Ng2-charts: Performance Issues

[alexcastillo]

Hi,

I have rewritten my app from Angular 1.5 + angular-chartjs to Angular 2 + ng2-charts and I'm experiencing a massive performance difference. I'm using sockets to update my chart 30 times per second. Maybe is related to the way rerendering is done in ng2-charts.

I was just wondering if you have done any performance tests or if you have any ideas for optimizing?

Thank you in advanced!

I'm looking forward to using ng2-charts for displaying brainwaves in real time.

Best,

Alex

@valorkin any progress on this?
It looks like the fix for this would address exactly the issue I've described in #291
