中的数据描述了每个粒子多少邻居我有，我希望做的是重新present这个数据直方图这样就可以很容易地想象我有多少时间有6个neihbours多少次4，5， 7，8 ...肯定这是我很难在字里行间，看看有多少6或X号我有，如果有人能帮助提出一个方法在直方图我重新present和量化这些数据d是感恩
the data describes for each particle how many neighbours I have,what I wish to do is represent this data in histogram so that one can visualize easily how many time I have 6 neihbours how many times 4 ,5 ,7 ,8...sure it's hard for me to read between the lines and see how many 6 or X number do I have if anyone can help to suggest a way to represent and quantify these data in a histogram I'd be thankful
修改：下面回答生成柱状图与百分比
EDIT: Answer below for histogram generation with percentages.
我绘制使用直方图：
[nelements,centers]=hist(cellfun(@numel,S));
numNeighbors = cellfun(@numel,S);
[nelements,centers]=hist(numNeighbors,unique(numNeighbors))
pcts = 100 * nelements / sum(nelements)
figure
bar(centers,pcts)
显示在y轴上的每个xvalue次数的百分比，现在有可能显示在直方图中的百分比数字作为我的图片中加入上述这样可以很容易地可视化的数字???
displaying on the y axis the percentage of each xvalue occurance,now is it possible to show the percentages numbers on the histogram as I added in the image above so one can easily visualize the numbers ???
推荐答案
说你的电池阵列是 C ，然后尝试 HIST（cellfun（@ numel，C））。为了更好的展示，也许：
Say your cell array is C, then try hist(cellfun(@numel,C)). For better display, maybe:
numNeighbors = cellfun(@numel,C);
hist(numNeighbors,unique(numNeighbors))
