Wait for d3 to load

1.5k Views Asked by Ebikeneser At 21 March 2016 at 14:18

I am creating a pie chart using d3 to load a pie chart -

var pie = new d3pie(

     // pie control Json

);

This is working great however I am looking to do logic after the pie has fully rendered.

I have tried to use the when done logic (like when doing an ajax call) like so -

$.when(pie).done(function () {
     // further logic to be completed after pie has loaded

});

However this does not work in that it just steps into the when clause even tho the pie has not loaded fully. How can I do this?

You are looking for the onload callback:

callbacks: {
    onload: function(){
      console.log('chart is loaded!');
    }
}
