绘制单元格阵列 [英] Plotting a cell array

问题描述

我需要在Matlab中绘制具有以下格式的单元格数组:

I need to plot a cell array with the following format in Matlab:

{[vector1], [vector2], ...}

进入二维图，其中向量的索引为y，向量的索引为x

Into a 2D graph with the index of the vector as the y and the vector as the x

([vector1], 1), ([vector2], 2), ...

推荐答案

以下是一个简单的选择:

Here's a simple option:

% some arbitrary data:
CellData = {rand(10,1)*50,rand(10,1)*50,rand(10,1)*50};

% Define x and y:
x = cell2mat(CellData);
y = ones(size(x,1),1)*(1:size(x,2));

% plot:
plot(x,y,'o')
ylim([0 size(x,2)+1])

因此您将x的每个矢量绘制在单独的y值上:

so you plot each vector of x on a separate y value:

只要您的单元格数组只是矢量列表，它就可以工作.

It will work as long as your cell array is just a list of vectors.

适用于非相等向量

您必须在hold中使用for循环:

You'll have to use a for loop with hold:

% some arbitrary data:
CellData = {rand(5,1)*50,rand(6,1)*50,rand(7,1)*50,rand(8,1)*50,rand(9,1)*50};

figure;
hold on
for ii = 1:length(CellData)
    x = CellData{ii};
    y = ones(size(x,1),1)*ii;
    plot(x,y,'o')
end
ylim([0 ii+1])
hold off
