set graphics object ydata which is a cell
显示 更早的评论
I am trying to adjust the heights of a boxplot.
boxplot(1:10,[zeros(1,5) ones(1,5)], 'colorgroup', [0 1], 'colors', 'rb', 'orientation', 'horizontal')
h = findobj(gcf, 'tag', 'Box');
ydata = get(h, 'YData');
celldisp(ydata);
ydata{1} = ydata{1}*0.60;
set(h, 'YData', ydata);
Note that celldisp(ydata) displays:
ydata{1} =
1.8500 1.8500 2.1500 2.1500 1.8500
ydata{2} =
0.8500 0.8500 1.1500 1.1500 0.8500
And the above code gives the error:
Error using set
Conversion to double from cell is not possible.
How do I set 'YData', as it is a cell?
Please note, this is a simplified extraction from much more complicated code. In general, the elements of the cell ydata are NOT all the same length, hence you cannot just use cell2mat or something on ydata

If you look at h it's actually a 1x2 vector of handles. Thus you're getting the ydata from two separate handles and you'll need to change it for each individually. Simplest way is to use a for-loop
boxplot(1:10,[zeros(1,5) ones(1,5)], 'colorgroup', [0 1], 'colors', 'rb', 'orientation', 'horizontal')
h = findobj(gcf, 'tag', 'Box');
ydata = get(h, 'YData');
for ii = 1:numel(h)
set(h(ii),'YData',ydata{ii});
end
