JQuery Flot：清晰的图形

Question

Is there a recommended way to clear a jQuery Flot graph? I couldn't find anything the in the API reference.

Answer 1

By "clear" do you mean "nuke the entire graph," or just clear the data?

To nuke the entire graph: $('#canvas_id').empty();

To clear the data, just call the usual $.plot(placeholder, data, options); where data is empty.

Answer 2

in my case just clearing container won't help, some flot bindings stil working.

var plot = $.plot(placeholder, data, options);
// some other code
//to completely remove flot chart call
plot.destroy(); // remove graph and all bindings

to clear only graph use Matt Ball ansver.
