick mark labels can be misleading.

Igor includes a demo experiment showing how to create a fake waterfall plot. Choose File
