So im building a financial app that shows stock prices, so im wanting to show a candlestick chart.
Ill need it to be draggable and zoomable too
I have built one using the Expo SVG library but im finding it has
- poor performance drawing 600 candles worth of shapes (each candle is 3 shapes so 1800 paths)
- when I scale it, it starts to get blurry in some parts.
This obviously could just be me and my inexperience so before I continue on trying to make it better was wondering is SVG actually the best option
I see in the Expo SDK I have the ability to use
- Open GL via GLView
- Processing.js via GLView
- Three.js (this seems overkill)
Processing.js from the bit ive read seems to be geared towards data visualisations so im thinking that might be better?
Just a little lost on this one because I would have thought SVG would be the way to go as it can be infinitely scaled without losing its crispyness but im not finding that at all.
