3D grouped bar graph

Hi I have two grouped bar graphes. The first one is for x=1 and the second one is for x=2. I want to combine both at the same with a 3D view. My code is here

clear all
clc
close all

%at x=1

a=[11;7;14;11;43;38];
b=[11;13;17;13;51;46];
c=[9;11;20;9;69;76];
y1=[a b c];

%at x=2

d=[38;61;75;38;28;33];
e=[46;132;135;88;36;51];
f=[76;186;180;115;85;72];
y2=[d e f];

figure(1)
bar3(y1,'grouped')
title('Grouped Style')
ylabel('y1')
zlabel('z1')

figure(2)
bar3(y2,'grouped')
title('Grouped Style')
ylabel('y2')
zlabel('z2')

Any help is appreciated!

Thank you

I ran into the same problem. I was able to solve it by using the Xdata of the plot as described for a different case here:

https://stackoverflow.com/questions/28991376/how-to-set-x-and-y-values-when-using-bar3-in-matlab

I would suggest you try this:

clear all
clc
close all

%at x=1

a=[11;7;14;11;43;38];
b=[11;13;17;13;51;46];
c=[9;11;20;9;69;76];
y1=[a b c];

%at x=2

d=[38;61;75;38;28;33];
e=[46;132;135;88;36;51];
f=[76;186;180;115;85;72];
y2=[d e f];

figure(1); 
hold on;

%First x value
xval = 1; 
h = bar3(y1,'grouped');
Xdat = get(h,'Xdata');
for ii=1:length(Xdat)
    Xdat{ii}=Xdat{ii}+(xval-1)*ones(size(Xdat{ii}));
    set(h(ii),'XData',Xdat{ii});
end

%Second x value
xval = 2;
h = bar3(y2,'grouped');
Xdat = get(h,'Xdata');
for ii=1:length(Xdat)
    Xdat{ii}=Xdat{ii}+(xval-1)*ones(size(Xdat{ii}));
    set(h(ii),'XData',Xdat{ii});
end

xlim([0 3]);
view(3);
title('Grouped Style')
xlabel('x');
ylabel('y');
zlabel('z');

Dear all, I want to plot a 3D bar graph for a given X Y Z row matrix. actually I want to plot bar of Z for a specified X and Y. How to plot it please help me.

Thank you for this Sam Penwell, I was facing the same issue and your approach was very helpul.

I think the only way is to group data into one matrix (bar2 groups data row-wise)

figure(1)
bar3([y1,y2],'grouped')

[friet]

Thanks for your reply. However, I want to group the second set of data in x direction. With

bar3([y1,y2],'grouped')

I group y1 and y2 at the same x - axis. I want y1grouped at x=1 and y2 at x=2. Like in the figure below but grouped.Please help!

Thanks

[Massimo Zanetti]

As far as I know, it is not possible to have groups with different "x" coordinate. Looking forward to see if someone else can solve it.

[ALEX CHICAIZA]

Help I need similar but "stacked". How I can do it?
