Hi KatiRG,
I have been trying to modify your code in order to make a horizontal version of your visualization. Yet have had no success after several attempts. Is it possible for you to upload a version like this please?
Thanks!

Hello,
I am trying to create a stacked graph similar to this one and have tried building it off of your original design. One difference is that I am trying to allow for multiple selections from the legend instead of just one. So far I have had a bit of trouble with this. Do you have any tips or samples that could point me in the right direction? I'd be happy to share my changes at this point for you to get a feel for the direction I am taking.
Thanks!
