How to retrieve ChartJS instance after initialization

Question

I'm using (have to) a framework that will eventually create a Chart with ChartJS, but it doesn't give me the instance of the chart.

Is there a way of retrieving this instance having only the canvas Id?

Answer 1

Just loop through Chart.instances

Chart.helpers.each(Chart.instances, function(instance){
  alert(instance.chart.canvas.id)
})
