I’m generating candlestick plots for larger datasets (5m intervals for 2 months) and i’m having problems with performance.
The stored html file is roughly 5Mb - but opening the plot in chrome results in a lagging plot, where zooming takes multiple seconds.
It’s not memory (the tab takes ~200Mb of memory) - nor cpu (almost no cpu usage according to Chrome task manager), but still it’s slow.
There’s “only” 17000 candles in this plot, which does sound like a lot, but it really isn’t (it’s only 2 months - i would have data for 2 years …).
i assume using webgl would fix this - but i couldn’t find any reference to a candlestickgl chart.
My plan was to use dash in the future (with the same data) for visualization, but this performance will be unacceptable to users.
Is there a way to use plotly for this type of plot, or do i need to search for specific charting libraries that support this amount of data better?
