How can I get a stacked bar graph with a single bar?

Hello,

I am trying to get a single bar using the stacked property:

figure; bar([0.2 0.8], 'stacked')

This does not create a single stacked bar, it creates two bars of height 0.2 and 0.8.

A work-around is:

figure;bar([0.2 0.8; 1 1],'stacked'); set(gca,'xlim',[0.5 1.5])

But this seems like a silly thing to have to do.

Does anyone know why the stacked input doesn't seem to work for a single bar?

Thanks.

One possibility for a workaround:

v = [0.2  0.8];
figure; 
bar(sum(v), 'y')
hold on
bar(v(1), 'b')
hold off

Thanks, that works, but it is also a workaround. It seems like it should work without it.

My pleasure.

I want to plot bar (stacked) of 13 data. I tried the same code with a variable containing 13 data points(instead of 2 variable in your data). However, the output plot consists of last value only. Please help. Thanks.

this should work:

bar([1,2,3,4,5,6,7,8,9,10,11,12,13; nan(1,13)], 'Stacked');
set(gca,'xtick',1)

Found a very good solution for big data: how-do-i-create-a-stacked-bar-plot-in-matlab-that-fix-certain-values-to-specific

just add 1 line to limit the x axis:

bar([1,2,3,4,5,6,7,8,9,10,11,12,13; nan(1,13)], 'Stacked');
set(gca,'xtick',1);
xlim([0.25 1.75]);

Note that if you also actually specify x values and use a NaN there as well, you do not have to tweak the limits and ticks:

bar([1;nan], [1:3; nan(1,3)], 'stacked')

(requires MATLAB 2019b or later)

bar(1,[0.2 0.8], 'stacked')

Use the bar(x,y) synatax instead of bar(y). This way you can control if the bars are grouped.

I tried this an got this ERROR:

bar(1,[0.2 0.8], 'stacked')
% Error using bar (line 172)
% X must be same length as Y.

I wasn't aware when writing the answer, but this works only in MATLAB 2019b or later.

Do you maybe know how to remove the margins from left anr right? Thanks

@Daniel Do you know how to overlap the series instead of summing then? If you see your bar graph it is summing your data series, and stacking them. I would like to have the same graph but with the time series overlapped to highlight the difference between the serires. Thank you.
