Unfortunately finplot is not the shit. Over the last year, both finplot's and mplfinance's github stars have been increasing constantly. finplot with 20/month, mplfinance with 80/month.
Over the last month, mplfinance was downloaded 15x more than finplot! Perhaps users want Jupyter, web and a large community, but I had thought that a great API and high performance would win exponentially more traders. I was wrong.
Nonetheless, this is my most successful project to date. Not financially, but in terms of use. There are things I could explore to possibly earn money, such as add-ons or services, but I'm content with what I have. Version 1.8.2 is just out, with the same super-slick API and as high performance as previous versions. In the latest change I was finally able to move the price axis to the right-hand side.
Take it for a spin, it's more than 15x better than mplfinance! :) Enjoy!
