Matlab 问题 : fixing the scale of Y axis in hist

Question

我想绘制几个直方图。但是我希望 Y 轴是固定的，比如从 1000 到 1 乘以 100。我该如何指定它们。

请指教。

Answer 1

考虑这个例子:

%# some data
X = randn(1000,3);
nbins = 10;

%# compute frequencies and bins
%#[count,bins] = hist(X, nbins);
count = zeros(10,size(X,2));
bins = zeros(10,size(X,2));
for i=1:size(X,2)
    [count(:,i),bins(:,i)] = hist(X(:,i),nbins);
end

%# show histograms
for i=1:size(X,2)
    subplot(1,size(X,2),i)
    bar(bins(:,i), count(:,i),'hist')
    set(gca, 'YTick',0:100:4000, 'YLim',[0 400])
end
