How to display overlapping labels on horizontal stacked bar

Hi

I have a horizontal stacked bar with 7 segments. When I display labels (with font 8 or 9) they are overlapped and not readable. What is the best way to show them?
I was thinking to use a text box to place the labels there in the same order as the segments are, and then place the text box in the gap between each two bars. This is very time consuming. I have 50 bars with an overall 350 labels for all bars. Could someone please assist me with this query.

Thanks in advance!

Thanks for your reply. But I meant the extent that the labels could exist. However, I need to display labels on selective bars in a neat and readable form. Any ideas?
