Bar chart based on comma separated list

I am looking for assistance trying to create a bar chart. I have a sensor with an attribute that consist of a comma separated list of values. I am looking to create a bar chart using these values simply in the order listed. I have been looking at the Apexcharts as I thought it should be able to do what I am looking for, but as far as I can tell, I need the values in an array combined with timestamps to build the data for the chart, and I am uncertain as to how I can do that.

Is what I am trying to do very complex, or am I just missing something really obvious?
