Plotting Waterfall graph problem

Make/N=5 wave0=p, wave1=1+p, wave2=2+p
Concatenate {wave0,wave1,wave2}, matrix
Edit matrix
NewWaterfall matrix
Make/N=5 xWave = 10*p
NewWaterfall matrix vs {xWave,*}

You can check the dimensionality of your waves using Data->Browse Waves.

I tried these commands and it seems to work fine:

Make/N=5 wave0=p, wave1=1+p, wave2=2+p
Concatenate {wave0,wave1,wave2}, matrix
Edit matrix
NewWaterfall matrix
Make/N=5 xWave = 10*p
NewWaterfall matrix vs {xWave,*}

In your case Igor's built-in waterfall plot will probably work fine. If you had a different X wave for each Y wave, I would recommend a fake waterfall plot.

But I don't quite understand what the first command line means.

// Make 3 1D waves names wave0, wave1, wave2 with 5 points each
Make/N=5 wave0=p, wave1=1+p, wave2=2+p
// Display the waves in a table
Edit wave0, wave1, wave2
// Create a 2D wave named matrix by concatenating the 3 1D waves
Concatenate {wave0,wave1,wave2}, matrix
// Display the 2D wave in a table
Edit matrix
// Create a waterfall plot of the 2D wave
NewWaterfall matrix
// Create a 1D X wave to control the X axis of a different waterfall plot
Make/N=5 xWave = 10*p
// Create a waterfall plot using a 2D Y wave and a 1D X wave
NewWaterfall matrix vs {xWave,*}
