Expected behaviour

When I am re-rendering the Areachart and series-label.js plugin with setInterval function it should run without any error in the console.

Actual behaviour

But while I am running I am getting the following error frequently but not all the times:

Uncaught TypeError: Array.prototype.forEach called on null or undefined
at forEach ()
at a.each (highcharts.js:formatted:528)
at a.Chart.A.drawSeriesLabels (VM320 series-label.js:formatted:197)
at VM320 series-label.js:formatted:49

Hi @VBIManonmaniM

Thank you for reporting this bug. I was able to recreate the issue when clicking on legend items very fast - sometimes, during initial animation, I was able to get this error.
