Different colors Bar Chart (JavaScript) + CSS editor

Hello, I need someone to help me with some ideas on how I can implement a Bar Chart that represents service values with different colors, which I designate in the Rule Engine node. My table is formed as follows.

I’ve tried several ways, using CSS Editor nodes, String Manipulation to create a class where it contains the color and the value of “LISTA(NIVEL_S)” and pass it to the CSS editor, but I can’t manage to color the bar charts with the colors I want.
