I'm not so good at English but points are: - Websocket to send raw point data batch by batch - Strip the float value to integer if possible or multiple it before sending if it won't exceed Number.Max_Integer or something alike - The front-end should build wrapper around the received raw data for indexing so that no need to modify the data - There should be drawing/chart libraries handling the rendering quite well with proper data format with batched data
