  • 0

I’ve got some code in Python that I’d like to start trying to turn into a web app (not sure what framework I’ll use yet, but it will be python-based). The idea is that the user punches in a bunch of numbers, and a graph is updated after each is entered.

Currently I’m doing this with python + matplotlib. My initial thought was to re-render a jpg of the image each time the user punches in a new number, but this seems a little heavy.

I’m wondering, what is a technology I should look at for incorporating a dynamic graph into my web application?

    regenerating a jpeg for every number would be very heavy.

    Javascript provides a number of extremely high quality free graphing libraries:

    In addition to the above link there are tons of stack overflow posts on javascript graphing libraries.

    If you need to process each user input with python then i would consider using ajax. It could be like:

    1. user inputs a number
    2. browser/javascript makes an ajax request to your python app
    3. python processes and returns the appropriate data
    4. browser recieves response and updates the JS chart
