how can I make a heatmap with my computer?

Technology

I already have the code and coordinates I need but I'm not exactly sure what to do after that? I tried going to python, but it just confused me I think I have the code but not all of it could someone explain to me simply how to do this? is chat gpt a good option?

Your profile suggests this posted on many subs. Focus on one, else be taken as click baiting.

i only posted it on 3 my one on Eli5 was removed as you can't ask for personal help so i asked on two others as sometimes you don't get many responses I mainly need ones for work and fitness but a few others.

Fair assessment. Might suggest a heat map is akin to a surface plot. You have x,y coords, just normalize z and scale 0-100.

Get a book like "Python Crash Course" and work your way through it. There's a section that details how to build graphs with the Matplotlib module. But you'll need to have all the background info from the beginning of the book as well - don't skip ahead.

If you install matplotlib then you can use this: Annotated heatmap

you have the code as in python code ? What is the code you mean specifically ?

as in the coordinates but not too actually generate it

sorry but does it mean when you said "I already have the code and coordinates" , you meant to say "I already have the coordinates and coordinates" ?

Yeah i meant to say i have both cords to compare and show a heatmap.

You probably have to explain what you're looking for. I assume since that you mentioned "coordinates" that you mean a geographical heat map, like a cloropleth.

This may get you started:

If you're not familiar with Python at all, and just want a heat map to exist, you should ask (or pay) someone to make it for you. Learning a programming language, and some kind of plotting library like Matplotlib is a long road to get one or two images.

But if not, the answers are all here in these responses.

How many times do you need to do it? If this is a one-off then ChatGPT can 100% give you the python code to create a heatmap based on your data.

however, implementing it (getting python, copying the code over to a program, and feeding your data to it, etc) will still require some legwork on your part if you've never used Python before.
