I believe you've seen samples of Stacked Bar Chart, that means that in general this Excel object works. Why it doesn't work in you case - that could be tons of reasons, e.g. you selected wrong range as data source, or you have texts instead of numbers, whatever. Without sample file it's hard to say something concrete.

With permission from everyone, if I may add to the very good implementation by Mr. Sergei Baklan (@Sergei Baklan).
I added the same file that you will find in the link. You can download it directly.
Thank you for your patience and time.
