Stacking Multiple 2D plots in one 3D plot

Hi,

I have 14 two dimensional plots and I want to show them all in a 3D plot like this:

I can plot the 14 plots in the same 2d plot but I want to have an offset between them and plot them in a 3d plot.

 figure(1)
    for i=1:size(nw,1)
        h_FDD_dB(i) = plot(f_FDD,pow2db(SV_FDD{i,1}),'DisplayName',['SV1, No. of windows: ',num2str(i)]);
        xlabel('Frequency (Hz)');
        ylabel('Singular Value (Power Spectral Density)(dB)');
        title('Singular Values of the SD Matrix')
        xlim([0 60])
        legend
        hold on
        grid on
    end
    legend(h_FDD_dB);
    

nw = 1:1:14;

and f_FDD & SV_FDD{i,1} are 65537*1 vectors.

Thanks,

Amir

Check out the following resources. If you get stuck implementing a solution, share your updated code and we can help you get unstuck.

• waterfall plots
• Ridgeline visualizations
• Simple 3D plot using plot3()
• Another waterfall plot on the file exchange

Hi Adam,

This is very similar to what I wanna do:

I have trouble defining my variables though. My data is stored in cell arrays instead of just one table and I'm confused how to apply your solution to my problem. I'd really appreciate it if you could help me.

Thanks,

Amir

You can also do it in a loop.

It will look something like this (not tested).

 figure(1)
 hold on
    for i=1:size(nw,1)
        h_FDD_dB(i) = plot3(i,f_FDD,pow2db(SV_FDD{i,1}),'DisplayName',['SV1, No. of windows: ',num2str(i)]);
    end
    legend(h_FDD_dB);
    
    xlabel('Number of windows')  % ???
    ylabel('Frequency (Hz)');
    zlabel('Singular Value (Power Spectral Density)(dB)');
    title('Singular Values of the SD Matrix')
    ylim([0 60])  %???
    grid on
    view(3)

I get the "Vectors must be the same length." error, that's where I get confused.

[Adam Danz]

Instead of plot3(i,..., replace i with repmat(i,size(f_FDD))

[Amir Hosein Shokouhy]

Perfect, thank you!

[Adam Danz]

Great! You can also switch the first and second inputs to control whether the data vary across the X or y axes.

I'll give it a try, thanks again Adam!
