Hi, I am new to this JS ...
am looking for a fast way to display scatter plot in real time to display data points I captured via websocket.
So... I got the websocket part settled and was able to deliver the data to the respective charting JS... here is the pain I experienced in the past:
with Scatter plot rendering on SVG, it is painfully slow. I cannot render more than 5-10 times a second without choking the display or the browser.
This I have tried with CanvasJS, and flot to some degree of success but always not very satisfied with the rendering speed
(based on the google-chrome profiler, the time is really spent on the rendering of the charts)...
I am not interested in fills or lines or any thing pretty.. just the scatter points.
and when I move to a unix environment (behind Firewall unfortunately), it slow down to a crawl for even a very simple stream.
So I am looking into this one now... and am hoping that I can get your expert opinions to jumpstart on this.
Sincerely appreciate your kind advice.
PS: I could resort to QT for a better rendering engine... but thought that a JS based solution would be more platform independent... as such very willing to try things if they are in the right direction. thanks for your sharing!
