Passing a large amount of data point will probably result in some kind of latency.It might even get slow just to send the data to the client, before the chart is rendered.
One option is just to try and see. In general, try to display less data, and if needed, drill down (although drill down is not yet an integral part of the library, you can just catch the event that the user zoom in, and then send a query to bring more dense data). There were already a few posts in this group about this. We hope to have some more concrete way to do this in the future.
