comment Specify marker color to come from colormap in @pre marker code
Hi ope, welcome to the site! Could you turn your code snippet into a complete but minimal example document (starting from \documentclass), including some dummy data, to make it easier to start working on a solution?

comment Regression with .csv tables
Hi Charles, welcome to the site! In general, it's preferred to include a minimal working example instead of code snippets, i.e. a complete document (starting with \documentclass) that can be compiled without changes and that includes only the minimum code necessary to demonstrate the problem. The code I included in my answer is an example of how such a document could look in your case.
