[martin]

i use with html5 websocket to receive, data , expect to show how many number of data received by counting length of array after split with ;
and then show dynamic number of graph

Martin,

Can you please explain the issue you are facing? It would also be useful if you can create a jsFiddle demonstrating the issue with minimal code.

If you are just looking for an example using jQuery, here is one.
