JavaScript charts - dynamically adding data points

I am trying to dynamically add data points to jqplot as a result of AJAX received data, but I do not see a way to accomplish this. Is t开发者_如何学运维his not possible?

If it isn't, what other packages are available that can accomplish the same basic graphing plus allow for dynamic data?

You may want to check the example below on how this is handled in Flot. Flot is an open-source plotting library based on jQuery, like jqplot. Both libraries are very similar.

This is how fetching and plotting the data with AJAX would look like in code:

function fetchData() {
   $.ajax({
      url:      "json_fetch_new_data.php",
      method:   "GET",
      dataType: "json",
      success:  function(series) {
         var data = [ series ];

         $.plot($("#placeholder"), data, options);
      }
   });

   setTimeout(fetchData, 1000);
}
