I am trying to get some recommendation, advice how to replace my current process where I use local macro excel with JS to reproduce Psychrometric Chart. I have macros in excel with calculation that I generate data and then use excel Chart formula to draw each chart line. At then end I am annotating on chart background process arrow lines. I want to ultimately reproduce same process and allow displaying on the web both input assumptions as I have a the left hand side and chart. I want to iterate via each space and plot individual chart and print/save or send as PDF.
I collected existing posts but I could not find solution that show me this level of complexity. Most of example below are just simple two variable linear lines.
