Hey everyone!
I am struggling to plot a 3d graph like the photo that I attached. I have multiple data stating the number of people attending different event over a period of time. Therefore I hope to plot the number of people(z-axis) over the number of days (x-axis). And the different set of data will be plotted side by side along the y axis like shown in the 2 examples tt I showed.
I need help and advice on how I can plot these data, and also shade them in different color to differentiate them!
Thank you for your help in advance!!

Ran in:
Something like this:
z1 = rand(10,1) ;
z2 = rand(10,1) ;
x1 = 1:length(z1) ;
x2 = 1:length(z2) ;
y1 = repmat(1,size(x1)) ;
y2 = repmat(10,size(x2)) ;
figure
hold on
patch(x1,y1,z1,'r') ;
patch(x2,y2,z2,'b') ;
view(3)

Thank you for your help! However, my y axis only have 4 events. And when i input my x=0:100, y=[1 2 3 4], z=[1:100], patch(x,y,z), i will get an error where my matrix is not equal. Is it my y axis that is wrong?
P.S. Pretty new to this, so I don really understand some stuff.

It will definitely throw error. To use patch all x, y, z should be of same dimension. But still, for your data it will not form a region/ area. It will be a striaght line and you cannot see any colored region.
x=0:100 ;
y= linspace(1,4,length(x)) ;
z=[0:100];
patch(x,y,z),

Have a look at the FEX-submission joyplot, it should give you functions to make these types of plots.

Thanks! This is really a good function to study!
