对bar进行分组 [英] Grouping bar3 plots like bar

问题描述

我想知道是否有可能将bar图的相同分组行为转化为bar3. 例如，如果您绘制

I'm wondering if it is possible to get the same grouping behavior of bar plots into bar3. For example, if you plot

  bar(rand(3));

您每点获得3条； bar将每个 x 的不同 y 值分组.现在，我想对3D数据执行相同的操作.那就是我想将几段2D数据可视化为条形图组.然后，如果我的数据是

you get 3 bars for each point; bar groups the different y values for each x. Now I would like to do the same with a 3D data. That is that I have several slices of 2D data that I want to visualize as groups of bars. Then, if my data is

data = rand(3,3,2);

我希望将data(1,1,:)看成一组条形图，而将data(1,2,:)看成另一组条形图，依此类推.

I would like to see data(1,1,:) as a group of bars, and data(1,2,:) as another group and so on.

有可能吗?我找不到实现此目标的方法.

Is it possible? I cannot find a way of achieving this.

编辑:我要添加更多详细信息，以便对其进行更好的解释.

I'm adding more details, to explain it better.

让我们说我们有两组或更多组数据{x_(i,j)^s}.我需要的是将所有集合s都放在同一个网格位置(i,j)中.在此问题中，他们将数据集并排分组，而不是元素分组-wise，像这样:

Lets said that we have two, or more, sets of data {x_(i,j)^s}. What I need is to group in the same grid position (i,j), all the sets s. In this question, they are grouping the data sets side by side, not element-wise, like this:

x1(s1) x1(s2) x1(s3)   x2(s1) x2(s2) x2(s3)   x3(s1) x3(s2) x3(s3)
x4(s1) x4(s2) x4(s3)   x5(s1) x5(s2) x5(s3)   x6(s1) x6(s2) x6(s3)
x7(s1) x7(s2) x7(s3)   x8(s1) x8(s2) x8(s3)   x9(s1) x9(s2) x9(s3)

我想要bar命令的行为，当放置多个数据集时，它倾向于分组.我想知道是否有可能.

I would like the bar command behavior, it tends to group when putting more than one data set. I would like to know if it is possible.

推荐答案

我不确定我是否完全理解，但是如果您正在寻找像bar(rand(3))所述的分组行为，则可以尝试

I am not sure I fully understood, but if you are looking for grouped behavior like you mention with bar(rand(3)) then you can try

figure; bar3(rand(5),'grouped');
% or maybe
figure; bar3(rand(5),'stacked');

或尝试重新排列数据中的数据，以便它可以与带有重塑形状的bar3一起更好地工作:

or try to rearrange the data in data so it can work better with bar3 with reshape:

data = rand(3,3,2);
% now each data(i, j, :) will be in single row 
changeddata = reshape(data , [size(data , 1)*size(data , 2) 2]);
figure; bar3(changeddata);
figure; bar3(changeddata ,'grouped');
figure; bar3(changeddata ,'stacked');

也许您可以给出一个示例代码来说明如何将其放在一组中，这将有助于更好地理解您的问题.

Maybe if you can give a code example for how it's supposed to look in one group, it would help to understand your question better.
