Stacked bar plot not working correctly

I am trying to plot the stacked bar plot with negative values from the documentation page:

I am using Matlab R2018b. Is this a bug in the release version or is it just me?

It's a bug. Although not ideal, I used this as a work around.

t1 = X;

t2 = X;

t1(t1<0) = 0;

t2(t2>0) = 0;

subplot(2,1,1)

bar(t1,'stacked');

subplot(2,1,2)

bar(t2,'stacked');
