Data Visualization - Bar Chart - error #10

JavaScript
1

I am trying and trying to find my error here, but I am really stuck
https://codepen.io/vaupunkt/pen/poxGGgz

I am getting Error #10 all the time:

10. The data-date attribute and its corresponding bar element should align with the corresponding value on the x-axis.

I would be very happy with a code-review or a hint, where my mistake is :slight_smile:

THANKS A LOT!
