Delta Arrow in Bar Chart

Community Help

Dear Observable Community,

I am looking for a way to insert an arrow into a bar chart which indicates the delta between the cumulated values. Since I am quite new to Observable I don’t even have an idea where to start. I experimented a little with plot.line but it did not work for me. Especially since the y values are categorical… :frowning:

I published an example with the Visualization at the moment and a picture with the Visualization I hope for (yes the latter was created in Powerpoint, but maybe it’s not stupid if it works):

A tipp how to set this up would be great!
Thanks in advance!

Cheers, Till

There are line, arrow, and text marks available for Plot that you can use to supplement your picture. I’ve sent you this suggestion to illustrate. The result looks like so:
