Stacked Charts: Label Alignment

[Anna-Lena1998]

Is your feature request related to a problem? Please describe.
As a user I cannot define, how the labels of a stack within a Stacked Chart are aligned within a stack

Describe the solution you'd like
Therefore, a new property e.g., alignLabels would be helpful in order to be able to set the alignment of a label within a stack. By default, the label shall be centred.
