QUESTION
I am grouping columns and identifying rows that have different values for each group. For example: I can group columns A,B,C,D and delete column A because it is different (Row 2 is 2.1). Also, I can group columns E,F,G,H and delete column G because Row 1 (Row 0 is Blue).

QUESTION
I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.
...ANSWER
