I modified a code (found here in the forum) to produce a stacked bar chart. Unfortunately I do not understand the whole code…

How can I center the values within the bar chart or right beside the chart? Unfortunately there are values outside the chart (0.430, 0.054, …)!

Furthermore: How can I change the Formate? 0.430 --> 43.00% and so on?

Link to original code.

You only need to change the anchor of the nodes near coords. (I also changed the text color of the lowest nodes for a better readability.)
