How to combine stacked bar chart and line chart?

I'm finding a way to combine a stacked bar chart and line chart look like this:
I have tried to use 2-axes graph in (https://www.mathworks.com/help/matlab/creating_plots/overlay-line-plot-on-bar-graph-using-different-y-axes-1.html)
and used the following code:
yyaxis left
b = bar(step,array,'stacked');
yyaxis right
p = plot(step,entropy);
But it seems not to work properly and the result is:
PS: I have 4 components in 1 bar. Sometimes, there's only 1 component presents inside the bar. The line graph works as expected though. Only the stacked bar has problems.

Seems to work fine here...
figure
hB=bar(step,array,'stacked');
ylim([0 16])
xlim(xlim+[1 -1]*500)
yyaxis right
hL=plot(step,randi(15,1,6),'*-r');
yielded
The figure you show must have had 10-gazillion x values to have made such a blob.

Hmmm...that's also reproducible here on R2019b; which release are you using?
I had never noticed a similar anomaly with the yyaxis pair before, but I've not used it all that extensively other than here in Answers so don't know that had ever tried a stacked bar plot before.
It isn't unique to the 'stacked' option, either; a regular bar doesn't show different bar colors either as it should.
This appears to be a bug, indeed. Submit a bug report using the "Contact Us" link <ContactTMW Link>

I reached out internally. This is the expected behavior, but it's also fairly simple to change this back to what you would have expected by setting the colororder back to 'default'.
step = 1:1000:5073;
array = [0 0 15 0
4 1 10 0
0 0 15 0
4 1 10 0
15 0 0 0
0 0 15 0];
figure
yyaxis left % I added this line to regenerate the error
bar(step,array,'stacked');
ylim([0 16])
xlim(xlim+[1 -1]*500)
% reset colororder
colororder('default')
yyaxis right
plot(step,randi(15,1,6),'*-r');

Stacked bar plots do, as you've shown above. It is the call to yyaxis that is changing axis properties. Expected behavior means the code is doing what it was written to do. It doesn't mean someone considered this exact scenario and decided this was what people would want. The feedback has been given. My purpose here was to provide a workaround while the feedback is considered.
