How to separate lookup "tags"

Hi everyone, I’m new to Coda here. I ran into a question when trying to display my table in a graph.

For a column, I’ve selected the format to be “Lookup” and I’ve also allowed “Allow Multiple Selections”.

Let’s say for my lookup table, I’ve made different color “tags” - red, blue, yellow, green, purple. For my column, since I allow multiple selection, some rows will have multiple “tags” yellow, green.
When I tried to visualise my data, yellow, green will become its own category. Is it possible to separate them back to tracking only yellow or only green? I’m trying to make a piechart and want to separate the multiple selections, so each selection is an individual category. Thank you!

Hey there! Welcome to Coda and the Coda community! You can definitely do this. See my example document below.

Essentially, you are going to create a new table that will display as your graph that is not the table you are making the selections in. I chose it to be the initial lookup table itself and wrote this formula:

Then display that table as the pie chart

Thank you, Scott! It works!
