Need help with Django web app & ready to help you with your project!

In your view, call the code that generates the image, and return a Response with the binary data return HttpResponse(binary_image_data, content_type="image/png")

You will want to decide if the user data should come from the GET query_params or in POST data. But it depend on how you want to use the image. If perhaps you want to embed it in an html <img> tag, you could use query parameters and caching.

You have a few options:

• from the scipy docs: https://scipy-cookbook.readthedocs.io/items/Matplotlib_Django.html
• or you can use pygal or bokeh - these are python projects that create interactive charts for you
• or you can skip the plotting in python: do all you calculations in pandas, then pass the result to a front-end plotting library like chart.js

The last option is what I am doing for bar charts in https://yetanothersermon.host and it's working pretty well so far.

For the best UX you will want to create an AJAX function that takes in them two numerical values.

Then run your script inside that function and then either store the image on the hard drive or send it as the response.

Hope that helped, should give you some things to google.
