About the function 'bar3', I want put the bar figure in the center of the cell.

We can see the second figure, the bars are not in the cells, How can I move them into the cells?

Help me, please.

it bothers me for a long time! ! !

Other than the rasterization issues owing to the orientation, I don't understand the perceived problem nor the desired result.

I'm sorry for that @dpb, This is my first time to ask a question on the internet. I'm a bit exciting! My question is if I can put the bars into the unit of the coordinate.The same meaning as what 'the cyclist' say.

Sorry, I deleted my original comment accidentally. Lilian wants to be able to specify the (x,y) locations of the bars.

YES，you are right！

In the documentation, I don't actually see a method to specify the (x,y) coordinates of the bins. However, you can set the labels, which might be good enough:

figure
bar3(rand(3,2))
set(gca,'XTickLabel',[5 6],'YTickLabel',[12 13 14])

Here is the result:

I noticed that, too...peculiar oversight it would seem. There is an optionally given input y vector, but no way to give x. Have to admit in 30 yrs never had call to use it, though...

Thanks a lot, I may have found another method to draw the bars, After I solved it, I will give the answers to you. Thanks again!!!

Might want to search File Exchange for submissions--maybe somebody else has previously been frustrated and already solved the problem.

[Lilian]

My solution is a little stupid,I used the 'patch' function to solve this problem.

I don't believe the bar3 command allows you to specify both X and Y. However, the bar3 command creates surfaces, and you can specify the XData and YData for surfaces. You could try something like this:

data = ones(10);
x = 1.5:10.5;
h = bar3(x,data);
for i = 1:10;
  set(h(i),'XData',get(h(i),'XData') + 0.5);
end
xlim([1 11])
ylim([1 11])
zlim([0 10])

Thanks@Benjamin Kraus, But my problem is that I create the surface firstly,After that I use the bar3 function.
