Show labels on stacked Bar Chart in sections #42

Closed ABausG closed 2 years ago

ABausG commented 2 years ago

Hello,

I want to show the values of a section in a stacked bar chart inside the section. Is there a way to do that? By using ValueDecoration I was only able to produce a label for the whole bar.

Hey @ABausG

You might want to check out SelectedItemDecoration. It is meant for selected item and clicking but it can also be used as sections and have multiple of them with different selectedItem id.

I was able to get it working with the ValueDecoration and the valueArrayIndex However I noticed that as the alignment is based on the max value the label is not the desired one if it should be the amount of the respective section. I have added a function to generate a label based on the item in addition to the value. I will open a PR soon
