In the future, you can scan through the list of plots in the Plots tab of the toolstrip for one whose thumbnail looks similar to the type of plot you want. This may help you identify a useful function. Even if it's not exactly what you're looking for, you may be able to adjust properties of that plot or use one of the plotting functions in the See Also section of that function's documentation page to get closer.
That's not a waterfall plot, at least not by my understanding. To me a waterfall plot looks like the picture shown on the waterfall function documentation page.
What you've shown looks more like the "Plot Multiple Lines" or "Create Line Plot From Matrix" examples on the documentation page for the plot function, though your multiple lines look like their Y data is different enough that the lines don't overlap. In that I agree with Adam Danz, that plot is probably the right tool for this job.
If neither of those look like what you want, open the Plots tab on the Toolstrip and click the downward pointing triangle in the PLOTS section. Scan through the thumbnails to see if one looks like what you want. Once you've found such a thumbnail ask for help or doc on the function name written under the picture, or open up the Catalog (the button in the lower corner of the PLOTS dropdown) and locate the thumbnail / function of the same name to see the documentation page for that function.
