Gabor is correct - You can't do this in the "vanilla" sense but you can manipulate a bar chart or use a extension.
Doing an image overlay is simple enough in QlikView but I cant see an easy option in Qlik Sense
However, you could try this very "Old Skool" solution
You could create 5 images (one for each layer) using a tool such as gimp or create them in word/powerpoint and use a snipping tool to save them.
Save them in your graphics/media library (if your using QS desktop I think the path is: \documents\qlik\sense\content\default).
Then drag a text object onto your document with the relevant image set as the background and the text set as your expression (='Crisis '&Whatever your expression is) .
I'm certain there are better ways to do it but it's just an idea
