This chart can be improved in many ways (source), you can see it without understanding German…
- No need to repeat “Mrd. Euro” (billions of Euros) at every data point, just put the unit at the top
- The data labels of the second data series is missing, as is the total
- The color of the 2nd data series is too light (probably to make the text readable)
- I would right-align the row labels
