Data labels in a 100% stacked bar chart / adding a value

Question

Hello,&nbsp;I have a 100% stacked bar chart that displays per country the product sales. (I've reduced my products in the top 3, so that for each country i have these only). I want to add next to each line (country) the value that corresponds to the revenue per country but in total for all products. Is it possible?&nbsp;&nbsp;

Not with the standard visuals. Use Deneb or similar to create your own visual .

So, the only option I actually have is to create a custom visual. Do you think that i could it maybe using python code?

lbendlin · Answer

if that Python code renders the chart, yes.

I tried this code, but it does not display the visual as I expect:I want in axe Y the countries and then display the apples, lemons and oranges in a 100% stacked bar chart. At the end of each bar to display as label the revenue for each country&nbsp;{
