How can I create this 2D waterfall plot?

The data is from a CSV file with one time column and 32 columns of data.

The curves show the Amplitude vs. Time behavior of the sensors while the sensor locations (in meters) are placed on the Y-axis.

I assume this is a waterfall plot, but I can't reproduce it. How can I make a graph like this one?

What happens when you just plot out the data like this?

plot(time, data)

where 'time' is your time vector and 'data' is your 32-column matrix?

[onamaewa]

I tried plotting the data using:

figure()
[X, Y, Z] = signal(time)), position, signal(amplitude)

waterfall(x, y, z)

It didn't work.

[Adam Danz]

I don't know what "it didn't work" means. Does that mean you got at error? Does that mean the plot produced something unexpected?

Did you try the simple plot I suggested?

What do your data look like? How are they organized? Is each column of your matrix one of the lines that is represented in the graph you shared?

I'm working with virtually 0 information so it's hard to make suggestions or to help you without (much) more info.

Update: a recent file exchange pick-of-the-week resembles a waterfall plot but does not resemble the image in the question.

Answer 1

[Steven Lord]

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.

That plot does look like a waterfall plot. You can obtain a plot like that by trying

figure()
waterfall(time,position,data)

Here time is your time vector and position is a 1x32 vector that corresponds to each column of your data. Make sure the matrix "data" is of the correct dimensions (length(time) x 32). You may rotate the resulting waterfall plot to get what is shown in the figure. Good luck!

I am wondering what is the solution? How to obtain this chart? I have the same problem =)

Try stackedplot built-in plotting routine

[Adam Danz]

The use of stackedplot is not a solution in this case because each line in the demo image extends into the territory of the next line along the y-axis. With stackedplot, each line would have its own ylim which would prevent overlaping.
