It's been a while since I last used a charting library (d3) for taking input like OHLC and other data series of my creation, and plot them in Chrome.
What is the best trading-oriented charting library currently available? I am starting a new framework from scratch, so I am open to using JS or Python, although honestly it would be better if it was available in PHP because this is going to be a FIO project and FIO is in PHP.
I would love to have a discussion pointing me to the best current projects.
I need to:
- Plot OHLC time series data
- Show comments on chart, such as FIO usernames
- Overlay multiple plots on top of each other with different scales
- Multiple panel support, ie panel 1=price and panel 2=other data series
The data itself will be generated server-side, I am searching only for the library to help me plot it.
