How to resize a Flot graph when its containing div changes size

Question

I'm using the Flot graphing library jQuery plugin and I haven't found a good way to handle resizing the graph when it's containing <div> changes size (for example, due to window resizing). When handling the onresize event, I've made sure that the width and height of the containing <div>are updated to the correct size and then tried calling both setupGrid and draw on the plot object but with no effect. I've had some success with the approach of just removing and readding the containing <div> and replotting the graph in it. However, this seems to be prone to getting stuck in infinite resize event loops if I have to add other <div> elements to the document at the same time (like for tooltips for the graph) as I'm guessing those can trigger resize events as well? Is there a good way to handle it that I'm missing?

(I'm also using ExplorerCanvas for IE in order to be able to use Flot, if that might have anything to do with it. I haven't really tried in any other browsers yet)

Answer 1

I seem to have found a solution, although I'm not entirely sure why it works. I'm still using the approach of removing and readding the containing <div> from the document and replotting the graph in it. However where previously I had been doing

window.onresize = redrawFunc;  //redrawFunc removes and readds the containing div and replots

which seemed to be prone to getting into what seemed to be an infinite loop depending on what the redrawFunc did to the document.

Instead I tried using jQuery's resize binding

$(window).resize = redrawFunc;

So far, no matter what other changes I make to the document in the redrawFunc I haven't had a problem with this approach getting stuck in a loop yet. I'm just not sure why.

I have found just binding to the resize event on the window and calling plot works really well. For example I have my data and options stored in variables on the page. Then I setup this on $(document).ready():

$(window).resize(function() {$.plot($('#graph_div'), data, opts);});
